Masses and radii of four very low mass stars in F+M eclipsing binary systems
Priyanka Chaturvedi, Rishikesh Sharma, Abhijit Chakraborty +2
Eclipsing Binaries (EBs) with one of the companions as very low mass stars (VLMS or M dwarfs) are testbeds to substantiate stellar models and evolutionary theories. Here, we presen…
Evidence of a Sub-Saturn around EPIC~211945201
Abhijit Chakraborty, Arpita Roy, Rishikesh Sharma +4
We report here strong evidence for a sub-Saturn around EPIC~211945201 and confirm its planetary nature. EPIC~211945201b was found to be a planetary candidate from {\it K2} photomet…
An Infrared Photometric and Spectroscopic Study of Post-AGB Stars
V. Venkata Raman, B. G. Anandarao, P. Janardhan +1
We present here mid-infrared (IR) spectra and modeling of the spectral energy distribution (SED) of a selection of post-Asymptotic Giant Branch (PAGB) stars. The mid-IR s…
Spectral Analysis Code: PARAS SPEC
Priyanka Chaturvedi, Abhijit Chakraborty, B. G. Anandarao
The light emitted from the stellar photosphere serves as a unique signature for the nature of stars. The behaviour of these stellar lines depend upon the surface temperature, mass,…
Precision velocimetry planet hunting with PARAS: Current performance and lessons to inform future extreme precision radial velocity instruments
Arpita Roy, Abhijit Chakraborty, Suvrath Mahadevan +5
PARAS is a fiber-fed stabilized high-resolution cross-dispersed echelle spectrograph, located on the 1.2 m telescope in Mt. Abu India. Designed for exoplanet detection, PARAS is ca…
Detection of a very low mass star in an Eclipsing Binary system
Priyanka Chaturvedi, Abhijit Chakraborty, B. G. Anandarao +2
We report the detection of a very low mass star (VLMS) companion to the primary star 1SWASPJ234318.41+295556.5A (J2343+29A), using radial velocity (RV) measurements from the PARAS…
