The Kepler characterization of the variability among A- and F-type stars. I. General overview
Asteroseismology - Stars: oscillations - Stars: variables: δ Scuti - Stars: fundamental parameters - binaries: general - Stars: statistics
2011/9/27
The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. We present a first general characterization of the pulsational behaviou...
SPIDER - V. Measuring Systematic Effects in Early-Type Galaxy Stellar Masses from Photometric SED Fitting
Measuring Systematic Effects Early-Type Galaxy Stellar Masses Photometric
2011/10/17
We present robust statistical estimates of the accuracy of early-type galaxy stellar masses derived from spectral energy distribution (SED) fitting as functions of various empirical and theoretical as...
Velocity Dispersions and Stellar Populations of the Most Compact and Massive Early-Type Galaxies at Redshift ~1
Velocity Dispersions Stellar Populations Most Compact Massive Early-Type Galaxies
2011/10/13
We present Gran-Telescopio-Canarias/OSIRIS optical spectra of 4 of the most compact and massive early-type galaxies in the Groth Strip Survey at redshift z~1, with effective radii Reff=0.5-2.4 kpc and...
Star formation history, double degenerates and type Ia supernovae in the thin disc
stars: white dwarfs − stars: evolution − stars: binaries: close − supernovae: general − Galaxy: evolution − Galaxy: structure
2011/9/27
We investigate the relation between the star formation history and the evolution of the double-degenerate (DD) population in the thin disc of the Galaxy, which we assume to have formed 10 Gyr before t...
Variability in the CoRoT photometry of three hot O-type stars. HD 46223, HD 46150 and HD 46966
stars: variables: general – stars: early-type – stars: individual: HD 46223 – stars: individual: HD 46150 – stars: individual: HD 46966 – stars: oscillations
2011/9/27
The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of the CoRoT mission has provided photometric data o...
