A Deep Search for Exomoons Around WISE 0855 With JWST

Mikayla J. Wilson, Mary Anne Limbach, Andrew J. Skemer +11

JWST is collecting time-series observations of many free-floating planets (FFPs) to study their weather, but these light curves are the ideal datasets to search for exomoons that t…

HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen

Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51

We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…

A Tale of Two Molecules: The Underprediction of CO and Overprediction of PH in Late T and Y Dwarf Atmospheric Models

Samuel A. Beiler, Sagnick Mukherjee, Michael C. Cushing +5

The sensitivity and spectral coverage of JWST is enabling us to test our assumptions of ultracool dwarf atmospheric chemistry, especially with regards to the abundances of phosphin…

Testing the Interaction Between a Substellar Companion and a Debris Disk in the HR 2562 System

Stella Yimiao Zhang, Gaspard Duchêne, Robert J. De Rosa +51

The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interacti…

On the Detection of Exomoons Transiting Isolated Planetary-Mass Objects

Mary Anne Limbach, Johanna M. Vos, Joshua N. Winn +4

All-sky imaging surveys have identified several dozen isolated planetary-mass objects (IPMOs), far away from any star. Here, we examine the prospects for detecting transiting moons…
