Non-principal axis rotation in binary asteroid systems and how it weakens the BYORP effect
Alice C. Quillen, Anthony LaBarca, YuanYuan Chen
Using viscoelastic mass/spring model simulations, we explore tidal evolution and migration of compact binary asteroid systems. We find that after the secondary is captured into a s…
Transiting Exoplanet Monitoring Project (TEMP). IV. Refined System Parameters, Transit Timing Variations and Orbital Stability of the Transiting Planetary System HAT-P-25
Xian-Yu Wang, Songhu Wang, Tobias C. Hinse +12
We present eight new light curves of the transiting extra-solar planet HAT-P-25b obtained from 2013 to 2016 with three telescopes at two observatories. We use the new light curves,…
Impact Excitation of a Seismic Pulse and Vibrational Normal Modes on Asteroid Bennu and Associated Slumping of Regolith
Alice C. Quillen, Yuhui Zhao, YuanYuan Chen +3
We consider an impact on an asteroid that is energetic enough to cause resurfacing by seismic reverberation and just below the catastrophic disruption threshold, assuming that seis…
Transiting Exoplanet Monitoring Project (TEMP). III. On the Relocation of the Kepler-9~b Transit
Songhu Wang, Dong-Hong Wu, Brett C. Addison +24
The Kepler-9 system harbors three known transiting planets. The system holds significant interest for several reasons. First, the outer two planets exhibit a period ratio that is c…
Tilting Styx and Nix but not Uranus with a Spin-Precession-Mean-motion resonance
Alice C. Quillen, Yuan-Yuan Chen, Benoit Noyelles +1
A Hamiltonian model is constructed for the spin axis of a planet perturbed by a nearby planet with both planets in orbit about star. We expand the planet-planet gravitational poten…
Obliquity evolution of the minor satellites of Pluto and Charon
Alice C. Quillen, Fiona Nichols-Fleming, Yuan-Yuan Chen +1
New Horizons mission observations show that the small satellites Styx, Nix, Kerberos and Hydra, of the Pluto-Charon system, have not tidally spun-down to near synchronous spin stat…
The effect of orbital damping during planet migration on the Inclination and Eccentricity Distributions of Neptune Trojans
Yuan-Yuan Chen, Yuehua Ma, Jiaqing Zheng
We explore planetary migration scenarios for formation of high inclination Neptune Trojans (NTs) and how they are affected by the planetary migration of Neptune and Uranus. If Nept…
How to reach the orbital configuration of the inner three planets in HD 40307 Planet System ?
Chen Yuan-Yuan, Zhou Ji-Lin, Ma Yue-Hua
The formation of the present configuration of three hot super-Earths in the planet system HD 40307 is a challenge to dynamical astronomers. With the two successive period ratios bo…
A Mechanism of Exciting Planetary Inclination and Eccentricity through a Residual Gas Disk
Yuan-Yuan Chen, Hui-Gen Liu, Gang Zhao +1
Accordling to the theory of Kozai resonance, the initial mutual inclination between a small body and a massive planet in an outer circular orbit is as high as fo…
