A Study on the Triggering of Nucleonic Direct Urca Processes in Neutron Stars of Specific Masses and Their Hyperon Dependence
Yan Xu, Yufu Shen, Qi Yuan +2
This work aims to analyze how hyperons affect neutrino radiation properties in nucleonic direct URCA processes, expecting to provide useful references for finding evidence of the e…
IMF slope derived from a pure probabilistic model
Yu-Fu Shen
The stellar initial mass function is of great significance for the study of star formation and galactic structure. Observations indicate that the IMF follows a power-law form. This…
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…
Detecting Outliers in Multiple Sampling Results Without Thresholds
Yu-Fu Shen
Bayesian statistics emphasizes the importance of prior distributions, yet finding an appropriate one is practically challenging. When multiple sample results are taken regarding th…
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…
