L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
Denis Defrère, Azzurra Bigioli, Colin Dandumont +34
Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…
wdwarfdate: A Python Package to Derive Bayesian Ages of White Dwarfs
Rocio Kiman, Siyi Xu, Jacqueline K. Faherty +5
White dwarfs have been successfully used as cosmochronometers in the literature, however their reach has been limited in comparison to their potential. We present wdwarfdate, a pub…
Transit timing variations of AU Microscopii b and c
Gy. M. Szabó, Z. Garai, A. Brandeker +76
Here we report large-amplitude transit timing variations (TTVs) for AU\,Microcopii b and c as detected in combined TESS (2018, 2020) and CHEOPS (2020, 2021) transit observations. A…
CWISE J014611.20-050850.0AB: The Widest Known Brown Dwarf Binary in the Field
Emma Softich, Adam C. Schneider, Jennifer Patience +19
While stars are often found in binary systems, brown dwarf binaries are much rarer. Brown dwarf--brown dwarf pairs are typically difficult to resolve because they often have very s…
Let the Great World Spin: Revealing the Stormy, Turbulent Nature of Young Giant Exoplanet Analogs with the Spitzer Space Telescope
Johanna M. Vos, Jacqueline K. Faherty, Jonathan Gagné +5
We present a survey for photometric variability in young, low-mass brown dwarfs with the Spitzer Space Telescope. The 23 objects in our sample show robust signatures of youth and s…
