Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
Searching for young runaways across the sky
Marina Kounkel, Aidan McBride, Keivan G. Stassun +1
We present a catalog of 3354 candidate young stars within 500 pc that appear to have been ejected from their parent associations with relative speeds of >5 km/s. These candidates h…
Searching for the extra-tidal stars of globular clusters using high-dimensional analysis and a core particle spray code
Steffani M. Grondin, Jeremy J. Webb, Nathan W. C. Leigh +2
Three-body interactions can eject stars from the core of a globular cluster, causing them to enter the Galactic halo as extra-tidal stars. While finding extra-tidal stars is impera…
Aligning Retrograde Nuclear Cluster Orbits with an Active Galactic Nucleus Accretion Disc
Syeda S. Nasim, Gaia Fabj, Freddy Caban +6
Stars and stellar remnants orbiting a supermassive black hole (SMBH) can interact with an active galactic nucleus (AGN) disc. Over time, prograde orbiters (inclination $i<90^{\circ…
The thermodynamics of stellar multiplicity: dynamical evolution of binary star populations in dense stellar environments
N. W. C. Leigh, N. C. Stone, J. J. Webb +1
We recently derived, using the density-of-states approximation, analytic distribution functions for the outcomes of direct single-binary scatterings (Stone & Leigh 2019). Using the…
Globular Clusters UVIT Legacy Survey (GlobULeS) I. FUV-optical Color-Magnitude Diagrams for Eight Globular Clusters
Snehalata Sahu, Annapurni Subramaniam, Gaurav Singh +22
We present the first results of eight Globular Clusters (GCs) from the AstroSat/UVIT Legacy Survey program GlobULeS based on the observations carried out in two FUV filters (F148W…
Stellar Triples as a Source for Ba Stars
Yan Gao, Silvia Toonen, Nathan Leigh
Barium stars have been studied extensively over the past few decades, yet our current understanding of how these intriguing objects formed leaves much to be desired. Many trends ob…
Tidal Disruption Events by Compact Supermassive Black Hole Binaries
Taeho Ryu, Alessandro A. Trani, Nathan W. C. Leigh
Stars can be tidally destroyed or swallowed by supermassive black hole binaries. Using a large number of accurate few-body simulations, we investigate the enhancement and suppressi…
