Characterizing Kepler Asteroseismic Targets
space vehicles Kepler – stars abundances – stars fundamental param-eters – stars binaries: spectroscopic
2010/11/11
Stellar structure and evolution can be studied in great detail by asteroseismic methods, provided data of high precision are available. We determine the effective temperature (Teff), surface gravity (...
Mode width fitting with a simple bayesian approach. Application to CoRoT targets HD 181420 and HD 49933

2010/11/15
Aims. We investigate the asteroseismology of two solar-like targets as observed with the CoRoT satellite, with particular attention paid to the mode fitting. HD 181420 and HD 49933 are typical CoRoT s...
Parallaxes of Southern Extremely Cool objects - I: Targets, Proper motions and first results
Parallaxes of Southern Extremely Cool objects Proper motions first results
2010/11/11
We present results from the PARallaxes of Southern Extremely Cool objects (PARSEC)program, an observational program begun in April 2007 to determine parallaxes for 122 L and 28 T southern hemisphere d...
