Probing the deep end of the Milky Way with Kepler asteroseismic analysis of 854 faint red giants misclassified as cool dwarfs. (2016)

Keywords : asteroseismology; methods data analysis; methods: numerical; stars: distances; stars: fundamental parameters; stars: oscillations , including pulsations

Abstract:Asteroseismology has proven to be an excellent tool to determine not only global stellar properties with good precision, but also to infer the stellar structure, dynamics, and evolution for a large sample of Kepler stars. Prior to the launch of the mission, the properties of Kepler targets were inferred from broadband photometry, leading to the Kepler Input Catalog (KIC). The KIC was later revised in the Kepler Star Properties Catalog, based on literature values and an asteroseismic analysis of stars that were unclassified in the KIC. Here, we present an asteroseismic analysis of 45400 stars that were classified as dwarfs in the Kepler Star Properties Catalog. We found that around 2% of the sample shows acoustic modes in the typical ...(more)

From the H14 catalog (Huber+, 2014, J/ApJS/211/2), we selected GKM dwarfs according to the following criteria: logg>=4.25 and Teff<=5500K. We also added a few tens of stars from the asteroseismic sample of solar-like stars from Chaplin et al. (2011ApJ...732...54C) where red-giant-like oscillations were detected. These additional stars have Teff>5500K.
