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.

Clara Froment has been awarded the European Solar Physics Division PhD Thesis Prize

5 years 8 months ago

The European Solar Physics Division Prize Committee has awarded its 2017 PhD Thesis Prize to Clara Froment, in recognition of her Thesis on the coronal heating problem and study of the physical nature of long-period pulsations in coronal loops, which was undertaken at the IAS. The ceremony took place during the 15th European Solar Physics Meeting in Budapest on September 7, 2017.

Gravity waves detected in Sun's interior reveal rapidly rotating core

5 years 10 months ago

Scientists using data from the GOLF instrument onboard the ESA/NASA SOHO solar observatory have found long-sought gravity modes of seismic vibration that imply the Sun's core is rotating four times faster than its surface. IAS is Principal Investigator of the GOLF instrument and has participated to this study.

Planet-hunter adopted

5 years 11 months ago

PLATO - Planetary Transits and Oscillations of stars - was adopted during a meeting of ESA’s Science Programme Committee held on June 20, 2017. This means that the mission can now move from the blueprint to construction stage. In the coming months industry will be asked to bid to supply the spacecraft platform.

Preparing for the next big solar storm: Scientists and users plan the solar-flare forecasting system of the future

6 years 4 months ago

The Sun is currently in a quiet phase ; the next activity peak is is expected to happen in about five years, but in any event, a big solar-storm can strike anytime, not just at the peak of the solar cycle. Scientists and representatives of industrial sectors affected by space weather met at the Met Office to discuss how the solar-flare forecasting system FLARECAST should be designed to best serve user needs.

The final CoRoT data have been released

6 years 9 months ago

The CoRoT team has released all the data produced by the mission. This is the result of several years of work, during which the team managed to interpret and filter the main artifacts produced by the instrument and the satellite, leaving a clean astrophysical signal, relevant for scientific analysis.
