The 3D Cosmic Shoreline for Nurturing Planetary Atmospheres
Zach K. Berta-Thompson, Patcharapol Wachiraphan, Catriona Murray
Various ``cosmic shorelines" have been proposed to delineate which planets have atmospheres. The fates of individual planet atmospheres may be set by a complex sea of growth and lo…
Thermal Eclipse Observation of the Young Hot Neptune AU Mic b with Spitzer
Kevin I. Collins, Peter Plavchan, Zachory Berta-Thompson +11
We present the observation of a secondary eclipse of the young hot Neptune, AU Mic b, in the infrared using the Spitzer Space Telescope. Using a primary transit from Spitzer to con…
The MUSCLES Extension for Atmospheric Transmission Spectroscopy: Spectral energy distributions for 20 exoplanet host stars that JWST observed in Cycle 1
David J. Wilson, Allison Youngblood, Girish M. Duvvuri +11
Correctly interpreting JWST spectra of close-in exoplanets requires a measurement of the X-ray and ultraviolet light that the planets receive from their host stars. Here we provide…
FUMES IV: Optical and Far-ultraviolet Spectra of a Flare on the M Dwarf GJ 4334
Girish M. Duvvuri, J. Sebastian Pineda, Aylin GarcÃa Soto +5
On 2017-09-20 we observed GJ 4334, an M5V dwarf rotating with a period of 23.5 days, simultaneously with both the Space Telescope Imaging Spectrograph aboard Hubble (1160 -- 1710 A…
exoatlas: friendly Python code for exoplanet populations
Zach K. Berta-Thompson, Patcharapol Wachiraphan, Autumn Stephens +6
Planets are complicated. Understanding how they work requires connecting individual objects to the context of broader populations. Exoplanets are easier to picture next to their cl…
The James Webb Space Telescope NIRSpec-PRISM Transmission Spectrum of the Super-Puff, Kepler-51d
Jessica E. Libby-Roberts, Aaron Bello-Arufe, Zachory K. Berta-Thompson +14
Kepler-51 is a 500 Myr G dwarf hosting three "super-puffs" and one low-mass non-transiting planet. Kepler-51d, the coolest (T_eq ~ 350 K) transiting planet in this system, is also…
