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…

TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70
Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…

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…
