Photometric and Spectral Evolution of the Symbiotic Nova HM Sagittae since 2003
N. P. Ikonnikova, V. I. Shenavrin, G. V. Komissarova +2
We present photometric and spectral monitoring of the symbiotic system HM Sge, which consists of a Mira variable with a dust shell and a hot white dwarf ionizing the surrounding ga…
IRAS 22272+5435 (V354 Lac): Multicolor Photometry of a Variable Carbon-rich post-AGB Star and a Dust Formation Episode
N. P. Ikonnikova, V. I. Shenavrin, G. V. Komissarova +1
We present new UBV photometric observations (2009-2024) of the carbon-rich post-AGB star IRAS 22272+5435 (V354 Lac), combined with our data spanning over 30 years (1991-2024). The…
Disk in the circumstellar envelope of carbon Mira V Cygni
Boris S. Safonov, Sergey G. Zheltoukhov, Andrey M. Tatarnikov +2
AGB stars are the primary source of dust and complex molecules in the interstellar medium. The determination of outflow parameters is often hindered by the unknown geometry of the…
The long-period spectroscopic orbit and dust creation in the Wolf-Rayet binary system WR 125
Noel D. Richardson, Andrea R. Daly, Peredur M. Williams +8
Several long-period binaries with a carbon-rich Wolf-Rayet star and an O star produce dust in their wind collisions. In eccentric binaries, this is seen most strongly near periastr…
Recurrent Symbiotic Nova T Coronae Borealis Before Outburst
N. A. Maslennikova, A. M. Tatarnikov, A. A. Tatarnikova +5
The results of photometric and spectral observations of T CrB obtained in a wide range of wavelengths in 2011-2023 are presented. We use the near-IR light curves to determine a new…
FORCASTing the spectroscopic dust properties of the WC+O binary WR137 with SOFIA
Megan J. Peatt, Noel D. Richardson, Peredur M. Williams +5
WR 137 (HD 192641) is a binary system consisting of a carbon-rich Wolf-Rayet star and an Oe companion star in a 13-year orbit. Near periastron, the winds of the two stars collide a…
