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…
JWST unveils a high mean molecular weight atmosphere for mini-Neptune TOI-1130b: Evidence for formation beyond the water ice line
Saugata Barat, Tyler Fairnington, Shelby Courreges +21
We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R, 19.8 M, K). It is…
Searching for helium escape and a low density atmosphere around the 120 Myr old sub-Neptune HIP94235b using CRIRES+
Ava Morrissey, George Zhou, Chelsea X. Huang +6
Atmospheric mass loss is thought to induce the bimodality in the small planet population as we observe it today. Observationally, active mass loss can be traced by excess absorptio…
Searching for Neutral Hydrogen Escape from the 120 Myr Old Sub-Neptune HIP94235b using HST
Ava Morrissey, George Zhou, Chelsea X. Huang +9
HIP94235 b, a 120 Myr old sub-Neptune, provides us the unique opportunity to study mass loss at a pivotal stage of the system's evolution: the end of a 100 million year (Myr) old p…
