Chemical Abundances of Luminous Cool Stars in the Galactic Center from High-Resolution Infrared Spectroscopy
We present chemical abundances in a sample of luminous cool stars located within 30 pc of the Galactic center. Abundances of carbon, nitrogen, oxygen, calcium, and iron were derived fromExpand

Really Cool Stars and the Star Formation History at the Galactic Center
We present ?/?? = 550-1200 near-infrared H and K spectra for a magnitude-limited sample of 79 asymptotic giant branch and cool supergiant stars in the central ?5 pc (diameter) of the Galaxy. We use aExpand

The Frequency of Barred Spiral Galaxies in the Near-Infrared*
We have determined the fraction of barred galaxies in the H-band for a statistically well-defined sample of 186 spirals drawn from the Ohio State University Bright Spiral Galaxy Survey. We find 56%Expand

Near- and Mid-Infrared Photometry of the Pleiades and a New List of Substellar Candidate Members
We make use of new near- and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously published photometry toExpand

A catalog of X-ray point sources from two megaseconds of Chandra observations of the Galactic center
We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2 ◦ × 0. 8 field around the Galactic center. This enlarges the number of known X-ray sources in the region by aExpand

CHARACTERIZING THE VARIABILITY OF STARS WITH EARLY-RELEASE KEPLER DATA
We present a variability analysis of the early-release first quarter of data publicly released by the Kepler project. Using the stellar parameters from the Kepler Input Catalog, we have separated theExpand

Carbon Stars in the Hamburg/ESO Survey: Abundances*
We have carried out a detailed abundance analysis using high-dispersion spectra from HIRES at Keck for a sample of 16 carbon stars found among candidate extremely metal-poor (EMP) stars from theExpand

Near-Infrared and Optical Morphology of Spiral Galaxies
We announce the initial release of data from the Ohio State University (OSU) Bright Spiral Galaxy Survey, a BVRJHK imaging survey of a well-defined sample of 205 bright, nearby spiral galaxies. WeExpand

An Accurate, Easy-To-Use Abundance Scale for Globular Clusters Based on 2.2 Micron Spectra of Giant Stars
We present a new method for the determination of [Fe/H] for globular clusters. This method is based on moderate-resolution (~1500) near-IR spectroscopy in the K band of six to 10 of the brightestExpand
