Stellar Spectral Interpolation using Machine Learning
Kaushal Sharma, Harinder P. Singh, Ranjan Gupta +6
Theoretical stellar spectra rely on model stellar atmospheres computed based on our understanding of the physical laws at play in the stellar interiors. These models, coupled with…
Spectroscopic Survey of Hα Emission Line Stars Associated with Bright Rimmed Clouds
Kensuke Hosoya, Yoichi Itoh, Yumiko Oasa +2
The results of a spectroscopic survey of H alpha emission line stars associated with fourteen bright rimmed clouds are presented. Slit-less optical spectroscopy was carried out wit…
Spectroscopic and geometrical evolution of the ejecta of the classical nova ASASSN-18fv
M. Pavana, A. Raj, T. Bohlsen +3
The optical spectroscopic observations of ASASSN-18fv observed from 2018 March 24 to 2019 Jan 26 are presented. The optical spectra are obtained from Mirranook, Vainu Bappu and Sou…
Unveiling Vela -- Variability of Interstellar Lines in the Direction of the Vela Supernova Remnant III. Na D and Ca II K
N. Kameswara Rao, David L. Lambert, Arumalla B. S Reddy +4
High-resolution optical spectra were obtained in 2017-2019 with The Southern African Large Telescope of fifteen stars in the direction of the Vela supernova remnant. Interstellar C…
Unveiling Vela - Time Variability of Interstellar Lines in the Direction of the Vela Supernova Remnant II. Na D and Ca II
N. Kameswara Rao, David L. Lambert, Arumalla B. S. Reddy +3
In a survey conducted between 2011-12 of interstellar Na I D line profiles in the direction of the Vela supernova remnant, a few lines of sight showed dramatic changes in low veloc…
The effect of porosity of dust particles on polarization and color with special reference to comets
A. K. Sen, R Botet, R. Vilaplana +2
Cosmic dusts are mostly responsible for polarization of the light that we ob- serve from astrophysical objects. They also lead to color-extinction, thermal re- emission and other s…
