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…
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…
Periodic Variability of the Central Stars of Planetary Nebulae Surveyed through the Zwicky Transient Facility
Pinjian Chen, Xuan Fang, Xiaodian Chen +1
A consensus has been reached in recent years that binarity plays an important role in the formation and evolution of a significant fraction of planetary nebulae (PNe). Utilizing th…
Classification of Periodic Variable Stars from TESS
Xinyi Gao, Xiaodian Chen, Shu Wang +1
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important…
