Post-AGB candidate IRAS 02143+5852: Cepheid-like variability, three-layer circumstellar dust envelope and spectral features
N. P. Ikonnikova, M. A. Burlak, A. V. Dodin +8
We present the results of multicolour photometry, spectroscopic analysis and spectral energy distribution (SED) modelling for the post-AGB candidat…
The Post-AGB Star IRAS 07253-2001: Pulsations, Long-Term Brightness Variability and Spectral Peculiarities
N. P. Ikonnikova, M. A. Burlak, A. V. Dodin +5
The observations and comprehensive study of intermediate initial mass stars at the late stages of evolution, and after the asymptotic giant branch (AGB) in particular, are of cruci…
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…
New Luminous Blue Variable Candidates in NGC 4736
Y. Solovyeva, A. Vinokurov, S. Fabrika +8
We have found three new LBV candidates in the star-forming galaxy NGC 4736. They show typical well-known LBV spectra, broad and strong hydrogen lines, He I lines, many Fe II lines,…
