Effects of Super-rotating Jets on Phase-Resolved Transmission Spectra at High Spectral Resolution
Hayley Beltz, Arjun B. Savel
Hot Jupiter atmospheric circulation can be shaped by a range of processes and planetary parameters, including rotation rate, irradiation gradients from tidal synchronization, magne…
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…
Sub-Neptunes as Soot Factories: Deep Atmosphere Hydrocarbon Formation and Quenching as the Origin of Sub-Neptune Aerosol Trends
Jeehyun Yang, Eliza M. -R. Kempton, Arjun B. Savel
Recent population-level studies of sub-Neptune atmospheres have identified a tentative parabolic trend in transmission spectrum amplitude for planets with Teq ~ 500-800 K. While th…
A gem system with a lava world and a habitable zone sub-Neptune orbiting TOI-1752
A. Peláez-Torres, F. J. Pozuelos, G. Morello +47
The Transiting Exoplanet Survey Satellite (TESS) has delivered a large number of transiting planet candidates around nearby stars by identifying periodic decreases in stellar brigh…
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…
The Roasting Marshmallows Program with IGRINS on Gemini South III: Seeing deeper into the metal depleted atmosphere of a gas-giant on the cusp of the hot to ultra-hot Jupiter transition
Vatsal Panwar, Matteo Brogi, Krishna Kanumalla +17
Ultra-hot Jupiters are a class of gas-giant exoplanets that show a peculiar combination of thermochemical properties in the form of molecular dissociation, atomic ionization, and i…
