Astrochemistry is a discipline that studies physico-chemical processes in astrophysical environments. Such environments are characterized by conditions that are substantially different from those existing in usual chemical laboratories. Models which […]

Habitable Planets Around White Dwarfs: an Alternate Mission for the Kepler Spacecraft
A large fraction of white dwarfs (WDs) may host planets in their habitable zones. These planets may provide our best chance to detect bio-markers on a transiting exoplanet, thanks to […]

Astrometric Detection of Exoplanets from the Ground
Astrometry is a powerful technique to study the populations of extrasolar planets around nearby stars. It gives access to a unique parameter space and is therefore required for obtaining a […]

Fundamental Parameters of Exoplanets and Their Host Stars
For much of human history we have wondered how our solar system formed, and whether there are any other planets like ours around other stars. Only in the last 20 […]

Seismic Constraints on Rotation of Sun-like Stars and Exoplanet Mass
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of observations of rotation and magnetic […]

The Habitable Real Estate of our Nearest Stellar Neighbors
We use the sample of known stars and brown dwarfs within 5 pc of the Sun, supplemented with AFGK stars within 10 pc, to determine which stellar spectral types provide […]
