At the end of 2008, on ideas of teams from the Observatoire de la Côte d’Azur (OCA) and IAC, the CoRoT satellite observed the star HD 46375, known to host a non...

Long gamma-ray bursts are supposed to be connected to the death of very massive stars. Due to their brightness, we can detect them to much larger distances than...

Studying the Halo via Its NEarby low-mass Dwarfs (SHINED) is an ongoing project aiming to understand the Galactic halo with metal-deficient low-mass stars (LMS)...

The determination of chemical composition and distances of galaxies is crucial for constraining the theory of galaxy formation and evolution in a dark energy...

Exciting things may have happened sometimes to the stars we see in the sky today. For example, Betelgeuse, also known as Alpha-Ori, an M-type red supergiant...

We employ a Bayesian method to infer stellar parameters from the PARSEC v1.2S library of stellar evolution models and test the accuracy of these theoretical...

The theory of stellar evolution is well developed over the past decades, and in particular the predictions of one dimensional numerical models have passed basic...

I present the first results of a long term project devoted to the study of the evolution of the binary population in globular clusters. Using deep ACS@HST...

For most persistent low mass X-ray binaries (LMXBs) and transients in outbursts the optical emission is dominated by reprocessing of the X-rays in the outer...
