The VLT-FLAMES Tarantula Survey: XXVII. Physical parameters of B-type main-sequence binary systems in the Tarantula nebula

Abstract:

A spectroscopic analysis has been undertaken for the B-type multiple systems (excluding those with supergiant primaries) in the VLT-FLAMES Tarantula Survey (VFTS). Projected rotational velocities, ve sin i, for the primaries have been estimated using a Fourier Transform technique and confirmed by fitting rotationally broadened profiles. A subset of 33 systems with ve sin i80 km s1 have been analysed using a TLUSTY grid of model atmospheres to estimate stellar parameters and surface abundances...
