Enhanced Mass Transfer from Extended Shock-Supported Stellar Chromospheres

Soumyadeep Bhattacharjee, Jim Fuller, Kareem El-Badry

Mass transfer (MT) in binary systems is a crucial and complex process. Even before the donor's photosphere fills its Roche lobe, matter from its outer atmosphere can reach the inne…

Transport of Magnetic Fields by Thermohaline Convection in Crystallizing White Dwarfs

Nicolas Frazao Fernandes, J. R. Fuentes, Jim Fuller

The origins of strong magnetic fields observed in many white dwarfs are uncertain. Recent observations show that such fields are more common for white dwarfs with crystallized core…

Terminal instability of the Solar System triggered by stochastic solar mass loss

Konstantin Batygin, Jim Fuller, Fred C. Adams

From its birth, celestial mechanics has been deeply intertwined with the question of the Solar System's dynamical stability. For the inner planets, this question is now statistical…

Accretion Rates and Thermohaline Convection in Polluted White Dwarfs

J. R. Fuentes, Matias Castro-Tapia, Jim Fuller +1

Polluted white dwarfs provide a unique window into the composition of exoplanetary material, but interpreting their surface abundances requires a quantitative understanding of the…

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-consistent…

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…

The Physics of Mass Transfer in Substellar and Low-Mass Binaries

Samuel Whitebook, Jim Fuller, Kevin Burdge +3

Several dozen binary ultracool and brown dwarf systems have been identified to date. These systems represent valuable probes of star and planet formation at the lowest mass scales.…

Thermally inflated accretors in post-mass transfer binaries: Abell 35 and its class revisited

Soumyadeep Bhattacharjee, Kareem El-Badry, Jim Fuller +2

A small but growing class of binaries containing hot () white dwarfs (WDs) and rapidly rotating, apparently subgiant companions -- including the proto…
