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…
Star Clusters in the Ultraviolet
Annapurni Subramaniam, Samyaday Choudhury, Richard de Grijs +5
Ultraviolet (UV) observations provide a powerful window into the hot and evolved stellar populations that shape the structure, evolution and integrated light of star clusters. Beca…
Nine years of UVIT: assessing sensitivity variation
Akanksha Dagore, Prajwel Joseph, S. N. Tandon +3
The Ultra-Violet Imaging Telescope (UVIT) is one of the five payloads onboard the first Indian multiwavelength astronomical observatory, AstroSat, launched by the Indian Space Rese…
Tidal Tails and Their Dynamics in Open Clusters Using Gaia DR3
Ira Sharma, Vikrant V. Jadhav, Annapurni Subramaniam
This research presents unsupervised machine learning and statistical techniques to detect and analyze tidal tails in five open clusters, BH 164, Alessi 2, NGC 2281, NGC 2354, and M…
Detection of young massive white dwarfs in core-collapsed globular cluster NGC 362
R. K. S. Yadav, Arvind K. Dattatrey, Annapurni Subramaniam +2
Core-collapsed globular clusters are ideal targets to explore the presence of stellar collision products. Here, we have studied seventeen FUV bright white dwarf members in the glob…
Tidal tails in open clusters: Morphology, binary fraction, dynamics, and rotation
Ira Sharma, Vikrant V. Jadhav, Annapurni Subramaniam +1
Context: This research presents unsupervised machine learning and statistical methods to identify and analyze tidal tails in open star clusters using data from the Gaia DR3 catalog…
Orbits and vertical height distribution of 4006 open clusters in the Galactic disk using Gaia DR3
Geeta Rangwal, Aman Arya, Annapurni Subramaniam +2
Open clusters (OCs) in the Galaxy are excellent probes for tracing the structure and evolution of the Galactic disk. We present an updated catalog of parameters for 1,145 OCs, esti…
A Partial Near-infrared Guide Star Catalog for Thirty Meter Telescope Operations
Sarang Shah, Smitha Subramanian, Avinash C. K. +10
At first light, the Thirty Meter Telescope (TMT) near-infrared (NIR) instruments will be fed by a multiconjugate adaptive optics instrument known as the Narrow Field Infrared Adapt…
Discovery of a barium blue straggler star in M67 and sighting of its WD companion*
Harshit Pal, Annapurni Subramaniam, Arumalla B. S. Reddy +1
We report the discovery of a barium blue straggler star (BSS) in M67, exhibiting enhancements in slow neutron-capture (-) process elements. Spectroscopic analysis of two BSSs (W…
Regional and Global Collaborations in Astronomy
Kazuhiro Sekiguchi, Jess McIver, Annapurni Subramaniam +10
Policy Brief on "Regional and Global Collaborations in Astronomy", distilled from the corresponding panel that was part of the discussions during S20 Policy Webinar on Astroinforma…
AstroInformatics: Recommendations for Global Cooperation
Ashish Mahabal, Pranav Sharma, Rana Adhikari +45
Policy Brief on "AstroInformatics, Recommendations for Global Collaboration", distilled from panel discussions during S20 Policy Webinar on Astroinformatics for Sustainable Develop…
