The only inflated brown dwarf in an eclipsing white dwarf-brown dwarf binary: WD1032+011B
Jenni R. French, Sarah L. Casewell, Rachael C. Amaro +9
Due to their short orbital periods and relatively high flux ratios, irradiated brown dwarfs in binaries with white dwarfs offer better opportunities to study irradiated atmospheres…
Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e
Quanyi Liu, Wei Zhu, Yifan Zhou +5
Planets may be rotationally flattened, and their oblateness thus provide useful information on their formation and evolution. Here we develop a new algorithm that can compute the t…
Atmospheric Retrievals of the Phase-resolved Spectra of Irradiated Brown Dwarfs WD-0137B and EPIC-2122B
Joshua D. Lothringer, Yifan Zhou, Daniel Apai +3
We present an atmospheric retrieval analysis of HST/WFC3/G141 spectroscopic phase curve observations of two brown dwarfs, WD-0137B and EPIC-2122B, in ultra-short period orbits arou…
Time-resolved Hubble Space Telescope Wide Field Camera 3 Spectrophotometry Reveals Inefficient Day-to-Night Heat Redistribution in the Highly Irradiated Brown Dwarf SDSS 1557B
Rachael C. Amaro, Daniel Apai, Ben W. P. Lew +8
Brown dwarfs in ultra-short period orbits around white dwarfs offer a unique opportunity to study the properties of tidally-locked, fast rotating (1-3 hr), and highly-irradiated at…
Deep Pa Imaging of the Candidate Accreting Protoplanet AB Aur b
Lauren I. Biddle, Brendan P. Bowler, Yifan Zhou +2
Giant planets grow by accreting gas through circumplanetary disks, but little is known about the timescale and mechanisms involved in the planet assembly process because few accret…
Revisiting the Helium and Hydrogen Accretion Indicators at TWA 27B: Weak Mass Flow at Near-Freefall Velocity
Gabriel-Dominique Marleau, Yuhiko Aoyama, Jun Hashimoto +1
TWA 27B (2M1207b) is the first directly-imaged planetary-mass (MP ~ 5 MJ) companion (Chauvin et al. 2004) and was observed at 0.9--5.3 micron with JWST/NIRSpec (Luhman et al. 2023)…
