Neptune migration model with one extra planet
Lun-Wen Yeh, Hsiang-Kuang Chang
We explore conventional Neptune migration model with one additional planet of mass at 0.1-2.0 Me. This planet inhabited in the 3:2 mean motion resonance with Neptune during planet…
Nodeless differentially rotational Alfvén oscillations of crustal solid-state plasma in quaking neutron star
S. I. Bastrukov, H. -K. Chang, I. V. Molodtsova +1
The two-component, core-crust, model of a neutron star with homogenous internal and dipolar external magnetic field is studied responding to quake-induced perturbation by substanti…
Fundamental vibrational mode in a highly inhomogeneous star
S. I. Bastrukov, H. -K. Chang, E. -H. Wu +1
The eigenfrequency problem of fundamental vibrational mode in a highly inhomogeneous star, modeled by self-gravitating mass of viscous liquid with singular density at the center, i…
Torsional nodeless vibrations of quaking neutron star restored by combined forces of shear elastic and magnetic field stresses
S. I. Bastrukov, G. -T. Chen, H. -K. Chang +2
Within the framework of Newtonian magneto-solid-mechanics, relying on equations appropriate for a perfectly conducting elastic continuous medium threaded by a uniform magnetic fiel…
Computation of Neutron Star Surface Emission Spectra for Arbitrary Magnetic Field Directions without Diffusion Approximation
L. W. Yeh, G. T. Chen, H. K. Chang
To derive physical properties of the neutron star surface with observed spectra, a realistic model spectrum of neutron star surface emission is essential. Limited by computing reso…
