The HST/ACS Survey of Galactic globular clusters (GGCs) is a HST Treasury project aimed at obtaining high precision photometry in a large sample of globular...

We discuss observations and seismic analyses for three multi-periodic delta Scuti stars in the Praesepe cluster: BU, BN and BV Cnc. For two stars (BU and BN Cnc...

The new generation of deep photometric surveys requires unprecedentedly precise shape and photometry measurements of billions of galaxies to achieve their main...

We study the variability of solar activity using new photospheric proxies originally developed for the analysis of stellar magnetism with the CoRoT and Kepler...

We identify a set of 18 solar analogs among the seismic sample of solar-like stars observed by the Kepler satellite rotating between 10 and 40 days. This set is...

Aims: We propose and explore a new diagnostic technique based upon the linear polarization emitted in Hanle-sensitive lines in disk-integrated stars where a...

The distinction between active and inactive small bodies in the Solar System has become more blended in recent years, with the discovery of objects exhibiting a...

The first known asteroid with the orbit inside that of Venus is 2020 AV 2. This may be the largest member of a new population of small bodies with the aphelion...

The observation of Near Earth objects (NEOs) allows us to study the physical properties of the smallest size bodies of our Solar System and help impose...
