Difference between quark stars and neutron stars in universal relations and their effect on gravitational waves
Duanyuan Gao, Hao-Jui Kuan, Yurui Zhou +4
We calculate the -mode frequency and tidal overlap of quark stars using the full general relativity method. We verify the universal relations obtained from conventional neutron…

Early photons of GRB 221009A were absorbed by the prompt MeV photons
Duan-yuan Gao, Yuan-Chuan Zou
Gamma-ray burst (GRB) 221009A produced the highest flux of gigaelectronvolt-teraelectronvolt () photons ever observed, allowing the construction of a detailed $\rm TeV…

Jet Lorentz factor constraint for GRB 221009A based on the optical depth of the TeV photons
Duan-yuan Gao, Yuan-Chuan Zou
The recent detection of tera-electronvolt (TeV) photons from the record-breaking gamma-ray burst GRB 221009A during its prompt phase poses challenges for constraining its Lorentz f…
