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…
Optical spectroscopy and photometry of main-belt asteroids with a high orbital inclination
Aya Iwai, Yoichi Itoh, Tsuyoshi Terai +3
We carried out low-resolution optical spectroscopy of 51 main-belt asteroids, most of which have highly-inclined orbits. They are selected from D-type candidates in the SDSS-MOC 4…
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…
Modelling the mid-infrared polarization in dust around young stars
Gautam Saikia, Rupjyoti Gogoi, Ranjan Gupta +1
The presence of crystalline silicates has been detected in the circumstellar environment of several young stars in the recent past and there is evidence of silicon carbide (SiC) de…
