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…
SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA): Atmospheric and Fundamental Parameters of Ultracool Dwarfs
Zhijun Tu, Shu Wang, Haomiao Huang +2
We present the SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA), a homogeneous sample of 1675 field ultracool dwarfs with continuous 0.75--5~m spectrophotometry from SPHE…
A Morpho-kinematic Study of Galactic High-ADF PNe Based on the VLT/UVES Deep Spectroscopy
Haomiao Huang, Xuan Fang, Jorge Garcia-Rojas +3
We report detailed analyses of deep, high-resolution spectra of three Galactic planetary nebulae (PNe) with high abundance discrepancy factors (ADFs), Hf2-2, M1-42 and NGC6153, obt…
PyEMILI: A New Generation Computer-aided Spectral Line Identifier -- II. Emission-line Identification and Plasma Diagnostics of a Sample of Gaseous Nebulae
Zhijun Tu, Xuan Fang, Jorge García-Rojas +2
In order to test the robustness and reliability of the new generation spectral-line identifier PyEMILI, as initially introduced in Paper I, in line identification and establish a r…
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…
The Mini-SiTian Array: first-two-year operation
Min He, Hong Wu, Liang Ge +70
The SiTian project, designed to utilize 60 telescopes distributed across multiple sites in China, is a next-generation time-domain survey initiative. As a pathfinder for the SiTian…
Three Brown Dwarfs Masquerading as High-Redshift Galaxies in JWST Observations
Zhijun Tu, Shu Wang, Xiaodian Chen +1
We report the spectroscopic identification of three brown dwarf candidates -- o005_s41280, o006_s00089, and o006_s35616 -- discovered in the RUBIES using James Webb Space Telescope…
PyEMILI: A New Generation Computer-aided Spectral Line Identifier
Zhijun Tu, Xuan Fang, Robert Williams +1
Deep high-dispersion spectroscopy of Galactic photoionized gaseous nebulae, mainly planetary nebulae and HII regions, has revealed numerous emission lines. As a key step of spectra…
A Multi-station Meteor Monitoring (M) System. II. system upgrade and a pathfinder network
Z. Li, H. Zou, J. Liu +10
Meteors are important phenomenon reflecting many properties of interplanetary dust particles. The study of their origin, mass distribution, and orbit evolution all require large da…
A Multi-station Meteor Monitoring (M) System. I. Design and Testing
Z. Li, H. Zou, J. Liu +8
Meteors carry important and indispensable information about the interplanetary environment, which can be used to understand the origin and evolution of our solar system. We have de…
Physical Parameters and Properties of 20 Cold Brown Dwarfs in JWST
Zhijun Tu, Shu Wang, Jifeng Liu
We present a comprehensive analysis of 20 T and Y dwarfs using spectroscopy from the NIRSpec CLEAR/PRISM and MIRI LRS instruments on the James Webb Space Telescope. To characterize…
