XO-2b: a Prograde Planet with a Negligible Eccentricity, and an Additional Radial Velocity Variation
Norio Narita, Teruyuki Hirano, Bun'ei Sato +4
We present precise radial velocities of XO-2 taken with the Subaru HDS, covering two transits of XO-2b with an interval of nearly two years. The data suggest that the orbital eccen…
Further Observations of the Tilted Planet XO-3: A New Determination of Spin-Orbit Misalignment, and Limits on Differential Rotation
Teruyuki Hirano, Norio Narita, Bun'ei Sato +5
We report on observations of the Rossiter-McLaughlin (RM) effect for the XO-3 exoplanetary system. The RM effect for the system was previously measured by two different groups, but…
Exploring the Neutrino Mass Hierarchy Probability with Meteoritic Supernova Material, ν-Process Nucleosynthesis, and θ13 Mixing
G. J. Mathews, T. Kajino, W. Aoki +2
There is recent evidence that some SiC X grains from the Murchison meteorite may contain supernova-produced ν-process 11B and or 7Li encapsulated in the grains. The synthesis of 11…
Detailed Chemical Abundances of Four Stars in the Unusual Globular Cluster, Palomar 1
Charli M. Sakari, Kim A. Venn, Mike Irwin +3
Detailed chemical abundances for twenty one elements are presented for four red giants in the anomalous outer halo globular cluster Palomar 1 ( kpc, kpc…
Enrichment of Heavy Elements in the red giant S15-19 in the Sextans Dwarf Spheroidal Galaxy
Satoshi Honda, Wako Aoki, Nobuo Arimoto +1
We determined chemical abundances of the Extremely Metal-Poor (EMP) star S15-19 ([Fe/H]=-3.0) in the Sextans dwarf galaxy. While heavy neutron-capture elements (e.g., Ba) are gener…
Carbon-Enhanced Metal-Poor Stars in the Inner and Outer Halo Components of the Milky Way
D. Carollo, T. C. Beers, J. Bovy +6
(Abridged) Carbon-enhanced metal-poor (CEMP) stars in the halo components of the Milky Way are explored, based on accurate determinations of the carbon-to-iron ([C/Fe]) abundance r…
