New Schwarzschild Fellow: Arianna Di Cintio

13 January 2017. The AIP welcomes Karl Schwarzschild Fellow Arianna Di Cintio. She completed her Ph.D. in 2014 at the Universidad Autónoma de Madrid in Spain, during which she also spent three mon...

Arianna Di Cintio's main interest is in galaxy formation and evolution, using numerical cosmological simulations. She focuses on small-scale problems of the current cosmological paradigm, trying to understand the nature of dark matter. Since 2011, she is part of the CLUES project, an international collaboration including AIP scientists, that aims at a better understanding of the properties of galaxies in the Local Universe. As a next project, Arianna Di Cintio is planning to investigate dwarf galaxies within the Local Volume together with AIP scientists from the Cosmology research section.

The Karl Schwarzschild Fellowship is awarded regularly with an alternating focus on extragalactic astrophysics and cosmic magnetic fields. The fellows should have received their PhD within the last five years and are identified in an  international search. They are expected to carry out an independent research programme and to contribute to the scientific life of the AIP including co-supervision of students.

The AIP continues the tradition of the Astrophysical Observatory Potsdam and the Berlin Observatory. It is located in the beautiful Potsdam/Babelsberg area, at the southwestern border of the Berlin metropolitan area. Over 150 scientists work on a variety of astrophysical topics covering the full range from solar physics to cosmology. Potsdam is also the home of the Albert-Einstein Institute for Gravitational Physics, the Physics & Astronomy department of Potsdam University and several other research institutions.

The key topics of the Leibniz Institute for Astrophysics Potsdam (AIP) are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aim at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. Since 1992 the AIP is a member of the Leibniz Association.

19.01. Starry night in Babelsberg

German lecture starting at 7:15 PM

Um 19:15 Uhr wird Dr. Jürgen Rendtel eine "Astronomische Jahresvorschau" geben.

Das astronomische Jahr 2017 bietet gute Gründe in den Himmel zu schauen: Zwei Verfinsterungen des Mondes können von Deutschland aus verfolgt werden. Eine totale Sonnenfinsternis ist in den USA gut zu sehen. Astronomisch betrachtet handelt es sich bei dieser Finsternis um ein Folgeereignis der damals auch in Deutschland gut sichtbaren Sonnenfinsternis aus dem August 1999! Darüber hinaus wird es um die Sichtbarkeit der Planeten, Bedeckungen heller Sterne durch den Mond, Meteorströme und mehr gehen. Zu den Erklärungen der beobachtbaren Ereignisse gibt es zudem Hinweise für die eigene  Beobachtung und Aufnahme-Tipps.


Im Anschluss bieten wir eine Führung über das Gelände und – bei klarer Sicht – die Beobachtung an einem unserer Spiegelteleskope an.

Wir freuen uns auf Ihren Besuch!

Freier Eintritt, keine Anmeldung erforderlich.


Veranstaltungsort: AIP, An der Sternwarte 16, 14482 Potsdam

Celebrating Ten Years of Science with STELLA

Celebrating Ten Years of Science with STELLA

8 November 2016. Since 2006, the two robotic STELLA telescopes of the Leibniz Institute for Astrophysics Potsdam (AIP) are observing the night sky at the Observatorio del Teide, Tenerife. STELLA is...

Over the past ten years STELLA has proved to be an excellent tool to accomplish thrilling scientific results. Since the telescopes were explicitly designed for long-term observation of individual objects, especially magnetically active stars, STELLA achieves this goal more easily than a lot of other telescopes. The robotic telescopes at Tenerife already observed complete magnetic activity cycles of distant stars and determined for the first time the decay time of star spots. On top of that, STELLA proved that there is rarely an exception to the principle that as stars age their rotation periods decrease, and vice versa proving that by knowing the rotation period of a star scientists can determine its age.

Operating a fully autonomous, robotic observatory is uncommon both in Germany and internationally. Replacing an onsite observer and their decision-making with a piece of software is a true challenge. STELLA has a meteorological station that constantly measures temperature, humidity, precipitation, and wind speed. A separate camera detects clouds obscuring the night sky. At dusk, an algorithm decides if conditions are safe for opening and commencing observations. All control duties, from positioning and focussing of the telescopes to the fineguiding system, are managed by the software.

Observatorio del Teide

The Observatorio del Teide has an international reputation in solar and stellar research. Lying in the middle of the Atlantic ocean on top of a volcanic mountain range, the astronomical observing conditions are close to optimal. In addition to STELLA, the AIP is also involved in the operation of the GREGOR solar telescope, Europe’s largest solar telescope, and the Vacuum Tower Telescope, both located on Tenerife.

The Dynamic Duo: RAVE complements Gaia

The Dynamic Duo: RAVE complements Gaia

19 September 2016. The new data release of the RAdial Velocity Experiment (RAVE) is the fifth spectroscopic release of a survey of stars in the southern celestial hemisphere. It contains radial vel...

The velocities and spatial distributions of stars define the galaxy we live in, allowing the characterisation of the formation of the Milky Way. Large spectroscopic surveys provide definitive measurements of fundamental structural and dynamical parameters for a statistical sample of galactic stars and have been very successful in advancing the understanding of our galaxy. RAVE started in 2003 and was the first survey designed to provide necessary stellar parameters to complement missions that focus on astrometric information like Gaia.

“The Tycho-Gaia stars that were also serendipitously observed by RAVE contain the best proper motions and parallaxes recently released by Gaia and can now be combined with the radial velocities and stellar parameters from RAVE”, says Andrea Kunder, lead author of the RAVE data release and astronomer at the Leibniz Institute for Astrophysics Potsdam (AIP), “So these stars can be used to probe the Milky Way more precisely than ever before. Just like wearing glasses allows you to see your surroundings in sharper view, the Gaia-RAVE data will allow the galaxy to be seen with more detail.“ Among existing spectroscopic surveys, RAVE easily boasts the largest overlap with the Tycho-Gaia  astrometric solution catalogue.

The four previous data releases have been the foundation for a number of studies, which have especially advanced our understanding of the disk of the Milky Way. The fifth RAVE data release includes not only the culminating RAVE observations taken in 2013, but also also earlier discarded observations recovered from previous years, resulting in an additional 30,000 RAVE spectra.

For the new data release atmospheric parameters such as the effective temperature, surface gravity and metallicities have been refined using gravities from asteroseismology and high-precison stellar atmospheric parameters. It also contains hypervelocity stars, some extra-galactic stars from the Large Magellanic Cloud, and some extremely metal-poor and metal-rich stars.

“The real treasure is that this is a large, statistically complete sample of local Milky Way stars, that can be used to find trends and anomalies for understanding the formation of the Milky Way,“ concludes Kunder.
