The connection between stellar granulation and oscillation as seen by the Kepler mission

Kallinger, T.; De Ridder, J.; Hekker, S.; Mathur, S.; Mosser, B.; Gruberbauer, Michael; Garcia, R. A.; Karoff, C.; Ballot, J. (EDP Sciences, 2014-10)

Context. The long and almost continuous observations by Kepler show clear evidence of a granulation background signal in a large sample of stars, which is interpreted as the surface manifestation of convection. It has been ...
Observations of intensity fluctuations attributed to granulation and faculae on Sun-like stars from the Kepler mission

Gruberbauer, Michael; Karoff, C.; Campante, T. L.; Ballot, J.; Kallinger, T.; Garcia, R. A.; Caldwell, D. A.; Christiansen, J. L.; Kinemuchi, K. (American Astronomical Society, 2013-04-10)

Sun-like stars show intensity fluctuations on a number of timescales due to various physical phenomena on their surfaces. These phenomena can convincingly be studied in the frequency spectra of these stars—while the strongest ...
