Very gas-rich extremely metal-poor blue void dwarfs
S. Pustilnik, Y. Perepelitsyna, A. Kniazev +2
Half-dozen of extreme representatives of void dwarf galaxy population were found in our study of evolutionary status of a hundred galaxies in the nearby Lynx-Cancer void. They are…
Two circumstellar nebulae discovered with the Wide-field Infrared Survey Explorer and their massive central stars
V. V. Gvaramadze, A. Y. Kniazev, N. Castro +1
We report the discovery of two mid-infrared nebulae in the northern hemisphere with the Wide-field Infrared Survey Explorer and the results of optical spectroscopy of their central…
CPD-64 2731: a massive spun-up and rejuvenated high-velocity runaway star
V. V. Gvaramadze, O. V. Maryeva, A. Y. Kniazev +4
We report the results of our study of the high-velocity (\approx160 km/s) runaway O star CPD-64 2731 and its associated horseshoe-shaped nebula discovered with the Wide-field Infra…
Study of galaxies in the Eridanus void. Sample and oxygen abundances
A. Y. Kniazev, E. S. Egorova, S. A. Pustilnik
We present a sample of 66 galaxies belonging to the equatorial part (Dec.= -7, +7) of the large so called Eridanus void (after Fairall 1998). The void galaxies are selected…
The structure of large-scale stellar disks in cluster lenticular galaxies
Olga K. Sil'chenko, Alexei Yu. Kniazev, Ekaterina M. Chudakova
By obtaining imaging data in two photometric bands for 60 lenticular galaxies - members of 8 southern clusters - with the Las Cumbres Observatory one-meter telescope network, we ha…
Line identification and photometric history of the hot post-AGB star Hen 3-1013 (IRAS 14331-6435)
V. P. Arkhipova, M. Parthasarathy, N. P. Ikonnikova +4
We present a study of the high-resolution optical spectrum for the hot post-asymptotic giant branch (post-AGB) star, Hen 3-1013, identified as the optical counterpart of the infrar…
