Hydrogen airglow from an escaping ultrahot Jupiter atmosphere
Yapeng Zhang, Chenliang Huang, Aaron Householder +17
Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…
Helium escape in context: Comparative signatures of four close-in exoplanets
Anna Ruth Taylor, Tommi T. Koskinen, Chenliang Huang +2
Observations of escaping atmospheres on close-in exoplanets show a wide range in the strength and morphology of He I 10830 A and H I absorption. Scaling relations attempt to link t…
Magrathea v2: A planetary interior modeling platform in C++
David R. Rice, Chenliang Huang, Robert Royer +5
Magrathea is an open-source C++ code for modeling the internal structure of differentiated planets. The initial release, Huang et al. (2022), introduced the base solver, a modular…
Uncertainties in the Inference of Internal Structure: The Case of TRAPPIST-1 f
David R. Rice, Chenliang Huang, Jason H. Steffen +1
We use the TRAPPIST-1 system as a model observation of Earth-like planets. The densities of these planets being 1-10% less than the Earth suggest that the outer planets may host si…
PEPSI's non-detection of escaping hydrogen and metal lines adds to the enigma of WASP-12 b
Anusha Pai Asnodkar, Ji Wang, Madelyn Broome +5
WASP-12 b is an ultra-hot Jupiter (UHJ) of special interest for atmospheric studies since it is on an inspiraling orbit in an extreme environment of intense radiation and circumste…
CUTE reveals escaping metals in the upper atmosphere of the ultra-hot Jupiter WASP-189b
A. G. Sreejith, Kevin France, Luca Fossati +12
Ultraviolet observations of Ultra-hot Jupiters (UHJs), exoplanets with temperatures over 2000\,K, provide us with an opportunity to investigate if and how atmospheric escape shapes…
A hydrodynamic study of the escape of metal species and excited hydrogen from the atmosphere of the hot Jupiter WASP-121b
Chenliang Huang, Tommi Koskinen, Panayotis Lavvas +1
In the near-UV and optical transmission spectrum of the hot Jupiter WASP-121b, recent observations have detected strong absorption features of Mg, Fe, Ca, and H, extending outsi…
Mass loss by atmospheric escape from extremely close-in planets
Tommi Koskinen, Panayotis Lavvas, Chenliang Huang +3
We explore atmospheric escape from close-in exoplanets with the highest mass loss rates. First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe…
MAGRATHEA: an open-source spherical symmetric planet interior structure code
Chenliang Huang, David R. Rice, Jason H. Steffen
MAGRATHEA is an open-source planet structure code that considers the case of fully differentiated spherically symmetric interiors. Given the mass of each layer and the surface temp…
H-Alpha Variability of V1298 Tau c
Everett Schlawin, Ilya Ilyin, Adina D. Feinstein +5
The 23 Myr system V1298 Tau hosts four transiting planets and is a valuable laboratory for exploring the early stages of planet evolution soon after formation of the star. We obser…
Atmosphere escape inferred from modelling the H transmission spectrum of WASP-121b
Dongdong Yan, Jianheng Guo, Chenliang Huang +1
The escaping atmospheres of hydrogen driven by stellar X-ray and extreme Ultraviolet (XUV) have been detected around some exoplanets by the excess absorption of Ly in far ultrav…
Sodium and Potassium Signatures of Volcanic Satellites Orbiting Close-in Gas Giant Exoplanets
Apurva V. Oza, Robert E. Johnson, Emmanuel Lellouch +12
Extrasolar satellites are generally too small to be detected by nominal searches. By analogy to the most active body in the Solar System, Io, we describe how sodium (Na I) and pota…
Bond strengthening in dense H2O and implications to planetary composition
Zachary M. Grande, Chenliang Huang, Dean Smith +5
H2O is an important constituent in planetary bodies, controlling habitability and, in geologically-active bodies, plate tectonics. At pressures within the interior of many planets,…
Electron scattering wings on lines in interacting supernovae
Chenliang Huang, Roger Chevalier
We consider the effect of electron scattering on lines emitted as a result of supernova interaction with a circumstellar medium, assuming that the scattering occurs in ionized gas…
A Model of the H and Na Transmission Spectrum of HD 189733b
Chenliang Huang, Phil Arras, Duncan Christie +1
This paper presents a detailed hydrostatic model of the upper atmosphere of HD 189733b, with the goal of constraining its temperature, particle densities, and radiation field over…
Near infrared spectroscopy of the type IIn SN 2010jl: evidence for high velocity ejecta
H. Jacob Borish, Chenliang Huang, Roger A. Chevalier +3
The Type IIn supernova SN 2010jl was relatively nearby and luminous, allowing detailed studies of the near-infrared (NIR) emission. We present 1 - 2.4 micron spectroscopy over the…
