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…
ROCKETS I: Investigating the Impact of the Rocket Effect on Two Nearby Young Open Clusters Encased in Infrared Bubbles
R. Arun, G. Maheswar, Annapurni Subramaniam +5
We introduce ROCKETS (Rocket-driven Cluster Kinematics & Triggered Star-formation), a Gaia based programme investigating kinematic fingerprints of stellar feedback or rocket effect…
Discovery of Fullerenes in the Shell of Candidate Luminous Blue Variable WRAY 16-232
R. Arun, S. A. Prasoon, Blesson Mathew +5
We report the discovery of fullerene in the circumstellar environment of WRAY~16-232, a strong candidate luminous blue variable. Multiple pointings of archival \textit{Spitzer} IRS…
Analysis of Forbidden Neon Emission lines in HAeBe Stars using Spitzer IRS spectra
D. Akhila, Blesson Mathew, S. Nidhi +7
We analyzed high-resolution mid-infrared spectra of 78 well-known Herbig Ae/Be (HAeBe) stars using Spitzer InfraRed Spectrograph data, focusing on the detection of [Ne {\sc II}] an…
