Solving the mode identification problem in asteroseismology of F stars observed with Kepler

White, Timothy R.; Bedding, Timothy R.; Gruberbauer, Michael; Benomar, Othman; Stello, Dennis; Appourchaux, Thierry; Chaplin, William J.; Christensen-Dalsgaard, Jorgen; Elsworth, Yvonne P.; Garcia, Rafael A. (IOP Publishing Limited, 2012-06-01)

Asteroseismology of F-type stars has been hindered by an ambiguity in identification of their oscillation modes. The regular mode pattern that makes this task trivial in cooler stars is masked by increased line widths. The ...
Sounding open clusters: asteroseismic constraints from Kepler on the properties of NGC 6791 and NGC 6819

Gruberbauer, Michael; Basu, Sarbani; Grundahl, Frank; Stello, Dennis; Kallinger, T.; Hekker, Saskia; Mosser, Benoit; Garcia, Rafael A.; Mathur, Savita; Brogaard, Karsten (American Astronomical Society, 2011-03-01)

We present initial results on some of the properties of open clusters NGC 6791 and NGC 6819 derived from asteroseismic data obtained by NASA’s Kepler mission. In addition to estimating the mass, radius, and log g of stars ...
