Magnetic field strengths of hot giant exoplanets consistent with Solar System values
Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29
Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…
From pre-transit to post-eclipse: investigating the impact of 3D temperature, chemistry, and dynamics on high-resolution emission spectra of the ultra-hot Jupiter WASP-76b
Joost P. Wardenier, Vivien Parmentier, Elspeth K. H. Lee +1
High-resolution spectroscopy has provided a wealth of information about the climate and composition of ultra-hot Jupiters. However, the 3D structure of their atmospheres makes obse…
The Roasting Marshmallows Program with IGRINS on Gemini South V: Atmosphere of MASCARA-1b is Enriched in Refractory Elements
Krishna Kanumalla, Michael R. Line, Martina Chiarella +75
Ultra-hot Jupiters (UHJs; K) enable simultaneous detection of volatile (ice-forming) and refractory (rock-forming) species in planetary atmospheres, provi…
Impact of Clouds on the Atmosphere-Mantle Interface of Sub-Neptunes
Sagnick Mukherjee, Matthew C. Nixon, Luis Welbanks +4
Sub-Neptunes are among the most common type of close-in planets found in our galaxy, yet their bulk composition remains largely uncertain; H-rich envelopes overlaying rocky cores,…
NASA's Pandora SmallSat Mission: Simulated Modeling and Retrieval of Near-Infrared Exoplanet Transmission Spectra
Yoav Rotman, Peter McGill, Luis Welbanks +22
Pandora is a SmallSat mission dedicated to understanding exoplanets and their host stars by disentangling the impact of stellar heterogeneity on exoplanet transmission spectra. Sel…
A Stellar Magnesium to Silicon ratio in the atmosphere of an exoplanet
Jorge A. Sanchez, Peter C. B. Smith, Krishna Kanumalla +17
The elemental compositions of exoplanets encode information about their formation environments and internal structures. While volatile ratios such as carbon-to-oxygen (C/O) are use…
