Oscillation mode linewidths of main-sequence and subgiant stars observed by Kepler

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…

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…
Characterization of the power excess of solar-like oscillations in red giants with Kepler
B. Mosser, Y. Elsworth, S. Hekker +15
We aim to describe the oscillation power excess observed in Kepler red giants, and to investigate empirical scaling relations governing these parameters. From these scalings relati…
Seismic analysis of four solar-like stars observed during more than eight months by Kepler
S. Mathur, T. L. Campante, R. Handberg +41
Having started science operations in May 2009, the Kepler photometer has been able to provide exquisite data of solar-like stars. Five out of the 42 stars observed continuously dur…
Investigating the properties of granulation in the red giants observed by Kepler
S. Mathur, S. Hekker, R. Trampedach +18
More than 1000 red giants have been observed by NASA/Kepler mission during a nearly continuous period of ~ 13 months. The resulting high-frequency resolution (< 0.03 muHz) allows u…
Replicated Echelle Diagrams in Asteroseismology: A Tool for Studying Mixed Modes and Avoided Crossings
Timothy R. Bedding
In oscillating stars, mixed modes have p-mode character in the envelope and g-mode character in the core. They are observed in subgiants and red giants, in which the large density…

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…

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…
