A Physically Driven Parameterisation of Multidimensional Atmospheres: Application to the JWST Phase Curve of WASP-121b
Yuanheng Yang, Guo Chen, Xianyu Tan +6
Understanding the multidimensional structure of strongly irradiated exoplanets is essential for interpreting their atmospheric dynamics, chemistry and energy transport, yet current…
The capability of CSST in characterizing planetary atmospheres. I. transmission spectroscopy of hot Jupiters
Zibo Liu, Wei Wang, Meng Zhai +9
Transmission spectroscopy has become a primary tool for probing exoplanetary atmospheres, enabling constraints on their chemical compositions and providing limited information on t…
Detection of CO, HO, and OH in WASP-18b with JWST/NIRISS using Direct-Extracted Spectra and Cross-Correlation
Qinglin Ouyang, Fei Yan, Shuo Liu +7
The James Webb Space Telescope (JWST) has revolutionized the characterization of exoplanetary atmospheres, offering unprecedented sensitivity to probe their chemical and physical p…
Optical transmission spectrum of HAT-P-47b: evidence for aerosols and tentative TiO absorption
Wan-Hao Wang, Guo Chen, Fei Yan +5
Transmission spectroscopy enables the characterization of exoplanet atmospheres by probing absorption features in their terminator regions. In the optical, it is particularly sensi…
An Old, Low-mass, Metal-poor Hypervelocity Star Candidate Consistent with a Galactic Center Origin
Shunhong Deng, Yang Huang, Haozhu Fu +4
We report the discovery of DESI-HVS1, a hypervelocity star (HVS) candidate identified from DESI DR1 spectroscopy and Gaia DR3 astrometry. DESI-HVS1 is an old, low-mass, metal-poor…
Thermal emission spectra of the ultra-hot Jupiter WASP-33 b
Qianyi Zou, Meng Zhai, Wei Wang +12
Observations of exoplanetary atmospheres provide critical insights into their chemical composition, formation and evolution history. Ultra-hot Jupiters serve as excellent targets f…
