Virtual Babelsberg Starry Night

Talk (in German): Gezeitenwechselwirkung zwischen Sternen und Planeten (Nikoleta Ilic)

On Thursday, starting at 6 p.m., Nikoleta Ilic's lecture on the topic "Tidal interaction between stars and planets" from the Babelsberg Starry Night series will be online.

Stars and planets can interact with each other in different ways. One interesting but also important way is tidal interaction. Even though our solar system has eight planets, even the closest planet to the Sun is too far away to have a significant tidal effect on it. However, we are aware of tidal interaction because we can observe it between planets and their moons (e.g. the Earth and its Moon). The discovery of exoplanets has enabled us to measure the influence of tides between stars and planets. So far, we have observed many planets around other stars that are so close to their parent stars that measurable tidal interaction can take place. In this lecture, possible consequences of tides on stars will be explained.

This season, the Babelsberg Starry Nights will not take place on site at the AIP, but will come straight to your home: on the 3rd Thursday of each month from 6 p.m. The lectures are available at

or via the YouTube channel Urknall, Weltall und das Leben (Big bang, the Universe and Life) and can be viewed at any time afterwards.
