PublicationO-star mass-loss and wind momentum rates in the Galaxy and the Magellanic Clouds Observations and theoretical predictions.
A new, very fast approximate method is presented to determine mass-loss rates of O-stars from Halpha_ line profiles. The method uses H and HeII departure...

PublicationOn the nature of the most obscured C-rich AGB stars in the Magellanic Clouds
The stars in the Magellanic Clouds with the largest degree of obscuration are used to probe the highly uncertain physics of stars in the asymptotic giant branch...

PublicationOn the use of field RR Lyrae as galactic probes - VI. Mixed mode RR Lyrae variables in Fornax and in nearby dwarf galaxies
We investigate the properties of the mixed-mode (RRd) RR Lyrae (RRL) variables in the Fornax dwarf spheroidal (dSph) galaxy by using B- and V-band time series...

PublicationOutside-In Disk Evolution in the Large Magellanic Cloud
From the analysis of the color-magnitude diagrams and color functions of four wide LMC fields located from ~=2 to 6 kpc from the kinematic center of the LMC we...

PublicationPhotometric and Polarimetric Observations of the Wolf-Rayet Eclipsing Binary HD 5980 in the Small Magellanic Cloud
We present results of photometry and photopolarimetry of the Wolf-Rayet eclipsing binary system HD 5980 in the Small Magellanic Cloud, which underwent an...

PublicationPlanck early results. XVII. Origin of the submillimetre excess dust emission in the Magellanic Clouds
The integrated spectral energy distributions (SED) of the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) appear significantly flatter than...

PublicationProperties of the Be-type stars in 30 Doradus
The evolutionary status of Be-type stars remains unclear, with both single-star and binary pathways having been proposed. Here, VFTS spectroscopy of 73 Be-type...

PublicationQuantitative spectroscopy of O-stars in the Magellanic Clouds. I - The young open cluster NGC 346 in the SMC
Results are presented on a non-LTE analysis of high-resolution Cassegrain echelle CCD spectra of the four most luminous stars in the NGC 346 cluster in the SMC...
