Runaway Coalescence of Pre-Common-Envelope Stellar Binaries
Morgan MacLeod, Abraham Loeb
We study the process of runaway, unstable Roche lobe overflow in coalescing binary systems and its dependence on the properties of the binary involved. We create three-dimensional…
Common Envelope Wind Tunnel: The Effects of Binary Mass Ratio and Implications for the Accretion-Driven Growth of LIGO Binary Black Holes
Soumi De, Morgan MacLeod, Rosa Wallace Everson +3
We present three-dimensional local hydrodynamic simulations of flows around objects embedded within stellar envelopes using a "wind tunnel" formalism. Our simulations model the com…
The Effect of Star--Disk Interactions on Highly Eccentric Stellar Orbits in Active Galactic Nuclei: A Disk Loss Cone and Implications for Stellar Tidal Disruption Events
Morgan MacLeod, Douglas N. C. Lin
Galactic center black holes appear to be nearly universally surrounded by dense stellar clusters. When these black holes go through an active accretion phase, the multiple componen…
Self-lensing Discovery of a White Dwarf in an Unusually Wide Orbit Around a Sun-like Star
Kento Masuda, Hajime Kawahara, David W. Latham +4
We report the discovery of the fifth self-lensing binary in which a low-mass white dwarf (WD) gravitationally magnifies its 15th magnitude G-star companion, KIC 8145411, during ecl…
Explosions Driven by the Coalescence of a Compact Object with the Core of a Massive-Star Companion Inside a Common Envelope: Circumstellar Properties, Light Curves, and Population Statistics
Sophie Lund Schrøder, Morgan MacLeod, Abraham Loeb +2
We model explosions driven by the coalescence of a black hole or neutron star with the core of its massive-star companion. Upon entering a common envelope phase, a compact object m…
Correlation Between Mass Segregation and Structural Concentration in Relaxed Stellar Clusters
Ruggero de Vita, Michele Trenti, Morgan MacLeod
The level of mass segregation in the core of globular clusters has been previously proposed as a potential indicator of the dynamical constituents of the system, such as presence o…
