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…
Helium escaping from the atmosphere of a nearby rocky exoplanet orbiting in a habitable zone
Collin Cherubim, Shreyas Vissapragada, Tim Cunningham +13
Observations of highly irradiated gas giant exoplanets have shown helium escaping from their atmospheres. There is limited evidence for atmospheres on rocky exoplanets, perhaps bec…
Chemodynamical evidence of the HR 1614 moving group as a bar resonance
Andreas J. Koch-Hansen, Vladislav Gulaev, Dominik H. Plonka +4
Moving groups (MGs) are ensembles of disk stars that clump in velocity and action space. A multitude of explanations as to their origin has been attempted, from dissolved star clus…
First Results from WINERED: Detection of Emission Lines from Neutral Iron and a Combined Set of Trace Species on the Dayside of WASP-189 b
Lennart van Sluijs, Emily Rauscher, Eliza M. -R. Kempton +9
Ground and space-based observations have revealed that Ultra Hot Jupiters (UHJs,~) typically have inverted thermal profiles, while cooler hot Jupiters…
Assessing robustness and bias in 1D retrievals of 3D Global Circulation Models at high spectral resolution: a WASP-76 b simulation case study in emission
Lennart van Sluijs, Hayley Beltz, Isaac Malsky +4
High-resolution spectroscopy (HRS) of exoplanet atmospheres has successfully detected many chemical species and is quickly moving toward detailed characterization of the chemical a…
Detailed abundances of the planet-hosting TOI-1173 A/B system: Possible evidence of planet engulfment in a very wide binary
Jhon Yana Galarza, Henrique Reggiani, Thiago Ferreira +7
Over the last decade, studies of large samples of binary systems identified chemical anomalies, and showed that they might be attributed to planet formation or planet engulfment. H…
A High-Resolution Non-Detection of Escaping Helium In The Ultra-Hot Neptune LTT 9779b: Evidence for Weakened Evaporation
Shreyas Vissapragada, Patrick McCreery, Leonardo A. Dos Santos +16
The recent discovery of ``ultra-hot'' ( day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to th…
Insight into the Formation of Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the Pic Moving Group Member HD 181327
Henrique Reggiani, Jhon Yana Galarza, Kevin C. Schlaufman +5
It has been suggested that Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star Pic and therefore the planet'…
