A closely packed system of low-mass, low-density planets transiting Kepler-11
When an extrasolar planet passes in front of (transits) its star, its radius can be measured from the decrease in starlight and its orbital period from the time between transits. Multiple planetsExpand

Optical Observations of GRO J1655?40 in Quiescence. I. A Precise Mass for the Black Hole Primary
We report photometric and spectroscopic observations of the black hole binary GRO J1655-40 in complete quiescence. In contrast to the 1995 photometry, the light curves from 1996 are almost completelyExpand

THE MASS OF THE BLACK HOLE IN CYGNUS X-1
Cygnus X-1 is a binary star system that is comprised of a black hole and a massive giant companion star in a tight orbit. Building on our accurate distance measurement reported in the precedingExpand

THE TRIGONOMETRIC PARALLAX OF CYGNUS X-1
We report a direct and accurate measurement of the distance to the X-ray binary Cygnus X-1, which contains the first black hole to be discovered. The distance of 1.86{sup +0.12}{sub -0.11} kpc wasExpand

Kepler-16: A Transiting Circumbinary Planet
An exoplanet has been observed, comparable in size and mass to Saturn, that orbits a pair of stars. We report the detection of a planet whose orbit surrounds a pair of low-mass stars. Data from theExpand

KEPLER ECLIPSING BINARY STARS. I. CATALOG AND PRINCIPAL CHARACTERIZATION OF 1879 ECLIPSING BINARIES IN THE FIRST DATA RELEASE
The Kepler space mission is devoted to finding Earth-size planets orbiting other stars in their habitable zones. Its large, 105 deg2 field of view features over 156,000 stars that are observedExpand

The optical light curves of Cygnus X-2 (V1341 Cyg) and the mass of its neutron star
We present U, B and V light curves (taken from the literature) of the low-mass X-ray binary Cygnus X-2. We show that the most significant photometric periods seen in the B and V light curves areExpand

Dynamical Evidence for a Black Hole in the Microquasar XTE J1550-564
Optical spectroscopic observations of the companion star (type G8 IV to K4 III) in the microquasar system XTE J1550-564 reveal a radial velocity curve with a best-fitting spectroscopic period of PspExpand

Optical and Infrared Photometry of the Microquasar GRO J1655-40 in Quiescence
We present BVIJK photometry of the black hole candidate GRO J1655-40 in full quiescence. We report a refined orbital period of 2.62191 ± 0.00020 days. The light curves are dominated by ellipsoidalExpand
