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…
High-Eccentricity Tidal Migration Driven by Secular Chaos in Wide-Binary Systems
Yurou Liu, Hareesh Gautham Bhaskar, Xian-Yu Wang +1
High-eccentricity tidal migration driven by a distant stellar companion offers a natural pathway for producing some hot Jupiters; yet, most theoretical work has relied on an ideali…
A Homogeneous Catalog of Rossiter-McLaughlin Systems: Distinct - Trends in Three Gas-Giant Mass Regimes
Xian-Yu Wang, Songhu Wang, Konstantin Batygin
Stellar obliquity () and orbital eccentricity () trace the dynamical histories of close-in giant planets, but the current observational picture is assembled from heterogeneou…
Unified Kraft Break at ~6500 K: A Newly Identified Single-Star Obliquity Transition Matches the Classical Rotation Break
Xian-Yu Wang, Songhu Wang, J. M. Joel Ong
The stellar obliquity transition, defined by a cut separating aligned from misaligned hot Jupiter systems, has long been assumed to coincide with the rotatio…
Early Evidence for Polar Orbits of Sub-Saturns Around Hot Stars
Emma Dugan, Xian-Yu Wang, Agustin Heron +4
Sub-Saturns have been reported to preferentially occupy near-polar orbits, but this conclusion has so far been based primarily on systems with cool host stars; obliquity measuremen…
Migration and Evolution of giant ExoPlanets (MEEP) II: Super-Jupiters and Lithium-rich Host Stars
Jack Schulte, Joseph E. Rodriguez, David W. Latham +30
Although hot Jupiters were the first exoplanets discovered orbiting main sequence stars, the dominant mechanisms through which they form and evolve are not known. To address the qu…
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…
The OATMEAL Survey. II. The 3D spin-orbit obliquity of an eccentric transiting brown dwarf in the Ruprecht 147 open cluster
Theron W. Carmichael, Steven Giacalone, Noah Vowell +11
We present new analysis of the CWW 89 system as part of the Orbital Architectures of Transiting Massive Exoplanets And Low-mass stars (OATMEAL) survey. The CWW 89 system is a membe…
Evidence for Primordial Alignment II: Insights from Stellar Obliquity Measurements for Hot Jupiters in Compact Multiplanet Systems
Brandon Thomas Radzom, Jiayin Dong, Malena Rice +5
A significant fraction of hot Jupiters have orbital axes misaligned with their host stars' spin axes. The large stellar obliquities of these giants have long been considered potent…
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…
