Younger age for the oldest magnetic white dwarfs
Sivan Ginzburg
Sufficiently old white dwarfs cool down through a convective envelope that directly couples their degenerate cores to the surface. Magnetic fields may inhibit this convection by st…
Slow convection and fast rotation in crystallization-driven white dwarf dynamos
Sivan Ginzburg, Jim Fuller, Adela Kawka +1
It has been recently suggested that white dwarfs generate magnetic fields in a process analogous to the Earth. The crystallization of the core creates a compositional inversion tha…
Eccentric millisecond pulsars by resonant convection
Sivan Ginzburg, Eugene Chiang
Eccentric millisecond pulsars (eMSPs) with white dwarf companions exhibit orbital eccentricities orders of magnitude larger than predicted by turbulent convection in the white dwar…
Novae heat their food: mass transfer by irradiation
Sivan Ginzburg, Eliot Quataert
A nova eruption irradiates and heats the donor star in a cataclysmic variable to high temperatures , causing its outer layers to expand and overflow the Roche lobe. We…
Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY
J. J. Wang, A. Vigan, S. Lacour +101
We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…
As the Worlds Turn: Constraining Spin Evolution in the Planetary-Mass Regime
Marta L. Bryan, Sivan Ginzburg, Eugene Chiang +4
To understand how planetary spin evolves and traces planet formation processes, we measure rotational line broadening in eight planetary-mass objects (PMOs) of various ages (1--800…
