The Stellar "Snake"-V: the census within 3 kpc in the Solar Neighborhood
Xiang-Ming Yang, Ju-Yong Zhang, Hai-Jun Tian
We present a Gaia DR3 source-level census of \emph{Stellar Snake} complexes within 3\,kpc of the Sun. We define a Stellar Snake as a mutually coherent association of two or more st…
Emergence of a lithium dip in ~35 Myr "Snake" Open Clusters
Yun-Yi Zhang, Hai-Jun Tian, Jian-Rong Shi +2
We report the discovery of a lithium dip (Li-dip) in the stellar "Snake" (age = Myr), challenging the classical view that Li-dips emerge only at ages Myr.…
Wide Binary Evaporation by Dark Solitons: Implications from the GAIA Catalog
Qiming Qiu, Yu Gao, Haijun Tian +3
An analytic calculation is given for binary star evaporation under the tidal perturbation from randomly distributed, spatially extended dark objects. In particular, the Milky Way's…
The Stellar "Snake" -- II: The Mass Function
Xiang-Ming Yang, Sarah A. Bird, Jiadong Li +8
We present a comprehensive investigation on the mass function (MF) of a snake-like stellar structure in the solar neighbourhood, building on our previous discovery. To ensure the r…
