Investigation of X-ray timing and spectral properties of ESO 243-49 HLX-1 with long-term Swift Monitoring
Lupin Chun-Che Lin, Chin-Ping Hu, Kwan-Lok Li +5
The long-term Swift monitoring of ESO 243-49 HLX-1 provides an opportunity to investigate the detailed timing and spectral behaviour of this hyper-luminous X-ray source. Swift has…
Evolution of Spin, Orbital, and Superorbital Modulations of 4U 0114+650
Chin-Ping Hu, Yi Chou, C. -Y. Ng +2
We report a systematic analysis of the spin, orbital, and superorbital modulations of 4U 0114+650, a high-mass X-ray binary consists of one of the slowest spinning neutron stars. U…
Mode change of a gamma-ray pulsar, PSR J2021+4026
J. Zhao, C. W. Ng, L. C. C. Lin +8
A glitch of a pulsar is known as a sudden increase in the spin frequency and spin-down rate (frequency time derivative), and it can be caused by a sudden rel\ ease of the stress bu…
Self-Gravitational Force Calculation of Infinitesimally Thin Gaseous Disks on Nested Grids
Hsiang-Hsu Wang, Ronald E. Taam, David C. C. Yen
We extend the work of Yen et al. (2012) and develop 2nd order formulae to accommodate a nested grid discretization for the direct self-gravitational force calculation for infinites…
Self-Gravitational Force Calculation of Second Order Accuracy for Infinitesimally Thin Gaseous Disks in Polar Coordinates
Hsiang-Hsu Wang, David C. C. Yen, Ronald E. Taam
Investigating the evolution of disk galaxies and the dynamics of proto-stellar disks can involve the use of both a hydrodynamical and a Poisson solver. These systems are usually ap…
Hydrodynamical Simulations of the Barred Spiral Galaxy NGC 1097
Lien-Hsuan Lin, Hsiang-Hsu Wang, Pei-Ying Hsieh +3
NGC 1097 is a nearby barred spiral galaxy believed to be interacting with the elliptical galaxy NGC 1097A located to its northwest. It hosts a Seyfert 1 nucleus surrounded by a cir…
