Star Formation in Outer Rings of S0 galaxies. V. UGC 4599 -- an S0 with gas probably accreted from a filament
O. Sil'chenko, A. Moiseev, D. Oparin +2
Though S0 galaxies are usually thought to be `red and dead', they often demonstrate weak star formation organised in ring structures and located in their outer disks. We try to cla…
Stellar feedback impact on the ionized gas kinematics in the dwarf galaxy Sextans A
Ivan S. Gerasimov, Oleg V. Egorov, Tatiana A. Lozinskaya +2
Feedback from massive stars shapes the ISM and affects the evolution of galaxies, but its mechanisms acting at the small scales ( pc) are still not well constrained observ…
Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631
Y. -Z. Cai, A. Pastorello, M. Fraser +73
We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…
Search for LBVs in the Local Volume galaxies: study of four stars in NGC 4449
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +8
We continue to search for LBV stars in galaxies outside the Local Group. In this work, we have investigated four luminous stars in NGC 4449. Multiple spectral observations carried…
Search for LBVs in the Local Volume galaxies: study of two stars in NGC 1156
Y. Solovyeva, A. Vinokurov, N. Tikhonov +7
We continue the search for luminous blue variables (LBVs) in Local Volume galaxies in order to study their fundamental parameters. In this paper, we report the discovery of two new…
