VLT/FORS2 observations of four high-luminosity ULX candidates
M. Heida, P. G. Jonker, M. A. P. Torres +4
We obtained VLT/FORS2 spectra of the optical counterparts of four high-luminosity (L_X >= 10^40 erg/s) ULX candidates from the catalog of Walton (2011). We first determined accurat…

IGR J19308+0530: Roche lobe overflow on to a compact object from a donor 1.8 times as massive
E. M. Ratti, T. F. J. van Grunsven, M. A. P. Torres +6
We present phase-resolved spectroscopy and photometry of the optical counterpart to the X-ray binary IGR J19308+0530. Ellipsoidal modulations in the light curve show that the F-typ…
