Pulsating chromosphere of classical Cepheids. Calcium infrared triplet and H profile variations
V. Hocdé, N. Nardetto, S. Borgniet +10
It has been shown recently that the infrared emission of Cepheids, which is constant over the pulsation cycle, might be due to a pulsating shell of ionized gas of about 15\% of the…
Asymmetric shocks in Cyg observed with linear spectropolarimetry
A. López Ariste, B. Tessore, E. S. Carlín +7
Aims: From a coherent interpretation of the linear polarisation detected in the spectral lines of the Mira star Cyg, we derive information about the dynamics of the stellar pho…
Dynamical structure of the pulsating atmosphere of RR Lyr - I. A typical pulsation cycle
D. Gillet, B. Mauclaire, T. Lemoult +5
RRab stars are large amplitude pulsating stars in which the pulsation is associated with strong shock wake propagating in the atmosphere. The objective of this study is to provide…
First observation of H redshifted emission in RR Lyr
D. Gillet, B. Mauclaire, T. Garrel +10
The so-called H third emission occurs around pulsation phase =0.30. It has been observed for the first time in 2011 in some RR Lyrae stars. The emission intensity is very wea…
An 8-mm diameter Fiber Robot Positioner for Massive Spectroscopy Surveys
N. Fahim, F. Prada, J. P. Kneib +22
Massive spectroscopic survey are becoming trendy in astrophysics and cosmology, as they can address new fundamental knowledge such as Galactic Archaeology and probe the nature of t…
Search for surface magnetic fields in Mira stars. First detection in chi Cyg
A. Lèbre, M. Aurière, N. Fabas +4
In order to complete the knowledge of the magnetic field and of its influence during the transition from Asymptotic Giant Branch to Planetary Nebulae stages, we have undertaken a s…
