Kepler Asteroseismology Program: Introduction and First Results
Ronald L. Gilliland, T. M. Brown, J. Christensen-Dalsgaard +32
Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observationsof normal modes of oscillation. The te…
A substellar component orbiting the F-star 30 Ari B
E. W. Guenther, M. Hartmann, M. Esposito +3
CONTEXT: Most current radial velocity planet search programs have concentrated on stars of one solar mass. Our knowledge on the frequency of giant planets and brown dwarf companion…
Asteroseismic modelling of the solar-like star Hydri
G. Doğan, I. M. Brandão, T. R. Bedding +3
We present the results of modelling the subgiant star Hydri using the seismic observational constraints. We have computed several grids of stellar evolutionary tracks using Aar…
The radius and effective temperature of the binary Ap star beta CrB from CHARA/FLUOR and VLT/NACO observations
H. Bruntt, P. Kervella, A. Merand +14
The prospects for using asteroseismology of rapidly oscillating Ap (roAp) stars are hampered by the large uncertainty in fundamental stellar parameters. Results in the literature f…
The HARPS search for southern extra-solar planets. XX. Planets around the active star BD-08:2823
G. Hebrard, S. Udry, G. Lo Curto +13
We report the detection of a planetary system around BD-08:2823, that includes at least one Uranus-mass planet and one Saturn-mass planet. This discovery serendipitously originates…
Observational signatures for depletion in the Spite plateau: solving the cosmological Li discrepancy?
J. Melendez, L. Casagrande, I. Ramirez +2
We present Li abundances for 73 stars in the metallicity range -3.5 < [Fe/H] < -1.0 using improved IRFM temperatures (Casagrande et al. 2010) with precise E(B-V) values obtained mo…
