Transiting Planetary Systems with Distant Giant Companions Remain Moderately Coplanar
Guang-Yao Xiao, Huan-Yu Teng, Xiumin Huang +4
The mutual inclination between inner planets and distant giant companions provides an important probe of planetary system formation and dynamical evolution, yet direct measurements…
Dynamical Mass Demography of Single S-type Planets Shaped by Stellar Companions
Xiumin Huang, Jianghui Ji
More than 700 S-type planets have been identified from Gaia and TESS observations, including over 150 transiting targets, enabling the precise dynamical orbits and planetary mass c…
Closeby Habitable Exoplanet Survey (CHES). V. Planetary Parameters Derived from Angular Separation Variations
Dongjie Tan, Jianghui Ji, Chunhui Bao +11
The Closeby Habitable Exoplanet Survey (CHES) aims to achieve microarcsecond-level astrometry of about one hundred nearby FGK-type stars within 10 parsecs to detect Earth-like plan…
Closeby Habitable Exoplanet Survey (CHES). IV. Synergy between astrometry and direct imaging missions of the Habitable World Observatory for detecting Earth-like planets
Chunhui Bao, Jianghui Ji, Dongjie Tan +4
The detection and characterization of habitable planets around nearby stars persist as one of the foremost objectives in contemporary astrophysics. This work investigates the syner…
Closeby Habitable Exoplanet Survey (CHES). III. Retrieval of Planetary Masses in Binaries Using the N-body Model with RV and Astrometry Synergy
Xiumin Huang, Jianghui Ji, Chunhui Bao +4
Given that secular perturbations in a binary system not only excite high orbital eccentricities but also alter the planetary orbital inclination, the classical Keplerian orbital mo…
Closeby Habitable Exoplanet Survey (CHES). II. An Observation Strategy for the Target Stars
Dongjie Tan, Jianghui Ji, Chunhui Bao +11
The Closeby Habitable Exoplanet Survey (CHES) constitutes a mission intricately designed to systematically survey approximately 100 solar-type stars located within the immediate pr…
Closeby Habitable Exoplanet Survey (CHES). I. Astrometric Noise and Planetary Detection Efficiency due to Stellar Spots and Faculae
Chunhui Bao, Jianghui Ji, Dongjie Tan +4
The Closeby Habitable Exoplanet Survey (CHES) is dedicated to the astrometric exploration for habitable-zone Earth-like planets orbiting solar-type stars in close proximity, achiev…
PyMsOfa: A Python Package for the Standards of Fundamental Astronomy (SOFA) Service
Jianghui Ji, Dongjie Tan, Chunhui Bao +4
The Standards of Fundamental Astronomy (SOFA) is a service provided by the International Astronomical Union (IAU) that offers algorithms and software for astronomical calculations,…
Evolution of the Planetary Obliquity: The Eccentric Kozai-Lidov Mechanism Coupled with Tide
Xiumin Huang, Jianghui Ji, Shangfei Liu +2
The planetary obliquity plays a significant role in determining physical properties of planetary surfaces and climate. As direct detection is constrained due to the present observa…
Extremely Inclined Orbit of S-type Planet Cep Ab Induced by Eccentric Kozai-Lidov Mechanism
Xiumin Huang, Jianghui Ji
Cep Ab is a typical S-type planet, which occupies a nearly perpendicular planetary orbit relative to the binary. Here we use the Markov Chain Monte Carlo (MCMC) sampler to cond…
The von Zeipel-Lidov-Kozai effect inside mean motion resonances with applications to trans-Neptunian objects
Hanlun Lei, Jian Li, Xiumin Huang +1
Secular dynamics inside MMRs plays an essential role in governing the dynamical structure of the trans-Neptunian region and sculpting the orbital distribution of trans-Neptunian ob…
Quadrupole and octupole order resonances in non-restricted hierarchical planetary systems
Hanlun Lei, Xiumin Huang
Nonrestricted hierarchical three-body configurations are common in various scales of astrophysical systems. Dynamical structures of the quadrupole-order resonance (the von Zeipel-L…
