White Dwarf Kicks via Episodic Mass Ejection from Red Giant Stars
Jim Fuller
Recent observations have found evidence that white dwarf (WD) stars receive a kick of 1 km/s as the envelopes of their red giant progenitors are expelled. We show that these…
Modern tidal interaction models for rapid binary population synthesis: II. Binary black hole formation, mergers, and spins
Veome Kapil, Ilya Mandel, Jeff Riley +3
We present predictions for the merger rates and effective spin () distribution of binary black holes (BBHs) from isolated binary evolution, using a new self-consisten…
Transonic Solutions for Recombination-Driven Stellar Winds
Ilan Strusberg, Re'em Sari, Jim Fuller
We present an analytical stationary isentropic solution of the spherically symmetric Euler equations in the gravitational field of a star using an equation of state of ionizable mo…
Wildly Oscillating Stars -- Unexplained dense ridge-like frequency agglomerations in A and F type pulsators
V. Antoci, J. Labadie-Bartz, M. Swiech +14
We investigate the origin of the dense, ridge-like frequency clusters observed in a subset of A and F type pulsating stars, which we refer to as `wildly oscillating' stars (WOS). T…
Deep Adaptive Optics Imaging Rules Out a Helium Star Companion to PSR J1928+1815
Pranav Nagarajan, Kareem El-Badry, Jim Fuller +2
PSR J1928+1815 is a 10.55 ms millisecond pulsar in a 3.6 hr orbit with a massive (-) companion that produces extended radio eclipses. The companion, proposed t…
Radiatively Cooled Binary Mass Transfer: Flow Structure, Luminosities, and L2 Outflows Across Mass Transfer Rates
Peter Scherbak, Wenbin Lu, Jim Fuller
High rates of stable mass transfer (MT) occur for some binary star systems, resulting in luminous transients and circumbinary outflows (CBOs). We perform hydrodynamical simulations…
