Detection of cesium in the atmosphere of the hot He-rich white dwarf HD 149499B
P. Chayer, C. Mendoza, M. Meléndez +2
We report the first detection of cesium (Z = 55) in the atmosphere of a white dwarf. Around a dozen absorption lines of Cs IV, Cs V, and Cs VI have been identified in the Far Ultra…
Seismic constraints on rotation of Sun-like star and mass of exoplanet
Laurent Gizon, Jérome Ballot, Eric Michel +32
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of observations of rotati…
Torsional Oscillations in a Global Solar Dynamo
P. Beaudoin, P. Charbonneau, E. Racine +1
We characterize and analyze rotational torsional oscillations developing in a large-eddy magnetohydrodynamical simulation of solar convection (Ghizaru, Charbonneau, and Smolarkiewi…
Precise Modeling of the Exoplanet Host Star and CoRoT Main Target HD 52265
M. E. Escobar, S. Théado S. Vauclair, J. Ballot +8
This paper presents a detailed and precise study of the characteristics of the Exoplanet Host Star and CoRoT main target HD 52265, as derived from asteroseismic studies. The result…
Hubble Space Telescope FUV Spectra of the Post-Common-Envelope Hyades Binary V471 Tauri
E. M. Sion, H. E. Bond, D. Lindler +4
We have carried out an analysis of the HST STIS archival spectra of the magnetic white dwarf in the Hyades eclipsing-spectroscopic, post-common envelope binary V471 Tauri, time res…
Accurate parameters of 93 solar-type Kepler targets
H. Bruntt, S. Basu, B. Smalley +29
We present a detailed spectroscopic study of 93 solar-type stars that are targets of the NASA/Kepler mission and provide detailed chemical composition of each target. We find that…
