Constraining Dark Matter Density Profiles in UFDs with Wide Binaries: Forecast for the Chinese Space Station Survey Telescope
Yixi Tao, Haijun Tian, Bin Yue +1
The internal structure of dark matter halos on sub-galactic scales remains a key open question, particularly in the context of the core-cusp problem. Ultra-faint dwarf galaxies (UF…
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…
North-South asymmetries in the Galactic thin disk associated with the vertical phase spiral as seen using LAMOST-Gaia stars
Jun Lin, Rui Guo, Sarah A. Bird +5
We select 1,052,469 (754,635) thin disk stars from {\it Gaia} eDR3 and LAMOST DR7 in the range of Galactocentric radius (guiding center radius ) from 8 to 11\,kpc…
Probing the Galactic halo with RR Lyrae stars -- IV. On the Oosterhoff dichotomy of RR Lyrae stars
Shan Zhang, Gaochao Liu, Yang Huang +8
We use 3653 (2661 RRab, 992 RRc) RR Lyrae stars (RRLs) with 7D (3D position, 3D velocity, and metallicity) information selected from SDSS, LAMOST, and Gaia EDR3, and divide the sam…
