The EBLM Project - XIX. The absence of radius inflation in a homogeneous analysis of 66 Northern low-mass eclipsing binaries

Yasmin T. Davis, Amaury H. M. J. Triaud, David V. Martin +30

Precise and accurate measurements of host stars are crucial in the search for Earth-like exoplanets, and M-dwarfs are favourable targets in this quest. Low-mass eclipsing binaries…

Dynamically Coupled Three-dimensional Cloud-Chemistry in Rapidly Rotating Irradiated Atmospheres: an Application to the Compact White Dwarf-Brown Dwarf system ZTFJ0038+2030

Yanhong Lai, Xianyu Tan, Daphne Broski-Laing +7

Clouds and disequilibrium chemistry shape the observable properties of substellar and planetary atmospheres, and JWST time-resolved spectroscopy now enables direct tests of their 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…

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…

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…

BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts

Alix V. Freckelton, Daniel Sebastian, Annelies Mortier +29

Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed vie…

PHL 5038AB: Is the brown dwarf causing pollution of its white dwarf host star?

S. L. Casewell, J. Debes, T. J. Dupuy +9

We present new results on PHL 5038AB, a widely separated binary system composed of a white dwarf and a brown dwarf, refining the white and brown dwarf parameters and determining th…

Discovery of a resolved white dwarf-brown dwarf binary with a small projected separation: SDSS J222551.65+001637.7AB

Jenni R. French, Sarah L. Casewell, Trent J. Dupuy +4

We present the confirmation of SDSS J222551.65+001637.7AB as a closely separated, resolved, white dwarf-brown dwarf binary. We have obtained spectroscopy from GNIRS and seeing-limi…
