Is the plateau state in GRS 1915+105 equivalent to canonical hard states?
Pieter van Oers, Sera Markoff, Dipankar Maitra +7
GRS1915+105 is a very peculiar black hole binary that exhibits accretion-related states that are not observed in any other stellar-mass black hole system. One of these states, howe…
A multicolor near-infrared study of the dwarf nova IP Peg
T. Ribeiro, R. Baptista, E. T. Harlaftis +2
We report the analysis of light curves of the eclipsing dwarf nova IP Peg in quiescence. The light curves are dominated by the ellipsoidal variation of the mass-donor sta…
ULTRACAM: an ultra-fast, triple-beam CCD camera for high-speed astrophysics
V. S. Dhillon, T. R. Marsh, M. J. Stevenson +15
ULTRACAM is a portable, high-speed imaging photometer designed to study faint astronomical objects at high temporal resolutions. ULTRACAM employs two dichroic beamsplitters and thr…
SW Sextantis stars: the dominant population of CVs with orbital periods between 3-4 hours
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +15
[Abridged] We present time-series optical photometry of five new CVs identified by the Hamburg Quasar Survey. The eclipses observed in HS 0129+2933, HS 0220+0603, and HS 0455+8315…
Dwarf novae in the Hamburg Quasar Survey: Rarer than expected
A. Aungwerojwit, B. T. Gaensicke, P. Rodriguez-Gil +12
We report the discovery of five new dwarf novae from the Hamburg Quasar Survey (HQS), and discuss the properties of the sample of dwarf novae in the HQS. The orbital periods of the…
XTE J1118+480: A Metal-Rich Black Hole Binary in the Galactic Halo
Jonay I. Gonzalez Hernandez, Rafael Rebolo, Garik Israelian +3
We present medium-resolution optical spectra of the secondary star in the high Galactic latitude black hole X-ray binary XTE J1118+480 and determine the abundance of Mg, Al, Ca, Fe…
