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…
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…
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,…
