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…
The Terminator Region Atmosphere of the hot Jupiter WASP-77Ab with ESPRESSO/VLT observations
Zewen Jiang, Wei Wang, Guo Chen +5
Atmospheric studies are essential for elucidating the formation history, evolutionary processes, and atmospheric dynamics of exoplanets. High-resolution transmission spectroscopy o…
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…
