Kirchhoff Institute for Physics

The Kirchhoff Institute for Physics (KIP) is named after a prominent physicist of the 19th Century: Gustav Robert Kirchhoff, who worked in Heidelberg for 21 years. His well-known lectures on experimental and theoretical physics attracted many students. Kirchhoff's ground-breaking research was extraordinarily diverse, spanning electrical, magnetic, optical, elastic, hydrodynamic and thermal processes. His laws for electrical circuits are well-known. At the time he was in Heidelberg, in conjunction with Robert Wilhelm Bunsen, he discovered spectral analysis and its application to solar radiation. In this way, Kirchhoff laid the foundation for modern astrophysics, as well as formulating the laws of thermal radiation, which played a key role in the discovery of quantum physics. The KIP aims to continue in this tradition of diverse scientific research and education.

8. July 2022 5:00 pm  The Power of asteroseismology: probing stellar interiors

Prof. Dr. Saskia Hekker, HITS and Heidelberg University, The field of Asteroseismology — the study of the internal structures of stars through their global intrinsic oscillations, has been revolutionised over the past decade. This revolution was possible thanks to the high-precision high-cadence photometric data from space missions CoRoT, Kepler, K2 and TESS. These missions provided long timeseries data for hundreds of thousand stars. In many cases the brightness variations in these timeseries data reveal the intrinsic eigenmodes of the stars. These eigenmodes are defined by the internal structure of the star and hence, the stellar structure can be derived from the frequencies of the eigenmodes. more...
