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…
Black widow formation by pulsar irradiation and sustained magnetic braking
Sivan Ginzburg, Eliot Quataert
Black widows are millisecond pulsars with low-mass companions, a few per cent the mass of the sun, on orbits of several hours. These companions are presumably the remnants of main…
Heavy-metal Jupiters by major mergers: metallicity vs. mass for giant planets
Sivan Ginzburg, Eugene Chiang
Some Jupiter-mass exoplanets contain of metals, well above the typically needed in a solid core to trigger giant planet formation by ru…
Keck/NIRC2 '-Band Imaging of Jovian-Mass Accreting Protoplanets around PDS 70
Jason J. Wang, Sivan Ginzburg, Bin Ren +42
We present '-band imaging of the PDS 70 planetary system with Keck/NIRC2 using the new infrared pyramid wavefront sensor. We detected both PDS 70 b and c in our images, as well…
How Consumption and Repulsion Set Planetary Gap Depths and the Final Masses of Gas Giants
Mickey Rosenthal, Eugene Chiang, Sivan Ginzburg +1
Planets open gaps in discs. Gap opening is typically modeled by considering the planetary Lindblad torque which repels disc gas away from the planet's orbit. But gaps also clear be…
Re-inflation of warm and hot Jupiters
Thaddeus D. Komacek, Daniel P. Thorngren, Eric D. Lopez +1
Understanding the anomalous radii of many transiting hot gas giant planets is a fundamental problem of planetary science. Recent detections of re-inflated warm Jupiters orbiting po…
Black widow evolution: magnetic braking by an ablated wind
Sivan Ginzburg, Eliot Quataert
Black widows are close binary systems in which a millisecond pulsar is orbited by a companion a few per cent the mass of the sun. It has been suggested that the pulsar's rotational…
