A VLT/FLAMES survey for massive binaries in Westerlund 1: II. Dynamical constraints on magnetar progenitor masses from the eclipsing
Context. Westerlund 1 is a young, massive Galactic starburst cluster that contains a rich coeval population of WolfRayet stars, hotand cool-phase transitional supergiants, and a magnetar. Aims. We use spectroscopic and photometric observations of the eclipsing double-lined binary W13 to derive dynamical masses for the two components, in order to determine limits for the progenitor masses of the...
متن کاملAccurate fundamental parameters of eclipsing binary stars
The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WWAurigae, which is composed of two metallic-lined A-type stars. We also reanalyse the data on HD23642, an A-type eclipsing binary member of the Pleiades open clus...

متن کاملPhysical parameters and multiplicity of five southern close eclipsing binaries
Aims. Detect tertiary components of close binaries from spectroscopy and light curve modelling; investigate light-travel time effect and the possibility of magnetic activity cycles; measure mass-ratios for unstudied systems and derive absolute parameters. Methods. We carried out new photometric and spectroscopic observations of five bright (〈V〉 < 10.5 mag) close eclipsing binaries, predominantl...
متن کاملFundamental Parameters of Massive Stars
We discuss the determination of fundamental parameters of ‘normal’ hot, massive OB-type stars, namely temperatures, luminosities, masses, gravities and surface abundances. We also present methods used to derive properties of stellar winds – mass-loss rates and wind velocities from early-type stars.
