Atmospheric Signatures of Common Envelope Evolution in White Dwarf Planets
Sydney Jenkins, Andrew Vanderburg, James Mang +4
The majority of confirmed exoplanets orbit within 1 au of a main-sequence (MS) star. When their stellar hosts evolve off the MS, many of these planets will be engulfed and destroye…
Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653
L. Naponiello, E. Poretti, K. Rice +24
The architecture of planetary systems hosting ultra-short-period (USP) planets is a key diagnostic for understanding formation and migration scenarios. The presence of outer giant…
The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters
Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +33
The paper measures how often hot Jupiters have nearby transiting companion planets using TESS data, finding an occurrence rate of about 8%, which informs theories of hot‑Jupiter fo…
Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Federica Rescigno, Manu Stalport, Ancy Anna John +28
We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
The KPF SURFS-UP Survey I: Transmission Spectroscopy of WASP-76 b
Aaron Householder, Fei Dai, Aurora Kesseli +25
We introduce the KPF SURFS-UP (Spectroscopy of the Upper-atmospheres and ReFractory Species in Ultra-hot Planets) Survey, a high-resolution survey to investigate the atmospheric co…
Aerosols and hydrocarbons in the atmosphere of a white dwarf planet
Ryan J. MacDonald, Christopher E. O'Connor, Victoria A. Boehm +15
Most stars, including our Sun, will one day evolve into red giants and, subsequently, white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs, d…
