Approximate equation relevant to axial oscillations on slowly rotating relativistic stars
Yasufumi Kojima, Masayasu Hosonuma
Axial oscillations relevant to the r-mode instability are studied with slow rotation formalism in general relativity. The approximate equation governing the oscillations is derived…

The R-Mode Oscillations in Relativistic Rotating Stars
Yasufumi Kojima, Masayasu Hosonuma
The axial mode oscillations are examined for relativistic rotating stars with uniform angular velocity. Using the slow rotation formalism and the Cowling approximation, we have der…

Boltzmann approach to the large-angle cosmic X-ray background fluctuations
Yasuhiro Miura, Kazuhiro Yamamoto, Kenta Miyauchi +1
Large-angle fluctuations in the cosmic X-ray background are investigated by a new formalism with a simple model of the X-ray sources. Our method is formulated from the Boltzmann eq…
