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…
J0404+1112: A 3-Hour Eclipsing White Dwarf-Brown Dwarf Probing Multiple Atmospheric Regimes
J. de Wit, R. Alonso, B. V. Rackham +19
White dwarf-brown dwarf (WD+BD) binaries are rare laboratories for probing both substellar survival through post-main-sequence evolution and the physics of strongly irradiated atmo…
Finding Circumbinary Planets: A Semi-Automated Transit Search of TESS Eclipsing Binaries
Benjamin D. R. Davies, David J. A. Brown, Samuel Gill +1
The discovery of circumbinary planets (CBPs) has advanced our understanding of planet formation and dynamical evolution in complex environments. However, the population of such pla…
New Ultracool Companions to Nearby White Dwarfs
Alexia Bravo, Adam C. Schneider, Sarah Casewell +15
We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and…
The evolutionary history of GD1400, a white dwarf-brown dwarf binary
S. L. Casewell, M. R. Burleigh, R. Napiwotzki +6
GD1400AB was one of the first known white dwarfbrown dwarf binaries, and is the only one of these systems where the white dwarf is a ZZ Ceti pulsator. Here we present both radia…
