Lithium Abundances in the alpha Per Cluster
Suchitra C. Balachandran, Sushma V. Mallik, David L. Lambert
Lithium abundances are presented and discussed for 70 members of the 50 Myr old open cluster alpha Per. More than half of the abundances are from new high-resolution spectra. The L…
Infrared Echelle Spectroscopy of Palomar6 and M71
Jae-Woo Lee, Bruce W. Carney, Suchitra C. Balachandran
We present high-resolution infrared echelle spectroscopy for the globular clusters Palomar 6 and M71. Our mean heliocentric radial velocity of Palomar 6 is +180.6 +/- 3.2 km sec/s…
Chemical Abundances in Twelve Red Giants of the Large Magellanic Cloud from High-Resolution Infrared Spectroscopy
V. V. Smith, K. H. Hinkle, K. Cunha +10
High-resolution infrared spectra (R=50,000) have been obtained for twelve red-giant members of the LMC with the Gemini South 8.3-meter telescope plus Phoenix spectrometer. Quantita…
Membership, lithium, and metallicity in the young open clusters IC 2602 and IC 2391: enlarging the sample
S. Randich, R. Pallavicini, G. Meola +2
We present lithium abundances for ~50 X-ray selected candidate members of the 30-50 Myr old open clusters IC 2602 and IC 2391. These data enlarge and extend to cooler temperatures…
The Nature of the Lithium Rich Giants. Mixing episodes on the RGB and early-AGB
Corinne Charbonnel, Suchitra C. Balachandran
We present a critical analysis of the nature of the so-called Li-rich RGB stars. For a majority of the stars, we have used Hipparcos parallaxes to determine masses and evolutionary…
Stellar Iron Abundances at the Galactic Center
Solange V. Ramirez, Kristen Sellgren, John S. Carr +4
We present measurements of [Fe/H] for six M supergiant stars and three giant stars within 0.5 pc of the Galactic Center (GC) and one M supergiant star within 30 pc of the GC. The r…
The First Stellar Abundance Measurements in the Galactic Center: the M Supergiant IRS 7
John S. Carr, K. Sellgren, Suchitra C. Balachandran
The first measurement of the photospheric abundances in a star at the Galactic Center are presented. A detailed abundance analysis of the Galactic Center M2 supergiant IRS 7 was ca…
The Age of Gl879 and Fomalhaut
D. Barrado y Navascues, J. R. Stauffer, L. Hartmann +1
We estimate here the age of one of the prototypes of the Beta Pic-like stars, Fomalhaut, based on the properties of its common proper motion companion Gl879. By combining constrain…
