Compensation of the Crossing Angle with Crab Cavities at KEKB (2007)

Abe, T., Akai, K., Akemoto, M., Akiyama, A., Arinaga, M., Ebihara, K., ...

Crab cavities have been installed in the KEKB B--Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab crossing has been...

Measuring Neutron Star Mass and Radius with Three Mass-Radius Relations (2006)

Zhang, C. M., Yin, H. X., Kojima, Y., Chang, H. K., Xu, R. X., Li, X. D., ...

We propose to determine the mass and the radius of a neutron star (NS) using three measurable mass-radius relationships, namely the ``apparent'' radius inferred from neutron star thermal emission,...

We calculated the ellipticity of the deformed star due to the rotation or magnetic field. These two effects are compared to each other within general relativity. It turned out that the magnetic...

Deformation of relativistic magnetized stars (1999)

Konno, K., Obata, T., Kojima, Y.
