We report on 75 mas resolution, near-IR imaging spectroscopy within the central 30 lt-days of the Galactic center, taken with the new adaptive optics-assisted integral-field spectrometer SINFONI on the ESO VLT. To a limiting magnitude of K ~ 16, 9 of 10 stars in the central 0.″4, and 13 of 17 stars out to 0.″7 from the central black hole have spectral properties of B0-B9 main-sequence stars. Based on the 2.1127 μm He I line width, all brighter early-type stars have normal rotation velocities… 

EVIDENCE FOR WARPED DISKS OF YOUNG STARS IN THE GALACTIC CENTER

TLDR
It is shown that half of the W-R/O stars are compatible with being members of a clockwise rotating system, which is compatible with a coherent structure such as stellar filaments, streams, small clusters or possibly a disk in a dissolving state.

We report the definite spectroscopic identification of ≃40 OB supergiants, giants, and main-sequence stars in the central parsec of the Galaxy. Detection of their absorption lines has become possible

Twelve Years of Spectroscopic Monitoring in the Galactic Center: The Closest Look at S-stars near the Black Hole

We study the young S-stars within a distance of 0.04 pc from the supermassive black hole in the center of our Galaxy. Given how inhospitable the region is for star formation, their presence is more

Spectroscopic Detection of a Cusp of Late-type Stars around the Central Black Hole in the Milky Way

In a dynamically relaxed cluster around a massive black hole a dense stellar cusp of old stars is expected to form. Previous observations showed a relative paucity of red giant stars within the

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

Orbits and Origins of the Young Stars in the Central Parsec

We present new proper motions for the massive, young stars at the Galactic Center, based on 10 years of diffraction limited data from the Keck telescopes. Our proper motion measurements now have

The nature of IRS 13N: YSOs in the central parsec of the galaxy?

IRS13N is a small (~0.25'' projected diameter), compact group of sources located ~3.5'' from Sgr A* and ~0.5'' north from the well known IRS 13E cluster. The sources exhibit strong infrared excess

ORIGIN OF THE GALACTIC CENTER S-STARS: GRAVITATIONAL TORQUES FROM LIN–SHU-TYPE SPIRAL DENSITY WAVES

The supermassive ∼4 × 106 M☉ black hole at the Galactic center is surrounded by a parsec-scale star disk, with several thousands of dynamically relaxed, evolved, late-type CO absorption line stars
