The Vertical Structure of Accretion Disks for Dwarf Novae
Autor: Kyu Hong Choi, Kyung Mee Kim
Publikováno v: Journal of Astronomy and Space Sciences, Vol 2, Iss 1, Pp 7-18 (1985)
We have constructed models of steady state accretion disk with accretion rate M=10^16 g/sec or 10^18 g/sec. The mass and the radius of white dwarf were taken as 1 Msolar and 10^9 cm, respectively. The possible application of the results to Z Cha and

Three Body Problem and Formation of Binary System
Autor: Jae Woo Park, Kyu Hong Choi, Kyong Chol Chou
Publikováno v: Journal of Astronomy and Space Sciences, Vol 2, Iss 1, Pp 19-33 (1985)
The singularities of differential Newtonian equation of motion in three body problem cause the loss of accuracy and the considerable increase of the computer time. These singularities could be eliminated during the process of regularization to transf

Variation of Radius Vector of an Artificial Satellite by Cowell's Method
Autor: Jong-Seob Shin, Jae-Woo Park, Kyu Hong Choi
Publikováno v: Journal of Astronomy and Space Sciences, Vol 3, Iss 1, Pp 15-27 (1986)
Variation of radius vector was computed by Cowell's method. Perturbations due to the Sun, moon, and earth's asymmetrical potential are considered. We summarize our results as follow: i) J2 term does not affect the equatorial orbit. ii) Large perturba

Effects of Far-infrared Irradiance at Night on Quality of Sunlight Dried Red Pepper (Capsicum annuum L.) in Plastic Houses
Autor: Kyu-Hong Choi, Guang-Jae Lee, Jung-Beom Yoon, Ki-Yeol Lee, Si-Dong Kim
Publikováno v: Korean Journal of Horticultural Science and Technology. 32:819-826
This study was carried out to investigate the effects of night-time far-infrared irradiance quality of red pepper dried in greenhouses. This study involved 4 treatments: sunlight alone (control), or sunlight plus nightly far-infrared irradiation at 2
