Parent Stars of Extrasolar Planets. VIII. Chemical Abundances for 18 Elements in 31 Stars
Guillermo Gonzalez, Chris Laws
We present the results of detailed spectroscopic abundance analyses for 18 elements in 31 nearby stars with planets. The resulting abundances are combined with other similar studie…
A Re-evaluation of the Super Li-rich Star in NGC 6633
C. Laws, G. Gonzalez
We present a new abundance analysis of the super Li-rich star J37 and a comparison star in NGC 6633. We confirm the result of Deliyannis et al. that J37 has a Li abundance well abo…
Parent Stars of Extrasolar Planets VII: New Abundance Analyses of 30 Systems
Chris Laws, Guillermo Gonzalez, Kyle M. Walker +4
The results of new spectroscopic analyses of 30 stars with giant planet and/or brown dwarf companions are presented. Values for Teff and [Fe/H] are used in conjunction with Hipparc…
The Microlensing Event MACHO-99-BLG-22/OGLE-1999-BUL-32: An Intermediate Mass Black Hole, or a Lens in the Bulge
D. P. Bennett, A. C. Becker, J. J. Calitz +5
We present an re-analysis of the longest timescale gravitational microlensing event discovered to date: MACHO-99-BLG-22/OGLE-1999-BUL-32, which was discovered by both the MACHO and…
A Differential Spectroscopic Analysis of 16 Cygni A and B
Chris Laws, Guillermo Gonzalez
We utilize high-resolution, high signal-to-noise spectra to perform a differential analysis of Fe abundances in the common proper-motion pair 16 Cyg A and B. We confirm that both s…
Parent Stars of Extrasolar Planets VI: Abundance Analyses of 20 New Systems
G. Gonzalez, C. Laws, S. Tyagi +1
The results of new spectroscopic analyses of 20 recently reported extrasolar planet parent stars are presented. The companion of one of these stars, HD 10697, has recently been sho…
