We study the dimensionless spin parameter j ≡ c J/(GM2) of different kinds of uniformly rotating compact stars, including traditional neutron stars, hyperonic
We measure the distance to the supernova remnant G15.4+0.1 which is likely associated with Te V source HESS J1818–154. We build the neutral hydrogen(HI) absorp
In order to study the potential associated with high precision CCD astrometry of irregular satellites, we have acquired experimental observations of Himalia, th
This paper addresses the improved science resulting from joint observations performed by the different instruments onboard the Advanced Space-based Solar Observ
