Transmission spectroscopy for the warm sub-Neptune HD3167c: evidence for molecular absorption and a possible high metallicity atmosphere
Thomas Mikal-Evans, Ian J. M. Crossfield, Bjorn Benneke +26
We present a transmission spectrum for the warm (500-600K) sub-Neptune HD3167c obtained using the Hubble Space Telescope Wide Field Camera 3 infrared spectrograph. We combine these…
A New Window into Planet Formation and Migration: Refractory-to-Volatile Elemental Ratios in Ultra-hot Jupiters
Joshua D. Lothringer, Zafar Rustamkulov, David K. Sing +3
A primary goal of exoplanet characterization is to use a planet's current composition to understand how that planet formed. For example, the C/O ratio has long been recognized as c…
Atmosphere Models of Brown Dwarfs Irradiated by White Dwarfs: Analogues for Hot and Ultra-Hot Jupiters
Joshua D. Lothringer, Sarah L. Casewell
Irradiated brown dwarfs (BDs) provide natural laboratories to test our understanding of substellar and irradiated atmospheres. A handful of short-period BDs around white dwarfs (WD…
The PHOENIX Exoplanet Retrieval Algorithm and Using H Opacity as a Probe in Ultra-hot Jupiters
Joshua D. Lothringer, Travis S. Barman
Atmospheric retrievals are now a standard tool to analyze observations of exoplanet atmospheres. This data-driven approach quantitatively compares atmospheric models to observation…
UV Exoplanet Transmission Spectral Features as Probes of Metals and Rainout
Joshua D. Lothringer, Guangwei Fu, David K. Sing +1
The low-resolution transmission spectra of ultra-hot Jupiters observed shortward of 0.5 microns indicate strong absorption at short-wavelengths. Previous explanations have included…
Updated Parameters and a New Transmission Spectrum of HD 97658b
Xueying Guo, Ian J. M. Crossfield, Diana Dragomir +23
Recent years have seen increasing interest in the characterization of sub-Neptune sized planets because of their prevalence in the Galaxy, contrasted with their absence in our sola…
