Gas and dust from extremely metal-poor AGB stars
P. Ventura, F. Dell'Agli, D. Romano +8
We study the evolution of extremely metal-poor AGB stars, with metallicities down to [Fe/H]=-5, to understand the main evolutionary properties, the efficiency of the processes able…
An extensive spectroscopic time series of three Wolf-Rayet stars -- II. A search for wind asymmetries in the dust-forming WC7 binary WR137
N. St-Louis, C. Piaulet, N. D. Richardson +39
We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emiss…
An extensive spectroscopic time-series of three Wolf-Rayet stars. I. The lifetime of large-scale structures in the wind of WR 134
E. J. Aldoretta, N. St-Louis, N. D. Richardson +46
During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been analyzed for WR 134…
H spectral monitoring of epsilon Aurigae 2009-2011 eclipse
B. Mauclaire, C. Buil, T. Garrel +2
We present and analyze epsilon Aurigae data concerning the evolution of the H line on the occasion of the 2009 International observation campaign launched to cover the eclipse o…
