SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA): Atmospheric and Fundamental Parameters of Ultracool Dwarfs
Zhijun Tu, Shu Wang, Haomiao Huang +2
The paper presents the SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA), a homogeneous dataset of 1675 field ultracool dwarfs with continuous 0.75–5 µm spectra, and derives…
A Search for Variability of Ultracool Dwarfs with the Zwicky Transient Facility
Haomiao Huang, Shu Wang, Xiaodian Chen +2
Rotationally modulated photometric variability of ultracool dwarfs encodes key information about cloud structure and temperature contrasts. Large homogeneous optical datasets are c…
The Phenomenological Classification of TESS Eclipsing Binaries
Shi-Qi Liu, Kai Li, Xiao-Dian Chen +1
Eclipsing binaries are crucial astrophysical laboratories for studying stellar parameters and evolutionary processes. In this study, we constructed a machine-learning-based model f…
StarCLR: Contrastive Learning Representation for Astronomical Light Curves
Junyao Ding, Xiaodian Chen, Xinyi Gao +7
With the rapid development of time-domain surveys, the availability of massive light curve data offers new opportunities for studying stellar evolution and variable star classifica…
The Dependence of the Extinction Coefficient on Reddening for Galactic Cepheids
Huajian Wang, Xiaodian Chen, Shu Wang
Cepheids are fundamental distance indicators, playing a crucial role not only in the cosmic distance ladder but also in mapping the structure, kinematics, and extinction properties…
A Large Sample of JWST/NIRSpec Brown Dwarfs: New Distant Discoveries
Zhijun Tu, Shu Wang, Xiaodian Chen +1
Brown dwarfs are essential probes of stellar and planetary formation, yet their low luminosities pose challenges for detection at large Galactic distances. The James Webb Space Tel…
