Host-star metallicities and kinematics of directly imaged brown-dwarf companions
C. Swastik, R. K. Banyal, M. Muduli +15
Brown dwarfs are common as free-floating objects but rare as close companions to Sun-like stars, a disparity known as the "brown-dwarf desert". Host-star metallicity can constrain…
uGMRT Survey of EXoplanets Around M-dwarfs (GS-EXAM): Radio observations of GJ 1151
Mayank Narang, Manoj Puravankara, H. K. Vedantham +9
Coherent radio emission with properties similar to planetary auroral signals has been reported from GJ 1151, a quiescent, slow-rotating mid-M star, by the LOFAR Two-metre (120-170…
Demography of stellar radio population within 500 pc: A VLASS-Gaia DR3 study
Ayanabha De, Mayank Narang, Manoj Puravankara +5
In this work, we have carried out a systematic analysis of the VLASS quick look catalogs together with \textit{Gaia DR3} to identify the optical counterparts of 3~GHz radio emitter…
Host star properties of hot, warm and cold Jupiters in the solar neighborhood from \textit{Gaia} DR3: clues to formation pathways
Bihan Banerjee, Mayank Narang, P. Manoj +5
Giant planets exhibit diverse orbital properties, hinting at their distinct formation and dynamic histories. In this paper, using DR3, we investigate if and how the…
A uGMRT search for radio emission from planets around evolved stars
Mayank Narang, P. Manoj, Ishwara Chandra +8
In this work, we present the results from a study using the Giant Meterwave Radio Telescope (GMRT) to search for radio {emission} from planets around three evolved stars namely …
Identifying the population of T-Tauri stars in Taurus: UV-optical synergy
Prasanta K. Nayak, Mayank Narang, Manoj Puravankara +9
With the third data release of the Gaia mission DR3 with its precise photometry and astrometry, it is now possible to study the behaviour of stars at a scale never seen befo…
A compact cryogenic configurable slit unit for a multi-object infrared spectrograph:Design and Development of a prototype at TIFR
P. P. Madhwani, A. P. K. Kutty, B. Mookerjea +5
We present a cryogenic configurable slit unit (CSU) for a multi object infrared spectrograph with an effective field of view of 9.1 arcmin x 9.1 arcmin that was completely conceive…
Optical spectroscopy of Gaia detected protostars with DOT: can we probe protostellar photospheres?
Mayank Narang, Manoj Puravankara, Himanshu Tyagi +7
Optical spectroscopy offers the most direct view of the stellar properties and the accretion indicators. Standard accretion tracers, such as , , and, Ca II triplet lines, a…
uGMRT observations of the hot-Saturn WASP 69b: Radio-Loud Exoplanet-Exomoon Survey II (RLEES II)
Mayank Narang, Apurva V. Oza, Kaustubh Hakim +7
Exomoons have so far eluded ongoing searches. Several studies have exploited transit and transit timing variations and high-resolution spectroscopy to identify potential exomoon ca…
Carbon abundance of stars in the LAMOST-Kepler field
Athira Unni, Mayank Narang, Thirupathi Sivarani +5
The correlation between host star iron abundance and the exoplanet occurrence rate is well-established and arrived at in several studies. Similar correlations may be present for th…
