It is too late to observe t he proto-solar disk\, but many of its properties can be inferred from the current distribution of planetesimals and using cosmochemical constraints on the chronology of planetesimal accretion and the isotopic heterogeneity of the disk. I will review the available data which can be used to recons truct the proto-solar disk. The view that emerges is that of a quite stand ard disk of about 90 au in gas radius and 45 au in dust radius\, forming p lanetesimals at two distinct epochs (one of which very early\, while the d isk was presumably still in Class-0 or Class-1 stage) and evolving towards a transition disk at the appearance of Jupiter and Saturn. Similarities a nd differences with the PDS70 disk will be discussed.\nNote: Host: Oliver Gressel\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Serena Criscuoli (National Solar Observatory | Boulde r\, CO\, USA) DTSTART:20260618T123000Z DTEND:20260618T133000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2352 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Julián Alvarado-Gómez DESCRIPTION:Speaker: Serena Criscuoli (National Solar Observatory | Boulde r\, CO\, USA)\nTitle: Using Spatially Resolved Solar Observations to Impro ve Models of Solar and Stellar Variability\nAbstract: Models of solar and stellar variability are essential for a wide range of applications\, from understanding the influence of solar irradiance on Earth's atmosphere to c haracterizing exoplanet host stars and improving the detectability of exop lanets. Over the past decades\, irradiance variability models have achieve d considerable success in reproducing many observed signatures of magnetic activity. However\, important discrepancies remain\, highlighting limitat ions in our understanding of how different atmospheric structures contribu te to spectral variability.\nIn this seminar\, I will provide a brief over view of current solar and stellar variability models\, discussing both the ir achievements and their outstanding challenges. I will then focus on one puzzling problem: the variability of the hydrogen Balmer lines. These lin es\, especially Hα\, Hβ\, Hγ\, and Hδ\, are among the most widely used diagnostics of stellar magnetic activity\, yet recent observations have r evealed complex and sometimes unexpected behavior\, including weak or even anti-correlated variations with traditional chromospheric activity indica tors such as the Ca II lines.\nI will present recent efforts to understand the origin of this behavior through a combination of disk-integrated obse rvations\, spatially resolved measurements\, and semi-empirical atmospheri c modeling. I will discuss how modern high-resolution observations enable us to identify the physical origins of these discrepancies and refine exis ting models. Particular attention will be given to recent observations acq uired with the IAG spectrograph and results from the Visible Spectro-Polar imeter (ViSP) at the Daniel K. Inouye Solar Telescope\, which provide new insights into the relationship between magnetic activity and Balmer-line v ariability in the Sun and solar-like stars. Finally\, I will present preli minary results from an analysis of synoptic ChroTel Hα and Ca II K observ ations\, which suggest that chromospheric features\, often neglected in cu rrent solar and stellar irradiance models\, may play a role in shaping chr omospheric variability\nNote: Host: Meetu Verma\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Antoine Strugarek (CEA Saclay | Paris\, France) DTSTART:20261015T123000Z DTEND:20261015T133000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2353 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Julián Alvarado-Gómez DESCRIPTION:Speaker: Antoine Strugarek (CEA Saclay | Paris\, France)\nTitl e: TBD\nAbstract: TBD\nNote: Hosts: Ilaria Civale and Katja Poppenhäger\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Andrew Pontzen (Durham University) DTSTART:20261112T133000Z DTEND:20261112T143000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2359 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Ewald Puchwein DESCRIPTION:Speaker: Andrew Pontzen (Durham University)\nTitle: TBD\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Boris Gaensicke (University of Warwick | Coventry\, U K) DTSTART:20260924T123000Z DTEND:20260924T133000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2361 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Julián Alvarado-Gómez DESCRIPTION:Speaker: Boris Gaensicke (University of Warwick | Coventry\, U K)\nTitle: TBD\nAbstract: TBD\nNote: Host: Axel Schwope\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Tobias Buck (Heidelberg) DTSTART:20261119T133000Z DTEND:20261119T143000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2365 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Ewald Puchwein DESCRIPTION:Speaker: Tobias Buck (Heidelberg)\nTitle: TBD\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Dominika Wylezalek (University of Heidelberg | German y) DTSTART:20261203T133000Z DTEND:20261203T143000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2366 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Julián Alvarado-Gómez DESCRIPTION:Speaker: Dominika Wylezalek (University of Heidelberg | German y)\nTitle: TBD\nAbstract: TBD\nNote: Hosts: Tanya Urrutia and Guilherme Co uto\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Paul Groot (UCT/SAAO and Radboud University) DTSTART:20260625T123000Z DTEND:20260625T133000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2369 CATEGORIES:Wissenschaftliches CATEGORIES:Wissenschaftlicher Vortrag CATEGORIES:öffentlich CATEGORIES:Kolloquium CONTACT:Ivan Minchev DESCRIPTION:Speaker: Paul Groot (UCT/SAAO and Radboud University)\nTitle: Ultra-compact binaries and gravitational-wave progenitors\nAbstract: TBD\n Note: Host: Alex Schwope\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:Colloquium | Eric F.

