Additional Ultracool White Dwarfs Found in the Sloan Digital Sky Survey
H. C. Harris, E. Gates, G. Gyuk +12
We identify seven new ultracool white dwarfs discovered in the Sloan Digital Sky Survey (SDSS). The SDSS photometry, spectra, and proper motions are presented, and additional BVRI…
Fraction of the radial velocity stable stars in the early observations of the Grid Giant Star Survey
Dmitry Bizyaev, Verne V. Smith
The GGSS is a partially-filled, all-sky survey to identify K-giant stars with low level of RV-variability. We study histograms of the radial velocity (RV) variability obtained in t…
Structural Parameters of Stellar Disks in Edge-on Galaxies from 2MASS Images
S. Mitronova, D. Bizyaev
We analyze the J, H, and Ks 2MASS images of 140 late-type edge-on galaxies selected from the RFGC catalog (which contains flat galaxies with major-to-minor axis ratio a/b > 7). The…
Modeling the star formation history in the ring galaxy Arp 10 with the help of spectral indices
D. Bizyaev, A. Moiseev, E. I. Vorobyov
We use long-slit spectra obtained with the 6-m telescope BTA (Russian Academy of Sciences) to investigate the history of star formation in the peculiar ring galaxy Arp 10. The radi…
The Space Interferometry Mission Astrometric Grid Giant-Star Survey. I. Stellar Parameters and Radial Velocity Variability
Dmitry Bizyaev, Verne V. Smith, Jose Arenas +7
We present results from a campaign of multiple epoch echelle spectroscopy of relatively faint (V = 9.5-13.5 mag) red giants observed as potential astrometric grid stars for the Spa…
Photometric observations of Grid Giant Star Survey candidates
D. Bizyaev, V. V. Smith, J. Arenas +1
We compare variability of radial velocity (RV) and brightness for a sample of red giants which were selected as candidates for the Grid Giant Star Survey (GGSS). The purpose of the…
