TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star
Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42
We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…
Direct Optical Evidence of Late-Stage Infall in AB Aurigae: A Stagnant [O I] Reservoir and a Crushed Magnetosphere
Dipen Sahu, Rishikesh Sharma, Shubhendra Nath Das +2
Massive planet-carved cavities in transition disks should theoretically throttle inward gas transport, challenging our understanding of how central stars maintain vigorous accretio…
Design and development of Fabry-Perot based wavelength calibration system for PARAS-2 spectrograph
Shubhendra Nath Das, Kapil Kumar Bharadwaj, Abhijit Chakraborty +5
Precise wavelength calibration is essential for high-precision radial velocity (RV) spectrographs, necessitating a stable calibrator that provides a dense grid of uniformly spaced…
TOI-7154b: A Close-in Massive Brown Dwarf in an Eccentric Orbit
Rohan Ch. Das, Churchil Dwivedi, Rishikesh Sharma +12
We report here the discovery and characterization of a high-mass transiting brown dwarf in a close-in orbit around its host star, TOI-7154. Initially, the host star was identified…
Discovery and characterization of a dense sub-Saturn TOI-6651b
Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13
We report the discovery and characterization of a transiting sub-Saturn exoplanet TOI-6651b using PARAS-2 spectroscopic observations. The host, TOI-6651 (), is a…
