Radial velocity follow-up of \textit{Gaia} astrometric substellar companions: six confirmed brown dwarfs and 13 impostor binaries
Marcus L. Marcussen, Simon H. Albrecht, Kamil K. Kalinowski +7
With microarcsecond precision, \textit{Gaia} has made the astrometric discovery of substellar companions feasible. However, follow-up observations are needed to check on orbital so…
Asymmetric Aerosol Distribution on the Terminators of the Warm Saturn WASP-69 b Revealed by JWST NIRISS/SOSS
Le-Chris Wang, Sagnick Mukherjee, Stephen P. Schmidt +16
How aerosols form, are transported, and cycle between condensation and evaporation across exoplanet temperature regimes remains poorly understood. Recent models and observations su…
Observational planning for the 2026 August 5 Falcon 9 Upper Stage lunar impact
Benjamin Fernando, Jennifer Heldmann, Bill Grey +20
On 2026 August 5, at approximately 06:35 UT, a spent Falcon 9 upper stage will impact the lunar surface near Einstein Crater. This event will occur on sunlit terrain near the easte…
Mitigating Charge Migration in JWST NIRISS Reveals That KELT-7 b is a Metal-enriched Ultra-hot Jupiter Orbiting a Young Metal-rich Star
Stephen P. Schmidt, Erin M. May, Joshua D. Lothringer +19
We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We…
Most Hot Jupiters Were Cool Giant Planets for More Than 1 Gyr
Stephen P. Schmidt, Kevin C. Schlaufman
The origin of hot Jupiters is the oldest problem in exoplanet astrophysics. Hot Jupiters formed in situ or via disk migration should be in place just a few Myr after the formation…
Hot Jupiters are Inflated Primarily by Shallow Heating
Stephen P. Schmidt, Daniel P. Thorngren, Kevin C. Schlaufman
The unexpectedly large radii of transiting hot Jupiters have led to many proposals for the physical mechanisms responsible for heating their interiors. While it has been shown that…
