Abstract We present preliminary results of our spectroscopic campaign of a group of intermediate mass interacting binaries dubbed “Double Periodic Variables” (DPVs), characterized by orbital light curves and additional long photometric cycles recurring roughly after 33 orbital periods (Mennickent et al. 2003, 2005). They have been interpreted as interacting, semi-detached binaries showing cycles of mass loss into the interstellar medium (Mennickent et al. 2008, Mennickent & Kołaczkowski 2009… Expand


CoRoT photometry and high-resolution spectroscopy of the interacting eclipsing binary AU Monocerotis
Analyses of very accurate CoRoT space photometry, past Johnson V photoelectric photometry and high-resolution echelle spectra led to the determination of improved and consistent fundamental stellarExpand
Double-periodic blue variables in the Magellanic Clouds
We report the discovery, based on an inspection of the OGLE-II database, of a group of blue variables in the Magellanic Clouds showing simultaneously two kinds of photometric variability: aExpand
A study of the interacting binary V393 Scorpii
We present high resolution J-band spectroscopy of V 393 Sco obtained with the CRIRES at the ESO Paranal Observatory along with a discussion of archival IUE spectra and published broad bandExpand
Revealing the nature of double-periodic blue variables in the Magellanic Clouds
We present the first spectroscopic data for a sample of the recently discovered blue double-periodic variables in the Magellanic Clouds. The optical spectrum of these objects is dominated by BalmerExpand
Light Curves of Galactic Eclipsing Double Periodic Variables
We present results of the investigation of the nature of double periodic variables (DPVs). We have selected a sample of Galactic eclipsing DPVs for a multiwavelength photometric study aimed to revealExpand
