Capture and Stability of Resonant Planet Pairs in Turbulent Disk
Linghong Lin, Beibei Liu, Fei Dai +6
We present a theoretical framework for the resonance capture and stability of two-planet systems in turbulent disks. By incorporating stochastic forcing (parameterized by ) alon…
TOI-4495: A Pair of Aligned, Near-Resonant Sub-Neptunes that Likely Experienced Overstable Migration
Mu-Tian Wang, Fei Dai, Hui-Gen Liu +24
We report the discovery of a sub-Neptune and a Neptune-like planet (, ) orbiting the F-type star TOI-449…
Validation of a Third Earth-sized Planet in the TOI-2267 Binary System
Michael Greklek-McKeon, Jonathan Gomez Barrientos, Heather A. Knutson +13
We report the validation of a third terrestrial exoplanet in the nearby (22 pc) TOI-2267 system. TOI-2267 is a binary system with stellar components TOI-2267A (M5, 3030 K) and TOI-…
Unexpected Near-Resonant and Metastable States of Young Multi-Planet Systems
Zhecheng Hu, Fei Dai, Wei Zhu +4
Recent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution…
