Collisional Shaping of Nuclear Star Cluster Density Profiles
Sanaea C. Rose, Morgan MacLeod
A supermassive black hole (SMBH) surrounded by a dense, nuclear star cluster resides at the center of many galaxies. In this dense environment, high-velocity collisions frequently…
Interstellar Meteors from Tidal Disruption of Rocky Planets on Eccentric Orbits Around M Dwarfs
Abraham Loeb, Morgan MacLeod
Low-mass stars appear to frequently host planetary systems. When these rocky planets develop high eccentricities as a result of secular torques or dynamical scatterings, they occas…
The Impact of Angular Momentum Loss on the Outcomes of Binary Mass Transfer
Reinhold Willcox, Morgan MacLeod, Ilya Mandel +1
We use the rapid binary population synthesis code COMPAS to investigate commonly used prescriptions for the determination of mass transfer stability in close binaries and the orbit…
A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation
Michael Gully-Santiago, Caroline V. Morley, Jessica Luna +14
Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present t…
Giant Tidal Tails of Helium Escaping the Hot Jupiter HAT-P-32 b
Zhoujian Zhang, Caroline V. Morley, Michael Gully-Santiago +14
Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. Such analysis has been enabled by observations of the helium…
Left Ringing: Betelgeuse Illuminates the Connection Between Convective outbursts, Mode switching, and Mass Ejection in Red Supergiants
Morgan MacLeod, Andrea Antoni, Caroline D. Huang +2
Betelgeuse, the nearest red supergiant, dimmed to an unprecedented level in early 2020. The star emerged from this Great Dimming episode with its typical, roughly 400-day pulsation…
