The Illusory Precision of TTV Masses: Hidden Solutions Behind Kepler-9's Tight Mass Ratio
Sheng Jin, Dong-Hong Wu, Xiao-Ling Xu +1
Transit timing variations (TTV) are considered a tool for constraining the masses of transiting planets in the absence of radial-velocity data. Although theoretical studies have lo…
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…
Dynamical Origin of (469219) Kamo`oalewa of Tianwen-2 Mission from the Main-Belt: Secular Resonance, Flora Family or 3:1 Resonance with Jupiter
Yandong Wang, Shoucun Hu, Jianghui Ji +1
China's Tianwen-2 mission, launched on 29 May 2025, targets the near-Earth object (469219) Kamo`oalewa, an Earth quasi-satellite trapped in a 1:1 mean-motion resonance with our pla…
The Formation of Ultra-short-period Planets under the Influence of the Nearby Planetary Companions
Jia Jun Zhu, Su Wang, Jianghui Ji +1
Ultra-short-period (USP) planets, defined as those with orbital periods shorter than 1 day, provide valuable insights into planetary evolution under strong stellar tidal interactio…
Discovery and dynamics of a Sedna-like object with a perihelion of 66 au
Ying-Tung Chen, Patryk Sofia Lykawka, Yukun Huang +30
Trans-Neptunian objects (TNOs) with large perihelion distances ( au) and semi-major axes ( au) provide insights into the early evolution of the solar system and th…
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…
Asymmetry and Dynamical Constraints in 2-Limbs Retrieval of WASP-39 b Inferring from JWST Data
Zixin Chen, Jianghui Ji, Guo Chen +2
Transmission spectroscopy has provided unprecedented insight into the makeup of exoplanet atmospheres. A transmission spectrum contains contributions from a planet's morning and ev…
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…
Formation of Ultra-short-period Planet in Hot Jupiter Systems: Application to WASP-47
Su Wang, Mengrui Pan, Yao Dong +2
The WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as…
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…
Evidence for Nightside Water Emission Found in Transit of Ultrahot Jupiter WASP-33b
Yuanheng Yang, Guo Chen, Fei Yan +2
To date, the dayside thermal structure of ultrahot Jupiters (UHJs) is generally considered to be inverted, but their nightside thermal structure has been less explored. Here we exp…
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…
Forming Giant Planets Around Late-M Dwarfs: Pebble Accretion and Planet-Planet Collision
Mengrui Pan, Beibei Liu, Anders Johansen +6
We propose a pebble-driven core accretion scenario to explain the formation of giant planets around the late-M dwarfs of . In order to explore th…
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,…
