On the internal dynamics of starless cores: stability of starless cores with internal motions and collapse dynamics
Young Min Seo, Seung Soo Hong, Yancy L. Shirley
In order to understand the collapse dynamics of observed low-mass starless cores, we revise the conventional stability condition of hydrostatic Bonnor-Ebert spheres to take interna…
Gravitational Instability of Rotating, Pressure-Confined, Polytropic Gas Disks With Vertical Stratification
Jeong-Gyu Kim, Woong-Tae Kim, Young Min Seo +1
We investigate gravitational instability (GI) of rotating, vertically-stratified, pressure-confined, polytropic gas disks using linear stability analysis as well as analytic approx…
AKARI Detection of the Infrared-Bright Supernova Remnant B0104-72.3 in the Small Magellanic Cloud
Bon-Chul Koo, Ho-Gyu Lee, Dae-Sik Moon +12
We present a serendipitous detection of the infrared-bright supernova remnant (SNR) B0104-72.3 in the Small Magellanic Cloud by the Infrared Camera (IRC) onboard AKARI. An elongate…
The Parker Instability in 3-D: Corrugations and Superclouds Along the Carina-Sagittarius Arm
Jose Franco, Jongsoo Kim, Emilio J. Alfaro +1
Here we present three-dimensional MHD models for the Parker instability in a thick magnetized disk, including the presence of a spiral arm. The -field is assumed parallel to the…
The Parker Instability in a Thick Gaseous Disk II: Numerical Simulations in 2D
Alfredo Santillan, Jongsoo Kim, Jose Franco +3
We present 2D, ideal-MHD numerical simulations of the Parker instability in a multi-component warm disk model. The calculations were done using two numerical codes with different a…
A Multi-dimensional Code for Isothermal Magnetohydrodynamic Flows in Astrophysics
Jongsoo Kim, Dongsu Ryu, T. W. Jones +1
We present a multi-dimensional numerical code to solve isothermal magnetohydrodynamic (IMHD) equations for use in modeling astrophysical flows. First, we have built a one-dimension…
The Parker Instability under a Linear Gravity
Jongsoo Kim, Seung Soo Hong, Dongsu Ryu
A linear stability analysis has been done to a magnetized disk under a linear gravity. We have reduced the linearized perturbation equations to a second-order differential equation…
