Stellar and Solar Physics

Our team aims at providing answers to some key questions of solar and stellar physics, such as the heating process of the corona or the structure of solar and stellar interiors. The magnetic field playing a fundamental role in structuring the atmospheres of solar-type stars, it becomes possible to understand the coupling between the internal generation of magnetic field and its external signatures. The two major research topics are thus the dynamic and internal structure of the Sun and stars, and diagnostic and heating of the outer layers.

After a mission that lasted twice as long as planned, CNES’s CoRoT spacecraft—capable of seeing the vibrations of stars and hunting for exoplanets—is to be retired from service. Launched on 26 December 2006, the CoRoT space telescope has been co-led under CNES oversight by the Paris Observatory and the LAM ; IAS has participated to its development and data analysis, and hosts the CoRoT data centre.

On June the 20th, IAS organizes in the Lehmann amphitheatre (LAL, building 200 of University Paris-Sud) the conference “Atomic physics, plasma spectroscopy, and solar physics from space: Celebrating the achievements of Alan Gabriel”. This conference aims at presenting the status of atomic physics, plasma spectroscopy, and solar physics from space, put in the perspective of the achievements made with SOHO and the missions that followed. In addition, our friend and colleague Alan Gabriel will celebrate his 80th birthday.

ten years ago, on 2 December 1995, SOHO, the ESA/NASA Solar and Heliospheric Observatory was launched.
The images SOHO sent back to Earth have revealed our Mother Star as ever-changing, surrounded by a hot corona, featuring solar quakes on the surface and violent eruptions of particles into space.
On 2 December 1995 the joint ESA-NASA Solar Heliospheric Observatory (SOHO) was launched by an Atlas II-AS rocket from Cape Canaveral in Florida, US.

SOHO was designed to answer the following three fundamental scientific questions about the Sun:
