Detection and characterisation of binary asteroid candidates through stellar occultations
R. Lallemand, J. Desmars, B. Sicardy +256
Binary asteroids provide key access to fundamental parameters of Solar System remnants and planetary formations. However, the current knowledge of binary asteroids remains strongly…
POSEIDON I: The Dynamical Origins of Transiting Neptunes
Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +17
We present the first results from the POSEIDON survey, aimed at constraining the dynamical origins of transiting Neptunes through stellar obliquity measurements. We report Rossiter…
The Spin-Orbit Alignment of 8 Warm Gas Giant Systems
Juan I. Espinoza-Retamal, Andrés Jordán, Rafael Brahm +9
Essential information about the formation and evolution of planetary systems can be found in their architectures -- in particular, in stellar obliquity () -- as they serve as a…
Candidate Distant Trans-Neptunian Objects Detected by the New Horizons Subaru TNO Survey
Wesley C. Fraser, Simon B. Porter, Lowell Peltier +41
We report the detection of 239 trans-Neptunian Objects discovered through the on-going New Horizons survey for distant minor bodies being performed with the Hyper Suprime-Cam mosai…
HATS-38 b and WASP-139 b join a growing group of hot Neptunes on polar orbits
Juan I. Espinoza-Retamal, Guðmundur Stefánsson, Cristobal Petrovich +9
We constrain the sky-projected obliquities of two low-density hot Neptune planets, HATS-38 b and WASP-139 b, orbiting nearby G and K stars using Rossiter-McLaughlin (RM) observatio…
