Using adaptive optics at the Gemini North telescope, we have obtained a K-band spectrum of the star near the center of the luminous Galactic center bow shock IRS 8, as well as a spectrum of the bow shock itself. The stellar spectrum contains emission and absorption lines characteristic of an O5-O6 giant or supergiant. The wind from such a star is fully capable of producing the observed bow shock. However, both the early spectral type and the apparently young age of the star, if it is single… 
M-BAND SPECTRA OF DUST-EMBEDDED SOURCES AT THE GALACTIC CENTER
The goal of the present paper is to investigate the circumstellar material around the brightest dust-enshrouded sources in the central stellar cluster of the Milky Way. Observations have been carried
Compact mid-IR sources east of Galactic Center source IRS5
Aims. Mid-infrared observations of the Galactic Center show among the extended mini-spiral a number of compact sources. Their nature is of interest because they represent an interaction of luminous
Composition of the galactic center star cluster. Population analysis from adaptive optics narrow ban
Context. The GC is the closest galactic nucleus, offering the unique possibility of studying the population of a dense stellar cluster surrounding an SMBH. Aims. The goals of this work are to develop
Metallicity studies of the Galactic center: evidence for a top-heavy star formation history?
Abstract The Galactic center (GC) region hosts three of the most massive resolved young clusters in the Local Group and constitutes a test bed for studying the star formation history of the region
KMOS view of the Galactic Centre I: Young Stars are centrally concentrated
The Galactic centre hosts a crowded, dense nuclear star cluster with a half-light radius of 4 pc. Most of the stars in the Galactic centre are cool late-type stars, but there are also >100 hot
Properties of bow-shock sources at the Galactic center
There are an enigmatic population of massive stars around the Galactic Center (GC) that were formed some Ma ago. A fraction of these stars has been found to orbit the supermassive black hole, SgrA*,
A peek behind the dusty curtain: KS-band polarization photometry and bow shock models of the Galactic center source IRS 8
Context. IRS 8 offers the possibility to study unique bow shock properties and polarization features in the dusty environment at the Galactic center. Aims. We aim to gain insight into the properties
INTRINSICALLY POLARIZED STARS AND IMPLICATION FOR STAR FORMATION IN THE CENTRAL PARSEC OF OUR GALAXY
We have carried out adaptive-optics assisted observations at the Subaru Telescope and have found 11 intrinsically polarized sources in the central parsec of our Galaxy. They are selected from 318
The Chemical Abundances in the Galactic Center from the Atmospheres of Red Supergiants
The Galactic center (GC) has experienced a high degree of recent star-forming activity, as evidenced by the large number of massive stars currently residing there. The relative abundances of chemical
METALLICITY IN THE GALACTIC CENTER: THE QUINTUPLET CLUSTER
We present a measurement of metallicity in the Galactic center Quintuplet cluster made using quantitative spectral analysis of two luminous blue variables (LBVs). The analysis employs line-blanketed
