Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
Asymmetric nightside CO2 features, inefficient heat transport, and precise evolutionary constraints: Spectroscopic phase curves reveal the past and present of a white dwarf-brown dwarf binary
Daphne Broski-Laing, Yifan Zhou, Joshua D. Lothringer +10
We present the first JWST phase curve of a white dwarf-brown dwarf binary, a NIRSpec PRISM observation of ZTFJ0038+2030. Short-period white dwarf-brown dwarf binaries provide uniqu…
Nautilus Space Observatory: The Evolution of Planets and their Atmospheres
Ilaria Pascucci, Noah Tuchow, Yifan Zhou +11
We are just beginning to explore the billion-year evolution from nascent planets in disks to mature planetary systems. Recent discoveries hint at demographic and atmospheric differ…
Gray Spectral Variability in Three Brown Dwarfs Observed by HST/WFC3 Time-Series Observations
Madalyn F. Chapleski, Yifan Zhou
The L/T transition is a critical evolutionary stage for brown dwarfs and self-luminous giant planets. L/T transition brown dwarfs are more likely to be spectroscopically variable,…
Sensitivity to Sub-Io-sized Exosatellite Transits in the MIRI LRS Lightcurve of the Nearest Substellar Worlds
Andrew Householder, Mary Anne Limbach, Beth Biller +20
JWST's unprecedented sensitivity enables precise spectrophotometric monitoring of substellar worlds, revealing atmospheric variability driven by mechanisms operating across differe…
Seismic Oscillations Excited by Giant Impacts in Directly-Imaged Giant Planets
J. J. Zanazzi, Eugene Chiang, Yifan Zhou
The radii and masses of many giant exoplanets imply their interiors each contain more than 100 of solids. A large metal content may arise when a giant planet grows…
