Wind-Reprocessed Transients from Stellar-mass Black Hole Tidal Disruption Events
Kyle Kremer, Brenna Mockler, Anthony L. Piro +1
Tidal disruptions of stars by stellar-mass black holes are expected to occur frequently in dense star clusters. Building upon previous studies that performed hydrodynamic simulatio…
Correlating Changes in Spot Filling Factors with Stellar Rotation: The Case of LkCa 4
Facundo Pérez Paolino, Jeffrey S. Bary, Michael S. Petersen +4
We present a multi-epoch spectroscopic study of LkCa 4, a heavily spotted non-accreting T Tauri star. Using SpeX at NASA's Infrared Telescope Facility (IRTF), 12 spectra were colle…
Partial Tidal Disruption of Main-Sequence Stars by Intermediate-Mass Black Holes
Fulya Kıroğlu, James C. Lombardi, Kyle Kremer +3
We study close encounters of a middle-age main-sequence star (modeled using MESA) with massive black holes through hydrodynamic simulations, and explore in particula…
Formation of Low-mass Black Holes and Single Millisecond Pulsars in Globular Clusters
Kyle Kremer, Claire S. Ye, Fulya Kıroğlu +3
Close encounters between neutron stars and main-sequence stars occur in globular clusters and may lead to various outcomes. Here we study encounters resulting in tidal disruption o…
Hydrodynamics of Collisions and Close Encounters between Stellar Black Holes and Main-sequence Stars
Kyle Kremer, James C. Lombardi, Wenbin Lu +2
Recent analyses have shown that close encounters between stars and stellar black holes occur frequently in dense star clusters. Depending upon the distance at closest approach, the…
Simulating a stellar contact binary merger -- I. Stellar models
Roger W. M. Hatfull, Natalia Ivanova, James C. Lombardi
We study the initial conditions of a common envelope (CE) event resulting in a stellar merger. A merger's dynamics could be understood through its light curve, but no synthetic lig…
