The mass of the black hole in GRS 1915+105: new constraints from IR spectroscopy
D. J. Hurley, P. J. Callanan, P. Elebert +1
GRS 1915+105 has the largest mass function of any Galactic black hole system, although the error is relatively large. Here we present spectroscopic analysis of medium-resolution IR…
Optical spectroscopy and Doppler tomography of Cygnus X-2
P. Elebert, P. J. Callanan, M. A. P. Torres +1
We present phase resolved optical spectroscopy and Doppler tomography of V1341 Cygni, the optical counterpart to the neutron star low mass X-ray binary Cygnus X-2. We derive a radi…
Optical spectroscopy and photometry of SAX J1808.4-3658 in outburst
P. Elebert, M. T. Reynolds, P. J. Callanan +8
We present phase resolved optical spectroscopy and photometry of V4580 Sagittarii, the optical counterpart to the accretion powered millisecond pulsar SAX J1808.4-3658, obtained du…
Optical Photometry and Spectroscopy of the Accretion-Powered Millisecond Pulsar HETE J1900.1-2455
P. Elebert, P. J. Callanan, A. V. Filippenko +4
We present phase resolved optical photometry and spectroscopy of the accreting millisecond pulsar HETE J1900.1-2455. Our R-band light curves exhibit a sinusoidal modulation, at clo…
