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…
Four newly discovered HII galaxies
O. Garde, P. Le Dû, M. Koenig +3
We present the results of spectroscopy campaigns for planetary nebula candidates, where we have identified four objects as Seyfert galaxies. All observations have been carried out…
Shape models of asteroids based on lightcurve observations with BlueEye600 robotic observatory
Josef Durech, Josef Hanus, Miroslav Broz +14
We present physical models, i.e. convex shapes, directions of the rotation axis, and sidereal rotation periods, of 18 asteroids out of which 10 are new models and 8 are refined mod…
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…
Searching for Trans Ethyl Methyl Ether in Orion KL
B. Tercero, J. Cernicharo, A. López +6
We report on the tentative detection of Ethyl Methyl Ether (tEME), , through the identification of a large number of rotational lines from each one of the…
