High-latitude supergiants: anomalies in the spectrum of LN Hya in 2010
Valentina Klochkova, Vladimir Panchuk
High-resolution echelle spectra taken with the 6-m telescope in 2003-2011 are used to study features of the optical spectrum and the velocity field in the atmosphere of the semireg…
Faint Companions of Isolated 2MIG Galaxies
V. E. Karachentseva, I. D. Karachentsev, O. V. Melnyk
We present the results of a search for companions around the isolated galaxies from the 2MIG catalog. Among 3227 2MIG galaxies we detected 125 objects with a total of 214 neighbors…
Survey of H-alpha emission from thirty nearby dwarf galaxies
S. S. Kaisin, I. D. Karachentsev, E. I. Kaisina
Measurements of the H-alpha flux from 30 neighboring dwarf galaxies are presented. After correction for absorption, these fluxes are used to estimate the star formation rate (SFR).…
AGILE detection of Cygnus X-3 γ-ray active states during the period mid-2009/mid-2010
A. Bulgarelli, M. Tavani, A. W. Chen +70
Cygnus X-3 (Cyg X-3) is a well-known microquasar producing variable emission at all wavelengths. Cyg X-3 is a prominent X-ray binary producing relativistic jets, and studying its h…
Galactic restrictions on iron production by various Types of supernovae
I. A. Acharova, Yu. N. Mishurov, V. V. Kovtyukh
We propose a statistical method for decomposition of contributions to iron production from various sources: supernovae Type II and the subpopulations of supernovae Type Ia -- promp…
Magnetic properties of three cool CP stars with strong fields
E. A. Semenko, L. A. Kichigina, E. Yu. Kuchaeva
The study of magnetic fields of cool chemically peculiar stars with effective temperatures less than 10 000 K is very important to understand the nature of their magnetism. We pres…
