The Inclination Angle and Mass of the Black Hole in XTE J1118+480
We have obtained optical and infrared photometry of the quiescent soft X-ray transient XTE J1118+480. In addition to optical and J-band variations, we present the first observed H- and Ks-bandExpand
GRO J0422+32: The Lowest Mass Black Hole?*
We have obtained optical and infrared photometry of the soft X-ray transient GRO J0422+32. From this photometry, we find a secondary star spectral type of M1, and an extinction of AV = 0.74 ± 0.09.Expand
THE INCLINATION OF THE SOFT X-RAY TRANSIENT A0620–00 AND THE MASS OF ITS BLACK HOLE
We analyze photometry of the soft X-ray transient A0620−00 spanning nearly 30 years, including previously published and previously unpublished data. Previous attempts to determine the inclination ofExpand
AN ASTROMETRIC CALIBRATION OF THE MV-PORB RELATIONSHIP FOR CATACLYSMIC VARIABLES BASED ON HUBBLE SPACE TELESCOPE FINE GUIDANCE SENSOR PARALLAXES
We present new, high-precision astrometric parallaxes for three cataclysmic variables: WZ Saggitae, YZ Cancri, and RU Pegasi, obtained using the Fine Guidance Sensors on the Hubble Space Telescope.Expand
A Multiwavelength, Multiepoch Study of the Soft X-Ray Transient Prototype, V616 Monocerotis (A0620−00)*
We have obtained optical and infrared photometry of the soft X-ray transient prototype V616 Mon (A0620-00). From this photometry, we find a spectral type of K4 for the secondary star in the system,Expand
The PTF Orion Project: a Possible Planet Transiting a T-Tauri Star
We report observations of a possible young transiting planet orbiting a previously known weak-lined T-Tauri star in the 7–10 Myr old Orion-OB1a/25-Ori region. The candidate was found as part of theExpand
The Mass of the Black Hole in XTE?J1118+480
We present contemporaneous, broadband, near-infrared spectroscopy (0.9-2.45 μm) and H-band photometry of the black hole X-ray binary, XTE J1118+480. We determined the fractional dilution of the NIRExpand
The exoplanet eccentricity distribution from Kepler planet candidates
The eccentricity distribution of exoplanets is known from radial velocity surveys to be divergent from circular orbits beyond 0.1 au. This is particularly the case for large planets where the radialExpand
The Low Quiescent X-Ray Luminosity of the Neutron Star Transient XTE J2123–058
We report on the first X-ray observations of the neutron star soft X-ray transient (SXT) XTE J2123-058 in quiescence made by the Chandra X-Ray Observatory and BeppoSAX, as well as contemporaneousExpand
Further evidence for variable synchrotron emission in XTE J1118+480 in outburst
We present simultaneous multicolor infrared and optical photometry of the black hole X-ray transient XTE J1118+480 during its short 2005 January outburst, supported by simultaneous X-rayExpand
