标题： Viscous damping of r-modes and emission of gravitational waves

摘要： 脉冲星中的Rossby模态（r模）作为稳定的引力波（GW）源已被研究。 研究了刚性地壳对流体核与地壳边界层中粘性阻尼和耗散率的影响。 利用由APR和Skyrme有效相互作用（带有Brussels-Montreal参数组）推导出的状态方程，并用慢速旋转近似，估计了以应变张量幅值表示的辐射引力波强度。 中子星的核心被认为是包含中子、质子、电子和μ子的$\beta$平衡核物质，周围包裹着固态地壳。 针对脉冲星质量谱的广泛范围，计算了临界频率、自转频率的时间演化及其变化率。 显示英文摘要

摘要： The Rossby mode (r-mode) perturbation in pulsars as a steady gravitational wave (GW) source has been explored. The effect of a rigid crust on viscous damping and dissipation rate in the boundary layer between fluid core and crust has been studied. The intensity of the emitted GWs in terms of the strain tensor amplitude has been estimated with the approximation of slow rotation using equation of state derived from the APR and Skyrme effective interactions with Brussels-Montreal parameter sets. The core of the neutron star has been considered to be $\beta$-equilibrated nuclear matter containing neutrons, protons, electrons and muons, surrounded by a solid crust. Calculations have been made for critical frequencies, the time evolution and the rate of change of the spin frequencies across a broad spectrum of pulsar masses.
