Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Federica Rescigno, Manu Stalport, Ancy Anna John +28
We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
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…
Design and Development of Cassegrain Module for PARAS-2 Spectrograph (CAMPAS)
Kevikumar A. Lad, Neelam J. S. S. V. Prasad, Kapil Bharadwaj +5
We present here the design and development of the CAMPAS, the Cassegrain Module for the PARAS-2 spectrograph. PARAS-2 is a high-resolution fiber-fed echelle spectrograph developed…
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…
Exploring Contact Binaries: Observational Analysis of four W Uma Binaries Using Photometry and Spectroscopy
Alaxender Panchal, Yogesh Chandra Joshi, Vishal Joshi +1
We present the multi-band photometric and low-resolution spectroscopic analysis of four W Ursae Majoris eclipsing binaries (EWs) - J080510.1+141528 (hereinafter as J0805a), J080516…
TOI-6038 A b: A dense sub-Saturn in the transition regime between the Neptunian ridge and savanna
Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13
We present the discovery and characterization of a sub-Saturn exoplanet, TOI-6038~A~b, using the PARAS-2 spectrograph. The planet orbits a bright (), metal-rich late F-typ…
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…
The PRL 2.5m Telescope and its First Light Instruments: FOC & PARAS-2
Abhijit Chakraborty, Kapil Kumar Bharadwaj, Neelam J. S. S. V. Prasad +7
We present here the information on the design and performance of the recently commissioned 2.5-meter telescope at the PRL Mount Abu Observatory, located at Gurushikhar, Mount Abu,…
