The angular momentum of stars reflects the relationship between star-forming environment and galactic evolution history
Yu-Fu Shen, Yan Xu, Yi-Bo Wang +3
This study focuses on stars with masses above the Kraft break in the \textit{Kepler} field. Their rotational angular momenta are essentially the same as those at the zero-age main…

Dark energy effects on surface gravitational redshift and Keplerian frequency of neutron stars
Jia-Jing He, Yan Xu, Yi-Bo Wang +3
The research of the properties of neutron stars with dark energy is a particularly interesting yet unresolved problem in astrophysics. We analyze the influence of dark energy on th…
