Discovery of a Long-Lived, High Amplitude Dusty Infrared Transient
(2016-08-11)
We report the detection of an infrared selected transient which has lasted at least 5 years, first identified by a large mid-infrared and optical outburst from a faint X-ray source detected with the Chandra X-ray Observatory. ...
Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
(2016-07-01)
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotometric system. Our aim is to apply this ...
A search for white dwarfs in the Galactic plane: : the field and the open cluster population
(2016-04-01)
We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H$\alpha$ Photometric Survey of the Galactic plane and Bulge (VPHAS+). We targeted 17 ...
