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…
Forging neon-distilling white dwarfs in the stellar engulfments of helium white dwarfs
Nicholas Z. Rui, Jim Fuller
Once carbon--oxygen white dwarfs cool sufficiently, they crystallize from the inside out. If the white dwarf is rich enough in , these crystallized solids are b…
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…
A half-ring of ionized circumstellar material trapped in the magnetosphere of a white dwarf merger remnant
Andrei A. Cristea, Ilaria Caiazzo, Tim Cunningham +31
Many white dwarfs are observed in compact double white dwarf binaries and, through the emission of gravitational waves, a large fraction are destined to merge. The merger remnants…
Seismology and diffusion of ultramassive white dwarf magnetic fields
Daniel Blatman, Nicholas Z. Rui, Sivan Ginzburg +1
Ultramassive white dwarfs (UMWDs; defined by masses ) are prime targets for seismology, because they pass through the ZZ Ceti instability strip at the s…
It's not just a phase: oblique pulsations in magnetic red giants and other stochastic oscillators
Nicholas Z. Rui, Jim Fuller, J. M. Joel Ong
Magnetic fields play a significant role in stellar evolution. In the last few years, asteroseismology has enabled the measurement of strong magnetic fields --$10^6\,\mathrm{G…
Magnetic dynamos powered by white dwarf superficial convection
Rom Yaakovyan, Sivan Ginzburg, Jim Fuller +1
When the effective temperature of a cooling white dwarf drops below the ionization limit, it develops a surface convection zone that may generate a magnetic field …
Supersensitive seismic magnetometry of white dwarfs
Nicholas Z. Rui, Jim Fuller, J. J. Hermes
The origin of magnetic fields in white dwarfs (WDs) remains mysterious. Magnetic WDs are traditionally associated with field strengths , set by the sensitivi…
