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…
Common Envelope Mass Ejection in Evolved Stars: Modeling the Dust Emission from post-RGB stars in the LMC
Geetanjali Sarkar, Raghvendra Sahai
Common Envelope (CE) systems are the result of Roche lobe overflow in interacting binaries. The subsequent evolution of the CE, its ejection and the formation of dust in its ejecta…
Analysis of absorption lines in the high resolution spectra of five hot post-AGB candidates
A. Herrero, M. Parthasarathy, S. Simon-Diaz +3
From an analysis of absorption lines in the high resolution spectra we have derived the radial velocities, stellar parameters (Teff, gravity, wind-strength parameter logQ and proje…
High-resolution spectroscopy of the high velocity hot post-AGB star IRAS 18379-1707 (LS 5112)
N. P. Ikonnikova, M. Parthasarathy, A. V. Dodin +2
The high-resolution () optical spectrum of the B-type supergiant LS 5112, identified as the optical counterpart of the post-AGB candidate IRAS 18379-1707, is analysed…
Line identification and photometric history of the hot post-AGB star Hen 3-1013 (IRAS 14331-6435)
V. P. Arkhipova, M. Parthasarathy, N. P. Ikonnikova +4
We present a study of the high-resolution optical spectrum for the hot post-asymptotic giant branch (post-AGB) star, Hen 3-1013, identified as the optical counterpart of the infrar…
High resolution spectroscopy of the high velocity hot post-AGB star LS III +52 24 (IRAS 22023+5249)
G. Sarkar, D. A. Garcia-Hernandez, M. Parthasarathy +3
The first high-resolution (R~50,000) optical spectrum of the B-type star, LS III +52 24, identified as the optical counterpart of the hot post-AGB candidate IRAS 22023+5249 (I22023…
