We present a method for the analysis of radial velocity (RV) measurements, in the context of searching for planets around chromospherically active stars. We...
Modeling the second solar spectrum . An empirical approach
We present an empirical approach to model the wing polarization of strong resonance lines. This procedure based on `last scattering approximation' (LSA) was...
Modelling dust production from AGB stars: open challenges, uncertainties and new discoveries.
The description of dust production by asymptotic giant branch stars (AGB) is matter of interest for a wide part of the astronomical community. In the light of...
Asymptotic giant branch (AGB) stars are among the most important gas and dust polluters of the Universe. The latest AGB evolutionary models take into account...
Modelling the emission of passive galaxy candidates at z∼3
Early-type galaxies (ETGs) are of crucial importance to trace back the galaxy mass assembly across cosmic time, yet their formation and quenching remain...
Modelling the Mg[b] Spectroscopic Index with the Tunable Filters of OSIRIS
We present our first attempt to model a new metallicity indicator for old and intermediate aged stellar populations on the basis of the Mg[b] absorption index...
