High-resolution spectroscopy of the variable hot post-AGB star LS 4331 (IRAS 17381-1616)
N. P. Ikonnikova, M. Parthasarathy, I. A. Shaposhnikov +2
An analysis of high-resolution () optical spectrum of hot (B1Ibe) post-AGB star LS 4331 (IRAS 17381-1616) is presented. The detailed identification of the observed ab…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the Case of WR 127 (Hen 3-1772)
I. A. Shaposhnikov, A. M. Cherepashchuk, A. V. Dodin +1
We aim at searching for secular evolution of the orbital period in the short-period binary system WR 127 (WN3b+O9.5V, ). We performed new low-resolution spectroscopic…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the case of V444 Cyg
I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1
We present the results of new photometric and spectroscopic observations of WN5+O6 binary V444 Cyg and a detailed analysis of extant spectroscopy and photometry. Using elements of…
