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…
The KPF-SLOPE Survey - Small, Compact Multi-Planet Systems Appear Spin-Orbit Aligned
Luke B. Handley, Andrew W. Howard, Fei Dai +16
The angle between stellar spin axes and planetary orbits -- stellar obliquity -- probes the dynamics of planetary migration and evolution. The obliquities of giant planets have bee…
No strong associations between eccentricity and orbital architecture in Kepler compact multis
Gregory J. Gilbert, Erik A. Petigura, Paige M. Entrican
The dynamical history of a planetary system is recorded in the present day architecture of its constituent planets' sizes, orbital periods, and eccentricities. Studying the relatio…
Planetary Architectures of Kepler Compact Multis with Binary Star Companions
Kendall Sullivan, Gregory J. Gilbert
Planets in binary-star systems exhibit demographic differences compared to planets in single-star systems. In particular, planets with binary-star hosts have a lower overall occurr…
A Smooth Transition from Giant Planets to Brown Dwarfs from the Radial Occurrence Distribution
Judah Van Zandt, Greg Gilbert, Steven Giacalone +3
Measuring the occurrence rates of celestial objects is a valuable way to study their origins and evolution. Giant planets and brown dwarfs produce large Doppler signatures that are…
The Transition from Giant Planets to Brown Dwarfs beyond 1 au from the Stellar Metallicity Distribution
Steven Giacalone, Andrew W. Howard, Gregory J. Gilbert +3
Giant planets and brown dwarfs are thought to form via a combination of pathways, including bottom-up mechanisms in which gas is accreted onto a solid core and top-down mechanisms…
