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…
Bending instability in galaxies: the stellar disk thickness and the mass of spheroidal component
N. V. Tyurina, A. V. Khoperskov, D. V. Bizyaev
We present results of numerical N-body simulations of a galactic stellar disk embedded into a spherical dark halo. The non-linear dynamics of bending instabilities developing in th…
The galactic disk thickness and the mass of the spherical component
D. Bizyaev, A. Khoperskov, N. Tiurina
We present results of numerical modeling made for the galactic stellar disk embedded in the spherical halo. The non-linear dynamics of bending instabilities developed in the disk i…
Surface photometry of LSB edge-on galaxies
Dmitry Bizyaev, Serafim Kajsin
We present results of surface photometry for eleven edge-on galaxies observed with the 6-m telescope at the Special Astrophysical Observatory of the Russian Academy of Sciences. Th…
