The Stellar Observations Network Group (SONG) is an international network project aiming to place eight 1-m robotic telescopes around the globe, with the primary objectives of stud…
Oscillation mode linewidths of main-sequence and subgiant stars observed by Kepler
T. Appourchaux, O. Benomar, M. Gruberbauer +20
Solar-like oscillations have been observed by {\it Kepler} and CoRoT in several solar-type stars. We study the variations of stellar p-mode linewidth as a function of effective tem…
Fast core rotation in red-giant stars revealed by gravity-dominated mixed modes
Paul G. Beck, Josefina Montalban, Thomas Kallinger +21
When the core hydrogen is exhausted during stellar evolution, the central region of a star contracts and the outer envelope expands and cools, giving rise to a red giant, in which…
Kepler-21b: A 1.6REarth Planet Transiting the Bright Oscillating F Subgiant Star HD 179070
Steve B. Howell, Jason F. Rowe, Stephen T. Bryson +63
We present Kepler observations of the bright (V=8.3), oscillating star HD 179070. The observations show transit-like events which reveal that the star is orbited every 2.8 days by…
Fundamental properties of five Kepler stars using global asteroseismic quantities and ground-based observations

Kepler asteroseismology of red-giant stars
J. Christensen-Dalsgaard
The Kepler mission, launched in March 2009, has revolutionized asteroseismology, providing detailed observations of thousands of stars. This has allowed in-depth analysis of stars…
On a new theoretical calibration of the Stroemgren hk metallicity index: NGC6522 as a first test case
A. Calamida, G. Bono, C. Corsi +11
We present a new theoretical calibration of the Stroemgren metallicity index hk by using alpha-enhanced evolutionary models transformed into the observational plane by using atmosp…
Solar-like oscillations in the G9.5 subgiant beta Aquilae
E. Corsaro, F. Grundahl, S. Leccia +3
An interesting asteroseismic target is the G9.5 IV solar-like star beta Aql. This is an ideal target for asteroseismic investigations, because precise astrometric measurements are…
Asteroseismic diagrams from a survey of solar-like oscillations with Kepler
Timothy R. White, Timothy R. Bedding, Dennis Stello +30
Photometric observations made by the NASA Kepler Mission have led to a dramatic increase in the number of main-sequence and subgiant stars with detected solar-like oscillations. We…
A Revised Effective Temperature Scale for the Kepler Input Catalog
Marc H. Pinsonneault, Deokkeun An, Joanna Molenda-Żakowicz +3
We present a catalog of revised effective temperatures for stars observed in long-cadence mode in the Kepler Input Catalog (KIC). We use SDSS griz filters tied to the fundamental t…
Ensemble Asteroseismology of Solar-Type Stars with the NASA Kepler Mission
W. J. Chaplin, H. Kjeldsen, J. Christensen-Dalsgaard +56
In addition to its search for extra-solar planets, the NASA Kepler Mission provides exquisite data on stellar oscillations. We report the detections of oscillations in 500 solartyp…
Asteroseismology of old open clusters with Kepler: direct estimate of the integrated RGB mass loss in NGC6791 and NGC6819
A. Miglio, K. Brogaard, D. Stello +21
Mass loss of red giant branch (RGB) stars is still poorly determined, despite its crucial role in the chemical enrichment of galaxies. Thanks to the recent detection of solar-like…
The excitation of solar-like oscillations in a delta Scuti star by efficient envelope convection
V. Antoci, G. Handler, T. L. Campante +21
Delta Scuti (delta Sct) stars are opacity-driven pulsators with masses of 1.5-2.5M, their pulsations resulting from the varying ionization of helium. In less massive star…
Testing Scaling Relations for Solar-Like Oscillations from the Main Sequence to Red Giants using Kepler Data
D. Huber, T. R. Bedding, D. Stello +29
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 asteros…
Calculating asteroseismic diagrams for solar-like oscillations

With the success of the Kepler and CoRoT missions, the number of stars with detected solar-like oscillations has increased by several orders of magnitude, for the first time we are…
Granulation in Red Giants: observations by the Kepler mission and 3D convection simulations
S. Mathur, S. Hekker, R. Trampedach +18
The granulation pattern that we observe on the surface of the Sun is due to hot plasma from the interior rising to the photosphere where it cools down, and descends back into the i…
