Discovery of a deep Seyfert-2 galaxy at z = 0.222 behind NGC 300
J. A. Combi, F. Garcia, M. J. Rodriguez +2
We report on the unveiling of the nature of the unidentified X-ray source 3XMM J005450.3-373849 as a Seyfert-2 galaxy located behind the spiral galaxy NGC 300 using Hubble Space Te…
The Galactic O-Star Spectroscopic Survey (GOSSS). III. 142 additional O-type systems
J. Maíz Apellániz, A. Sota, J. I. Arias +9
This is the third installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R~2500 digital observations select…
The eccentric short-period orbit of the supergiant fast X-ray transient HD 74194 (=LM Vel)
R. Gamen, R. H. Barbá, N. R. Walborn +5
Aims. We present the first orbital solution for the O-type supergiant star HD 74194, which is the optical counterpart of the supergiant fast X-ray transient IGR J08408-4503. Method…
MGB and the new Galactic O-Star Spectroscopic Survey spectral classification standard grid
J. Maíz Apellániz, E. J. Alfaro, J. I. Arias +9
In this poster we present three developments related to the Galactic O-Star Spectroscopic Survey (GOSSS). First, we are making public the first version of MGB, an IDL code that all…
Triggered star formation in a molecular shell created by a SNR?
Silvina Cichowolski, Serge Pineault, Roberto Gamen +3
We present a study of a new molecular shell, G126.1-0.8-14, using available multiwavelegth Galactic plane surveys and optical Gemini observations. A well defined shell-like structu…
Photometric and spectroscopic variations of the Be star HD 112999
M. A. Corti, R. C. Gamen, Y. J. Aidelman +2
Be objects are stars of B spectral type showing lines of the Balmer series in emission. The presence of these lines is attributed to the existence of an extended envelope, disk typ…
