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…
A Link Between Rocky Planet Density and Host Star Chemistry
Aida Behmard, Casey L. Brinkman, Soichiro Hattori +2
Planets and their host stars form from the same cloud of gas and dust, so we assume that their chemical compositions are linked. However, a clear correlation between rocky planet i…
TOI-880 is an Aligned, Coplanar, Multi-planet System
Elina Y. Zhang, Huan-Yu Teng, Fei Dai +22
Although many cases of stellar spin-orbit misalignment are known, it is usually unclear whether a single planet's orbit was tilted or if the entire protoplanetary disk was misalign…
A Hot Jupiter with a Retrograde Orbit around a Sun-like Star and a Toy Model of Hot Jupiters in Wide Binary Star Systems
Steven Giacalone, Andrew W. Howard, Ryan A. Rubenzahl +21
We report an observation of a transit of the hot Jupiter (HJ) KELT-23A b with the Keck Planet Finder spectrograph and a measurement of the sky-projected obliquity () of its Sun-…
Stellar Obliquity of the Ultra-Short-Period Planet System HD 93963
Huan-Yu Teng, Fei Dai, Andrew W. Howard +24
We report an observation of the Rossiter-McLaughlin (RM) effect of the transiting planet HD 93963 Ac, a mini-Neptune planet orbiting a G0-type star with an orbital period of $P_{\r…
TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf
Rena A. Lee, Fei Dai, Andrew W. Howard +71
We report the confirmation of TOI-6324 b, an Earth-sized (1.059 0.041 R) ultra-short-period (USP) planet orbiting a nearby (20 pc) M dwarf. Using the newly com…
Planet Masses, Radii, and Orbits from NASA's K2 Mission
Andrew W. Howard, Evan Sinukoff, Sarah Blunt +50
We report the masses, sizes, and orbital properties of 86 planets orbiting 55 stars observed by NASA's K2 Mission with follow-up Doppler measurements by the HIRES spectrometer at t…
The TESS-Keck Survey XXIV: Outer Giants may be More Prevalent in the Presence of Inner Small Planets
Judah Van Zandt, Erik A. Petigura, Jack Lubin +38
We present the results of the Distant Giants Survey, a three-year radial velocity (RV) campaign to search for wide-separation giant planets orbiting Sun-like stars known to host an…
