Stellar companions sculpt hot Jupiter formation and spin-orbit evolution
Cheyanne Shariat, Kareem El-Badry, Songhu Wang +4
Stellar companions can drive hot-Jupiter (HJ) migration and spin-orbit misalignment, but their role in HJ formation remains uncertain. We construct a homogeneous census of resolved…
Predicting Macroturbulence in F/G/K Dwarfs to 100 m/s Precision
Jack Lubin, Erik Petigura, Kento Masuda +6
We leverage the high resolution and spectral stability of the Keck Planet Finder (KPF) spectrograph to investigate macroturbulence broadening via the stellar cross-correlation func…
POSEIDON III: The Aligned Orbit of the Hot Neptune Around the Hot Star WASP-195
Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +33
Stellar obliquities provide important clues as to the formation and migration histories of planetary systems, but measurements remain scarce for Neptune-mass planets, especially th…
Spin-Orbit Alignment of Two Neptune-size Planets Younger than 500 Myr: TOI-560 b and TOI-5082 b
Elina Y. Zhang, Fei Dai, Andrew W. Howard +25
Stellar obliquity measurements provide a direct probe of planetary system dynamics, but remain sparse for Neptune-size planets, particularly at young ages. We present Rossiter-McLa…
Warm Sub-Saturns Orbiting Single Stars Are Spin-Orbit Aligned
Xian-Yu Wang, Songhu Wang
In this work, we show that warm sub-Saturns orbiting single stars are predominantly aligned, in contrast to hot sub-Saturns, which are frequently misaligned, with the two populatio…
