Masses, Radii, and Orbits of Small Kepler Planets: The Transition From Gaseous to Rocky Planets
- G. Marcy, H. Isaacson, +100 authors D. Barrado
- Physics
- 16 January 2014
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise… Expand
Ages and fundamental properties of Kepler exoplanet host stars from asteroseismology
- V. S. Aguirre, G. Davies, +21 authors M. Lundkvist
- Physics
- 29 April 2015
We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual pulsation… Expand
Accurate fundamental parameters and detailed abundance patterns from spectroscopy of 93 solar-type Kepler targets
- H. Bruntt, S. Basu, +29 authors D. Sanderfer
- Physics
- 11 June 2012
We present a detailed spectroscopic study of 93 solar-type stars that are targets of the NASA/Kepler mission and provide detailed chemical composition of each target. We find that the overall… Expand
Stellar Spin-Orbit Misalignment in a Multiplanet System
- D. Huber, J. A. Carter, +32 authors J. Winn
- Physics, Medicine
- Science
- 16 October 2013
Misaligned Planets Stars with multiple coplanar planets have not been seen to show misalignments between the equatorial plane of the star and the orbital plane of the planets—a diagnostic of the… Expand
Testing Scaling Relations for Solar-like Oscillations from the Main Sequence to Red Giants Using Kepler Data
- D. Huber, T. Bedding, +29 authors J. Smith
- Physics, Mathematics
- 15 September 2011
We have analyzed solar-like oscillations in ~1700 stars observed by the Kepler Mission, spanning from the main sequence to the red clump. Using evolutionary models, we test asteroseismic scaling… Expand
Seismic constraints on the radial dependence of the internal rotation profiles of six Kepler subgiants and young red giants
- S. Deheuvels, G. Dougan, +25 authors M. Pinsonneault
- Physics
- 14 January 2014
Context. We still do not understand which physical mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed modes that contain the clear signature… Expand
AN ANCIENT EXTRASOLAR SYSTEM WITH FIVE SUB-EARTH-SIZE PLANETS
- T. Campante, T. Barclay, +38 authors T. White
- Physics
- 26 January 2015
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This implies… Expand
A uniform asteroseismic analysis of 22 solar-type stars observed by Kepler
- S. Mathur, T. Metcalfe, +39 authors B. Wohler
- Physics
- 13 February 2012
Asteroseismology with the Kepler space telescope is providing not only an improved characterization of exoplanets and their host stars, but also a new window on stellar structure and evolution for… Expand
Calibrating convective properties of solar-like stars in the Kepler field of view
- A. Bonaca, J. Tanner, +24 authors D. Caldwell
- Physics
- 11 July 2012
Stellar models generally use simple parameterizations to treat convection. The most widely used parameterization is the so-called mixing-length theory where the convective eddy sizes are described… Expand
Hot super-Earths stripped by their host stars
- M. Lundkvist, H. Kjeldsen, +26 authors T. White
- Physics, Medicine
- Nature communications
- 11 April 2016
Simulations predict that hot super-Earth sized exoplanets can have their envelopes stripped by photoevaporation, which would present itself as a lack of these exoplanets. However, this absence in the… Expand
