Locate a stellar flare from the M dwarf LAMOST J1332+5057
Guang-Wei Li, Gui-Ping Zhou, Bing Du +2
Young M-type stars exhibit frequent flares, which would seriously impact their habitable planets. Since stellar surfaces cannot be resolved, flare locations remain unknown. Here, b…
The 3D Architecture of a pair of 6:1 Resonant Brown Dwarfs around the Naked-eye star Ophiuchi
Tianshenhong Sang, Guang-Yao Xiao, Ying-Yi Cao +8
We present a revisiting study of the brown dwarf pair orbiting the naked-eye () K-giant ~Ophiuchi, located only 44\,pc from our Solar system. By jointly analysing archiv…
Cosmic filament spin -- II: filament spin and its impact on galaxy spin-filament alignment in a cosmological simulation
Peng Wang, Xiao-Xiao Tang, Hao-Da Wang +7
Observational studies have reported that cosmic filaments on the megaparsec scale exhibit rotational motion. Subsequent simulation studies have shown qualitative agreement with the…
Cosmic filament spin -- I: a comparative study in observation
Xiao-Xiao Tang, Peng Wang, Wei Wang +3
In the cosmic web, filaments play a crucial role in connecting walls to clusters and also act as an important stage for galaxy formation and evolution. Recent observational studies…
