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…
Long-slit and Fabry-Perot spectroscopy of collisional ring galaxy Arp 10
A. V. Moiseev, D. V. Bizyaev, E. I. Vorobyov
We present results of Fabry-Perot and long-slit spectroscopy of the peculiar galaxy Arp 10. The ionized gas velocity field shows evidence for significant radial motions in both out…
