Milky Way Mass Through Escape Velocity Curve from LAMOST K Giants
Yin Wu, Haining Li, Yang Huang +2
Escape velocity has long been used to constrain the mass of the Dark Matter (DM) halo in the Milky Way (MW). Here we present a study of the escape velocity curve using a sample of…
Unveiling Galactic substructures with M Giant stars: A kinematic and chemical study based on LAMOST DR9, Gaia DR3 and APOGEE DR17
Longfei Ding, Jing Li, Xiang-Xiang Xue +3
Based on the updated M giant star catalog selected from LAMOST DR9, we iden-tify substructures within the integrals-of-motion space through Friends-of-Friends cluster-ing algorithm…
An Actinide-boost Star Discovered in the Gaia-Sausage-Enceladus
Yangming Lin, Haining Li, Ruizheng Jiang +6
We report the discovery of an actinide-boost, very metal-poor (), -process-enhanced () star, LAMOST J0804+5…
The Impact of Neutrino Magnetic Moments on the Evolution of the Helium Flash and Lithium-Rich Red Clump Stars
Xizhen Lu, Chunhua Zhu, Guoliang Lü +3
The detection of the neutrino magnetic moment (NMM,) is one of the most significant challenges in physics. The additional energy loss due to NMM can significantly influence t…
