Saas Fee 2024: From stars to planets in the space-based photometry era

28 Jan 2024, 08:30 → 3 Feb 2024, 12:00 Europe/Zurich

In the context of the exponential  development of both fields of asteroseismology and exoplanetology, the precise and accurate characterization of planet-hosting stars appears as a perfect example of fruitful synergies between two dynamic research fields. Asteroseismology is now the golden path to constrain the internal structure and evolution of stars, impacting the precision of planetary parameters and the understanding we have of exoplanetary systems. In parallel, the diversity of observed exoplanetary systems has now pushed scientists to attempt at characterizing the dynamical and atmospheric evolution of exoplanets, to link their properties to the evolution of their host stars. This has called for further analyses of star-planet interactions to explain observational features and better understand how these interactions shape the properties and evolution of exoplanets.

In this Winter course, we propose to cover three topics: first the study of solar-like oscillations in the context of the study of exoplanet host stars. Second, we will cover the various types of star-planet interactions possible, such as tidal, radiative or magnetic interactions. Last but not least, we will also cover the link between the properties of planetary systems and their host stars. 

Invited Lecturers: Dr. Maria Pia Di Mauro, Prof. Aline Vidotto, Dr. James Owen.

This course is the 53rd iteration of the "Saas-Fee Advanced Course of the Swiss Society for Astronomy and Astrophysics" that has taken place since 1971. It will take place in the Swiss Alps, in the village of Saas-Fee from the 28th of January until the 3rd of February.

The number of participants is limited to 60.