They are a crucial and powerful laboratory for testing our understanding of galaxy formation and evolution. However\, the extremely faint nature of these galaxies has long hindered in-depth studi es of them\, biasing our knowledge of galaxy physics towards only bright\, massive galaxies. With the advent of new\, powerful instruments capable o f carrying out deep\, large sky surveys (e.g.\, Euclid\, LSST)\, combined with the era of modern artificial intelligence (AI) tools\, we are opening a new window into a comprehensive understanding of the LSB galaxies. In t his talk\, I will present our recent and ongoing work on LSB galaxies. Thi s includes the development of novel AI tools for the automatic identificat ion and characterisation of LSB and dwarf galaxies\, investigating the rol e of environment in their evolution\, morphology\, and gas content. Additi onally\, I will also present some follow-up observing campaigns we did on extreme cases like ultra-diffuse and giant LSB galaxies.\n LOCATION:AIP\; Schwarzschildhaus\, Hörsaal END:VEVENT BEGIN:VEVENT SUMMARY:AIP Sommerfest (intern) DTSTART:20260701T130000Z DTEND:20260701T160000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2468 CATEGORIES:Internes CATEGORIES:Institutstermin CATEGORIES:öffentlich DESCRIPTION: END:VEVENT BEGIN:VEVENT SUMMARY:Lieder unterm Sternenhimmel DTSTART:20260605T173000Z DTEND:20260605T200000Z DTSTAMP:20260616T120926Z UID:www.aip.de-2472 CATEGORIES:Öffentliches CATEGORIES:Öffentlichkeitsarbeit CATEGORIES:öffentlich CONTACT:Axel Schwope DESCRIPTION:Benefizkonzert im Großen Refraktor auf dem Telegrafenberg mit Axel Schwope als Solist.

The Array hosts a number of new or upgraded\, s ix-telescope beam combiners that span the spectrum from the visible R-band to the near-infrared K-band with a range in available spectral resolution . The most recent are the Silmaril beam combiner that is a three-telescope instrument for H- and K-bands that is designed for very high sensitivity on fainter targets and the CHARA Array Integrated Optics Testbed (CHARIOT) that is a platform for characterizing integrated optic combiners. A seven th\, mobile telescope is now on-site for use with fiber optics for H-band beam transport. The mobile telescope will extend the baseline range from 2 0 m to 579 m\, creating new opportunities for measurements of stars with l arge and small angular diameters. Observing time is available to the commu nity through a program funded by NSF. The observing programs are solicited and peer-reviewed by NSF's NOIRLab.\nAbout Dr. Scott:\nNic Scott is the T elescope Systems Scientist at the Georgia State University Center for High Angular Resolution Astronomy (CHARA) Array. Nic directs all aspects of co ntrol and development of the telescopes\, enclosures\, and relay optics of the seven CHARA Array telescopes. Nic received dual PhD degrees from Geor gia State University and the Observatoire de Paris for his work on a novel fiber optics beam combiner at the Array. Prior to his current appointment at CHARA\, Nic was a Lead Research Scientist at the NASA Ames Research Ce nter where he developed speckle interferometry cameras for the WIYN\, Gemi ni-North\, and Gemini-South telescopes. Nic is currently leading the integ ration of the CHARA Array Integrated Optics Testbed (CHARIOT) experiment t o provide a flexible station in the beam combining laboratory to character ize novel integrated optics combiners.\nNote: Let me know if you want to m eet Nic.

But what if this foundat ion is starting to crack? In this talk\, I describe how we have used quasa rs and radio galaxies to test the assumption that the cosmos is isotropic and homogeneous. We know that the Cosmic Microwave Background displays a s trong dipole\, attributed to our motion relative to the local Hubble flow\ , and if this motion truly defines our cosmic frame\, its imprint should a ppear elsewhere. Indeed\, we find a dipole in large-scale surveys of cosmo logical sources\, and whilst the direction agrees\, the amplitude does no t\, diverging sharply from expectations based on the CMB. I will explore p ossible explanations for these tensions and ask whether they signal new ph ysics or a fundamental shift in our cosmological worldview.\n LOCATION:AIP\; Kirch-Haus\, Konferenzraum END:VEVENT BEGIN:VEVENT SUMMARY:AIP Seminar | Dr. habil.
