A Novel Approach to Identify Unseen Companions: An In-Depth study of GDR3 220_28
T. B. Cysil, Blesson Mathew, B. Shridharan +6
Emission lines in the spectrum and the excess seen in the spectral energy distribution (SED) at infrared (IR) wavelengths serve as crucial indicators of accretion activity and the…
A comprehensive multi-wavelength study of two X-ray emitting Be stars
Hema Anilkumar, Blesson Mathew, Savithri H. Ezhikode +4
We present a multi-wavelength study of two X-ray-emitting Be stars, CXOU J052218.4+332820 (Star 1) and CXOU J052304.2+332846 (Star 2), identified from the LAMOST DR5 Hot emission-l…
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…
Investigating the properties of nearby young moving groups using GaiaDR3
Mamta Lad, Ujjwal Krishnan, Blesson Mathew +4
Moving groups, which are gravitationally unbound collections of stars spread over large portions of the sky, pose challenges to their identification. Analyzing the three-dimensiona…
A multi-epoch spectral and photometric study to understand the nature of the interesting Be star candidate HD 249179
Suman Bhattacharyya, Blesson Mathew, S Muneer +2
HD 249179, a B5 star with unclear classification as either a classical Be star or a high-mass X-ray binary (HMXB) system, is investigated using the first multi-epoch spectral and p…
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…
Non-Linear Solar EUV-Driven Sodium Release from the Lunar Surface: A Contrast to the Linear PSD Model
A Devaraj, S Narendranath, Sreeja S Kartha +7
The correlation between solar Extreme Ultra-Violet (EUV) radiation above 8.8 eV and the release of sodium from the lunar surface via photon-stimulated desorption (PSD) is investiga…
Probing the resolved K-S relation in nearby galaxies: Insights from UVIT and ALMA observations
K Sruthi, Sreeja S Kartha, Blesson Mathew +3
This study examines the resolved Kennicutt Schmidt (rKS) relation, defined as the connection between the star formation rate surface density (Sigma SFR) and the molecular gas mass…
Polycyclic Aromatic Hydrocarbons in the circumstellar medium of Herbig Ae/Be stars
R. Arun, Blesson Mathew, B. Shridharan +4
We present a comprehensive mid-infrared spectroscopic survey of 124 Herbig Ae/Be stars using newly processed Spitzer/IRS spectra from the newly released CASSISjuice database. Based…
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…
Spectroscopic study of late-type emission-line stars using the data from LAMOST DR6
D. Edwin, Blesson Mathew, B. Shridharan +5
Low-mass emission-line stars belong to various evolutionary stages, from pre-main-sequence young stars to evolved stars. In this work, we present a catalog of late-type (F0 to M9)…
Serendipitous detection of an intense X-ray flare in the weak-line T Tauri star KM Ori with SRG/eROSITA
Savithri H. Ezhikode, Hema Anilkumar, R. Arun +8
Weak-line T Tauri stars (WTTS) exhibit X-ray flares, likely resulting from magnetic reconnection that heats the stellar plasma to very high temperatures. These flares are difficult…
Insights on the Optical and Infrared Nature of MAXI J0709-159: Implications for High-Mass X-ray Binaries
Suman Bhattacharyya, Blesson Mathew, Gourav Banerjee +4
In our previous study (Bhattacharyya et al., 2022), HD~54786, the optical counterpart of the MAXI J0709-159 system, was identified to be an evolved star, departing from the main se…
