From Misaligned Sub-Saturns to Aligned Brown Dwarfs: The Highest Systems Exhibit Low Obliquities, Even around Hot Stars

Jace Rusznak, Xian-Yu Wang, Malena Rice +1

We present a pattern emerging from stellar obliquity measurements in single-star systems: planets with high planet-to-star mass ratios ( ) -- su…

Single-Star Warm-Jupiter Systems Tend to Be Aligned, Even Around Hot Stellar Hosts: No Dependency

Xian-Yu Wang, Malena Rice, Songhu Wang +22

The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters' tidal detachment likely pre…

SOLES XII. The Aligned Orbit of TOI-2533 b, a Transiting Brown Dwarf Orbiting an F8-type Star

Thiago Ferreira, Malena Rice, Xian-Yu Wang +1

Brown dwarfs occupy a middle ground in mass space between gaseous giant planets and ultra-cool dwarf stars, and the characterisation of their orbital orientations may shed light on…

The SNR of idealised radial velocity signals

David Kipping, Xian-Yu Wang

One of the most basic quantities relevant to planning observations and assessing detection bias is the signal-to-noise ratio (SNR). Remarkably, the SNR of an idealised radial veloc…

Evidence for Primordial Alignment: Insights from Stellar Obliquity Measurements for Compact Sub-Saturn Systems

Brandon T. Radzom, Jiayin Dong, Malena Rice +5

Despite decades of effort, the mechanisms by which the spin axis of a star and the orbital axes of its planets become misaligned remain elusive. Particularly, it is of great intere…

The PFS view of TOI-677 b: A spin-orbit aligned warm Jupiter in a dynamically hot system

Qingru Hu, Malena Rice, Xian-Yu Wang +9

TOI-677 b is part of an emerging class of ``tidally-detached'' gas giants () that exhibit large orbital eccentricities and yet low stellar obliquities. Such s…
