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…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Scattering of stellar-mass black holes and gravitational wave bremsstrahlung radiation in AGN disks
Peter Lott, Christian Faulhaber, Joshua Brandt +3
Dynamics of stellar mass black holes (sBHs) embedded in active galactic nuclei (AGNs) could produce highly eccentric orbits near the central supermassive black hole, leading to rep…
Properties of Free Floating Planets Ejected through Planet-Planet Scattering
Hareesh Gautham Bhaskar, Hagai Perets
Multiple studies have shown that planet-planet scattering plays an important role in the dynamical evolution of planetary systems. For instance, it has been shown that planet-plane…
TOI-6038 A b: A dense sub-Saturn in the transition regime between the Neptunian ridge and savanna
Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13
We present the discovery and characterization of a sub-Saturn exoplanet, TOI-6038~A~b, using the PARAS-2 spectrograph. The planet orbits a bright (), metal-rich late F-typ…
