Abundances of refractory elements in the atmospheres of stars with extrasolar planets
G. Gilli, G. Israelian, A. Ecuvillon +2
This work presents a uniform and homogeneous study of chemical abundances of refractory elements in 101 stars with and 94 without known planetary companions. We carry out an in-dep…
Abundance ratios of volatile vs. refractory elements in planet-harbouring stars: hints of pollution?
A. Ecuvillon, G. Israelian, N. C. Santos +2
We present the [X/H] trends as function of the elemental condensation temperature Tc in 88 planet host stars and in a volume-limited comparison sample of 33 dwarfs without detected…
Impact of gravity waves on the middle atmosphere of Mars: a non-orographic gravity wave parameterization based on Global Climate modeling and MCS observations
G. Gilli, F. Forget, A. Spiga +7
The impact of gravity waves (GW) on diurnal tides and the global circulation in the middle/upper atmosphere of Mars is investigated using a General Circulation Model (GCM). We have…
Abundance ratios of volatile vs. refractory elements: hints of pollutions?
A. Ecuvillon, G. Israelian, N. C. Santos +2
We present the abundance ratios [X/H] of a large set of chemical species with condensation temperatures from 75 to 1600 K in an almost complete set of 105 planet-host stars and in…
