To unravel this mystery, several teams with diverse skills from the Astrophysics Department had to come together, as the architecture that unites the star to its planet is highly complex.

An international collaboration led by a team from the Astrophysics Department/AIM Laboratory of IRFU has predicted and characterised the expected signature of internal magnetic fields in stars through their seismology - called asteroseismology.

An international team including researchers from the Astrophysics Department (DAp) of CEA/Irfu, working in particular at the laboratory for the Dynamics of Stars, (Exo) planets and their Environment  (LDE3), has been able to demonstrate that stars rotate faster than expected as they get older.

Lisa Bugnet is one of 35 young women researchers who won the L'Oréal-Unesco Fellowships for Women in Science in 2019.

An international collaboration, involving the Astrophysics Department-Laboratory AIM of CEA irfu, participated in the study of an exoplanetary system, Kepler-107 and revealed an amazing distribution of its 4 planets of which two seem potentially resulting from a giant impact.

The stars do not play dice! It is the extraordinary discovery that the researchers of the Department of Astrophysics-Laboratoire AIM of the CEA-Irfu made by succeeding in determining the orientation in the space of the axis of rotation of stars belonging to two clusters of stars, thanks to asteroseismology.

In an article published in the Astrophysical Journal, an international team including two researchers from the Astrophysics Department- AIM Laboratory at CEA-Irfu, successfully detected the trace of solar oscillations in the light reflected by the planet.

An international collaboration, involving the Astrophysics Department-AIM Laboratory of CEA-IRFU, managed to determine, from asteroseismology, that up to 65% of stars more massive than the Sun (between 1.
