Intruder Alert: Breaking Resonant Chains with Planetesimal Flybys
Jiaru Li, Christopher E. O'Connor, Frederic A. Rasio
The orbital architectures of compact exoplanet systems record their complicated dynamical histories. Recent research supports the ``breaking-the-chains'' hypothesis, which proposes…

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b
Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…
