WINERED Detects a Strong Atmospheric Outflow on the Sub-Neptune GJ 3090b
Shreyas Vissapragada, Zifan Lin, Annabella Meech +12
Sub-Neptunes are the most common short-period ( d) planets known. A major goal for the field is to build a comprehensive understanding of their compositions and evolutionary…
Stringent Upper Bounds on Atmospheric Mass Loss from Three Neptune-Sized Planets in the TOI-4010 System
Morgan Saidel, Shreyas Vissapragada, Michael Zhang +6
Photoevaporative models predict that the lower edge of the Neptune desert is sculpted by atmospheric mass loss. However, the stellar high energy fluxes that power hydrodynamic esca…
Strong NUV Refractory Absorption and Dissociated Water in the Hubble Transmission Spectrum of the Ultra Hot Jupiter KELT-20 b
Yayaati Chachan, Joshua Lothringer, Julie Inglis +8
Ultra hot Jupiters (UHJs) present a promising pathway for drawing a link between a planet's composition and formation history. They retain both refractory and volatiles species in…
A Global Perspective with Updated Constraints on the Ultra-hot Jupiter WASP-19b: Atmospheric Properties and Stellar Activity
Abigail A. Tumborang, Jessica J. Spake, Heather A. Knutson +7
We present a detailed reanalysis of the atmospheric properties of WASP-19b, an ultra-hot Jupiter (1.14 M Jup, 1.41 R Jup) orbiting an active Sun-like star every 0.79 day. We reanal…
Atmospheric Mass Loss from TOI-1259 A b, a Gas Giant Planet With a White Dwarf Companion
Morgan Saidel, Shreyas Vissapragada, Jessica Spake +6
The lack of close-in Neptune-mass exoplanets evident in transit surveys has largely been attributed either to photoevaporative mass loss or high-eccentricity migration. To distingu…
Using helium 10830 Å transits to constrain planetary magnetic fields
Ethan Schreyer, James E. Owen, Jessica J. Spake +2
Planetary magnetic fields can affect the predicted mass loss rate for close-in planets that experience large amounts of UV irradiation. In this work, we present a method to detect…
