Parameter Estimation from an Optimal Projection in a Local Environment
A. Bijaoui, A. Recio-Blanco, P. de Laverny
The parameter fit from a model grid is limited by our capability to reduce the number of models, taking into account the number of parameters and the non linear variation of the mo…
The circumstellar envelope of IRC+10216 from milli-arcsecond to arcmin scales
I. C. Leao, Patrick De Laverny, D. Mekarnia +2
Aims.Analysis of the innermost regions of the carbon-rich star IRC+10216 and of the outer layers of its circumstellar envelope have been performed in order to constrain its mass-lo…
Doppler search for exoplanet candidates and binaries in a CoRoT field using a multi-fiber spectrograph
B. Loeillet, F. Bouchy, M. Deleuil +8
The discovery of the short-period giant exoplanet population, the so-called hot Jupiter population, and their link to brown dwarfs and low-mass stars challenges the conventional vi…
A snapshot of the inner dusty regions of a RCrB-type variable
I. C. Leao, Patrick De Laverny, O. Chesneau +2
R Coronae Borealis variable stars are suspected to sporadically eject optically thick dust clouds causing, when one of them lies on the line-of-sight, a huge brightness decline in…
The extra-mixing efficiency in very low metallicity RGB stars
Alejandra Recio-Blanco, Patrick De Laverny
AIMS: After the first dredge-up, low-mass Red Giant Branch (RGB) stars experience an extra-mixing episode that strongly affects the chemical abundances on their surface. This mixin…
Automated derivation of stellar atmospheric parameters and chemical abundances: the MATISSE algorithm
A. Recio-Blanco, A. Bijaoui, P. de Laverny
We present an automated procedure for the derivation of atmospheric parameters (Teff, log g, [M/H]) and individual chemical abundances from stellar spectra. The MATrix Inversion fo…
