Hot Jupiter engulfment by a red giant in 3D hydrodynamics
Mike Y. M. Lau, Matteo Cantiello, Adam S. Jermyn +3
Hot Jupiters are gas giant planets with orbital periods of a few days and are found in 0.1-1% of Sun-like stars. They are expected to be engulfed during their host star's radial ex…
Constraining planetary mass-loss rates by simulating Parker wind profiles with Cloudy
Dion Linssen, Antonija Oklopčić, Morgan MacLeod
Models of exoplanet atmospheres based on Parker-wind density and velocity profiles are a common choice in fitting spectroscopic observations tracing planetary atmospheric escape. I…
Keck/NIRSPEC studies of He I in the atmospheres of two inflated hot gas giants orbiting K dwarfs: WASP-52b and WASP-177b
James Kirk, Leonardo A. Dos Santos, Mercedes López-Morales +5
We present the detection of neutral helium at 10833A in the atmosphere of WASP-52b and tentative evidence of helium in the atmosphere of the grazing WASP-177b, using high-resolutio…
Dusty, Self-obscured Transients from Stellar Coalescence
Morgan MacLeod, Kishalay De, Abraham Loeb
We discuss the central role that dust condensation plays in shaping the observational appearance of outflows from coalescing binary systems. As binaries begin to coalesce, they sho…
Formation of black holes in the pair-instability mass gap: Hydrodynamical simulations of a head-on massive star collision
Alessandro Ballone, Guglielmo Costa, Michela Mapelli +3
The detection of the binary black hole merger GW190521, with primary black hole mass , proved the existence of black holes in the theoretically pr…
Hydrodynamics and survivability during post-main-sequence planetary engulfment
Ricardo Yarza, Naela Razo Lopez, Ariadna Murguia-Berthier +6
The engulfment of substellar bodies (SBs, such as brown dwarfs and planets) by giant stars is a possible explanation for rapidly rotating giants, lithium-rich giants, and the prese…
