Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
Learning about Treatment Effects in Panels under Unknown Interference
Shengbin Wei
When comparison units may also respond to treatment, panel comparisons reflect both the treatment effect and spillovers. If the interference pattern is unknown, observed outcomes a…
KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c
Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16
While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…
KRONOS II: Solar-like Umbra and Penumbra Properties on the Young Sun V1298~Tau
Matthew M. Murphy, Adina D. Feinstein, Meir E. Schochet +14
Transiting exoplanets provide a unique laboratory for studying stellar surface heterogeneities via starspot or facular occultations. When observed at multiple wavelengths, this con…
The Days Drag On on WASP-121 b: Interpreting its NIRISS Spectroscopic Phase Curve with General Circulation Models
Robert C. Frazier, Emily Rauscher, Jared Splinter +18
Ultra-hot Jupiters present extreme atmospheric phenomena not found in the Solar System. These planets' daysides experience strong temperature inversions, molecular species (includi…
On the Information Content of Ariel Transmission Spectra: Reassessing the Tier System
Michael Radica, Nicolas B. Cowan, Ryan Cloutier +1
The European Space Agency's Ariel mission will conduct a survey of the atmospheric properties of exoplanets around bright stars. The mission is nominally divided into three Tiers.…
