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…
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…
Direct Imaging for the Debris Disk around Eridani with the Cool-Planet Imaging Coronagraph
Chunhui Bao, Jianghui Ji, Gang Zhao +4
We analyze the inner debris disk around Eridani using simulated observations with the Cool-Planet Imaging Coronagraph (CPI-C). Using the radiative transfer code MCFOST, we gene…
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…
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…
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…
CHES: a space-borne astrometric mission for the detection of habitable planets of the nearby solar-type stars
Jianghui Ji, Haitao Li, Junbo Zhang +19
The Closeby Habitable Exoplanet Survey (CHES) mission is proposed to discover habitable-zone Earth-like planets of the nearby solar-type stars ( away from our…
Dynamical evolution and stability maps of the Proxima Centauri system
Tong Meng, Jianghui Ji, Yao Dong
Proxima Centauri was recently discovered to host an Earth-mass planet of Proxima b, and a 215-day signal which is probably a potential planet c. In this work, we investigate the dy…
Tidal Evolution of Kepler lower-mass Planets
Yao Dong, Jianghui Ji, Su Wang
The planets with a radius 4 observed by the Kepler mission exhibit a unique feature, and propose a challenge for current planetary formation models. The tidal effe…
