Kepler-7b: A Transiting Planet with Unusually Low Density
David W. Latham, William J. Borucki, David G. Koch +18
We report the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, Mp = 0.43 Mj, but the radius is f…
Initial Characteristics of Kepler Short Cadence Data
Ronald L. Gilliland, J. M. Jenkins, W. J. Borucki +12
The Kepler Mission offers two options for observations -- either Long Cadence (LC) used for the bulk of core mission science, or Short Cadence (SC) which is used for applications s…
Kepler Asteroseismology Program: Introduction and First Results
Ronald L. Gilliland, T. M. Brown, J. Christensen-Dalsgaard +32
Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observationsof normal modes of oscillation. The te…
Asteroseismic Investigation of Known Planet Hosts in the Kepler Field
J. Christensen-Dalsgaard, H. Kjeldsen, T. M. Brown +7
In addition to its great potential for characterizing extra-solar planetary systems the Kepler mission is providing unique data on stellar oscillations. A key aspect of Kepler aste…
Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819
Dennis Stello, Sarbani Basu, Hans Bruntt +49
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theor…
Identification and properties of the photospheric emission in GRB090902B
F. Ryde, M. Axelsson, B. B. Zhang +19
The Fermi Gamma-ray Space Telescope observed the bright and long GRB090902B, lying at a redshift of z = 1.822. Together the Large Area Telescope (LAT) and the Gamma-ray Burst Monit…
