Effect of Central Mass Concentration on the Formation of Nuclear Spirals in Barred Galaxies
Parijat Thakur, H. B. Ann, Ing-Guey Jiang
We have performed smoothed particle hydrodynamics (SPH) simulations to study the response of the central kiloparsec region of a gaseous disk to the imposition of nonaxisymmetric ba…
Self-consistent triaxial de Zeeuw-Carollo Models
Parijat Thakur, Ing-Guey Jiang, Mousumi Das +2
We use the usual method of Schwarzschild to construct self-consistent solutions for the triaxial de Zeeuw & Carollo (1996) models with central density cusps. ZC96 models are triaxi…
On the Mass-Period Distributions and Correlations of Extrasolar Planets
Ing-Guey Jiang, Li-Chin Yeh, Yen-Chang Chang +1
In addition to fitting the data of 233 extra-solar planets with power laws, we construct a correlated mass-period distribution function of extrasolar planets, as the first time in…
On the Dynamics of Resonant Kuiper Belt Objects
Ing-Guey Jiang, Li-Chin Yeh
We propose a new mechanism of drag-induced resonant capture, which can explain the resonant Kuiper Belt Objects in a natural way. A review and comparison with the traditional mecha…
The Modified Restricted Three Body Problems
Ing-Guey Jiang, Li-Chin Yeh
The restricted three body problem is well-known and very important for dynamics of binary, multiple stars and also planetary systems. We extend the classical version of this proble…
The Possible Belts for Extrasolar Planetary Systems
Ing-Guey Jiang, M. Duncan, D. N. C. Lin
More than 100 extrasolar planets have been discovered since 1990s. Different from the solar system, these planets' orbital eccentricities cover a huge range from 0 to 0.7. Incident…
On the Formation of Brown Dwarfs
Ing-Guey Jiang, G. Laughlin, D. N. C. Lin
The observational properties of brown dwarfs pose challenges to the theory of star formation. Because their mass is much smaller than the typical Jeans mass of interstellar clouds,…
On the Chermnykh-Like Problems: II. The Equilibrium Points
Li-Chin Yeh, Ing-Guey Jiang
Motivated by Papadakis (2005a, 2005b), we study a Chermnykh-like problem, in which an additional gravitational potential from the belt is included. In addition to the usual five eq…
On the Chermnykh-Like Problems: I. The Mass Parameter μ=0.5
Ing-Guey Jiang, Li-Chin Yeh
Following Papadakis (2005)'s numerical exploration of the Chermnykh's problem, we here study a Chermnykh-like problem motivated by the astrophysical applications. We find that both…
Data Analysis on the Extra-solar Planets Using Robust Clustering
Ing-Guey Jiang, Li-Chin Yeh, Wen-Liang Hung +1
We use both the conventional and more recently developed methods of cluster analysis to study the data of extra-solar planets. Using the data set with planetary mass M, orbital per…
A Possible Correlation between the Gaseous Drag Strength and Resonant Planetesimals in Planetary Systems
Ing-Guey Jiang, Li-Chin Yeh
We study the migration and resonant capture of planetesimals in a planetary system consisting of a gaseous disc analogous to the primordial solar nebula and a Neptune-like planet.…
The Drag Induced Resonant Capture for Kuiper Belt Objects
Ing-Guey Jiang, Li-Chin Yeh
It has been an interesting question that why there are one-third of Kuiper Belt Objects (KBOs) trapped into the 3:2 resonance but, in contrast, only several KBOs are claimed to be…
On the Formation of Brown Dwarfs
Ing-Guey Jiang, G. Laughlin, D. N. C. Lin
The observational properties of brown dwarfs pose challenges to the theory of star formation. Because their mass is much smaller than the typical Jeans mass of interstellar clouds,…
Dynamical Effects from Asteroid Belts for Planetary Systems
Ing-Guey Jiang, Li-Chin Yeh
The orbital evolution and stability of planetary systems with interaction from the belts is studied using the standard phase-plane analysis. In addition to the fixed point which co…
On the Fate of Close-in Extrasolar Planets
Ing-Guey Jiang, Wing-Huen Ip, Li-Chin Yeh
It has been shown that there is a possible mass-period correlation for extrasolar planets from the current observational data and this correlation is, in fact, related to the absen…
High Velocity Clouds and the Local Group
Kui-Yun Huang, Ing-Guey Jiang
It was proposed by Blitz et al. (1999) that High Velocity Clouds (HVCs) are remnants of Local Group formation and the average distance of HVCs is 1 Mpc, which is the result of a si…
Bifurcation for Dynamical Systems of Planet-Belt Interaction
Ing-Guey Jiang, Li-Chin Yeh
The dynamical systems of planet-belt interaction are studied by the fixed-point analysis and the bifurcation of solutions on the parameter space is discussed. For most cases, our a…
Orbital Evolution of Scattered Planets
Li-Chin Yeh, Ing-Guey Jiang
A simple dynamical model is employed to study the possible orbital evolution of scattered planets and phase plane analysis is used to classify the parameter space and solutions. Ou…
The Size Distribution of the Kuiper Belt Objects
Cheng-Pin Chen, Ing-Guey Jiang
The size distribution is determined directly from the current known Kuiper Belt Objects (KBOs). We found that there is a peak for the size distribution around 230 km in diameter. F…
The Planetary System of Upsilon Andromedae
Ing-Guey Jiang, Wing-Huen Ip
The bright F8 V solar-type star upsilon Andromedae has recently been reported to have a system of three planets of Jovian masses. In order to investigate the orbital stability and…
The Orbit and Mass of the Sagittarius Dwarf Galaxy
Ing-Guey Jiang, James Binney
Possible orbital histories of the Sgr dwarf galaxy are explored. A special-purpose N-body code is used to construct the first models of the Milky Way - Sgr Dwarf system in which bo…
Warps and Cosmic Infall
Ing-Guey Jiang, James Binney
N-body simulations show that when infall reorientates the outer parts of a galactic halo by several degrees per Gyr, a self-gravitating disk that is embedded in the halo develops a…
The Persistence of Warps in Spiral Galaxies with Massive Halos
James Binney, Ing-Guey Jiang, Suvendra Dutta
We study the persistence of warps in galactic discs in the presence of massive halos. A disc is approximated by a set of massive rings, while a halo is represented by a conventiona…
