HD 306414: Optical Counterpart to the Peculiar X-ray Transient IGR J11215-5952
We present high-resolution spectroscopy of HD 306414, optical counterpart to the hard X-ray transient IGR J11215-5952, an object belonging to the class of Supergiant Fast X-ray Transients. We derive a spectral type B0.5 Ia for HD 306414 and determine its stellar parameters from an atmosphere model fit to the spectrum. Our data, taken around the
