Bayesian analysis of ages, masses, and distances to cool stars with non-LTE spectroscopic parameters

Aldo Serenelli, Maria Bergemann, Gregory Ruchti +1

For studies of Galactic evolution, the accurate characterization of stars in terms of their evolutionary stage and population membership is of fundamental importance. A standard ap…

Unveiling systematic biases in 1D LTE excitation-ionisation balance of Fe for FGK stars. A novel approach to determination of stellar parameters

Gregory R. Ruchti, Maria Bergemann, Aldo Serenelli +2

We present a comprehensive analysis of different techniques available for the spectroscopic analysis of FGK stars, and provide a recommended methodology which efficiently estimates…

Verifying asteroseismically determined parameters of Kepler stars using hipparcos parallaxes: self-consistent stellar properties and distances

V. Silva Aguirre, L. Casagrande, S. Basu +24

Accurately determining the properties of stars is of prime importance for characterizing stellar populations in our Galaxy. The field of asteroseismology has been thought to be par…

Seismic evidence for a rapidly rotating core in a lower-giant-branch star observed with Kepler

S. Deheuvels, R. A. Garcia, W. J. Chaplin +24

Rotation is expected to have an important influence on the structure and the evolution of stars. However, the mechanisms of angular momentum transport in stars remain theoretically…

The UBV(RI)c colors of the Sun

I. Ramirez, R. Michel, R. Sefako +6

Photometric data in the UBV(RI)c system have been acquired for 80 solar analog stars for which we have previously derived highly precise atmospheric parameters Teff, log g, and [Fe…
