Secular Excitation of Polar Neptune Orbits in Pure Disk-Planet Systems

Luke B. Handley, Konstantin Batygin

The stellar spin-orbit angles of Neptune-sized planets present a primordial yet puzzling view of the planetary formation epoch. The striking dichotomy of aligned and perpendicular…

TOI-4495: A Pair of Aligned, Near-Resonant Sub-Neptunes that Likely Experienced Overstable Migration

Mu-Tian Wang, Fei Dai, Hui-Gen Liu +24

We report the discovery of a sub-Neptune and a Neptune-like planet (, ) orbiting the F-type star TOI-449…

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…

Orbital Eccentricities Suggest a Gradual Transition from Giant Planets to Brown Dwarfs

Gregory J. Gilbert, Judah Van Zandt, Erik A. Petigura +3

To date, hundreds of sub-stellar objects with masses between have been detected orbiting main-sequence stars. The current convention uses the deuterium-burning…

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-…
