Nova Aquilae 1982 was observed spectroscopically and photometrically in January, February, and April 1982. The results of these observations including those obtained a few days after the discovery, are presented.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

We madeN-body simulation of Giant Molecular Clouds in a model galaxy and confirmed that their random motion is generated and accelerated by purely gravitational interaction among them in some 107–8 yr. The results of the present simulation agree well with those of the previous theoretical calculation by Fukunaga (1984a, b).Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

The response by a gaseous disc to perturbations is investigated. Spectral analysis of the resulting pattern indicates that information about the nature of the perturber is maintained only if the perturbation is strong.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

The growth of thermal-chemical instability in a pre-galactic medium is followed by numerical simulation of gas dynamics. Results show that a primordial gas cloud breaks into self-gravitating subcondensations with the mass of normal stars.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

High resolution profiles of permitted and forbidden lines in symbiotic stars are described, with particular reference to the broad wings. An interpretation of the data in terms of an optically thin accretion disc around a hot subdwarf is presented.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

The optical light variation of the nucleus of the galaxy NGC 4151 was monitored mainly using the 74 inch telescope of the Helwan Observatory, Egypt.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

The night-to-night and short-term variations inUBV light curves of EW Lac which were made during 1982–1984 at Yonsei University Observatory are discussed. The long-term variability in the photometric behaviour of the star is examined with our own data as well as those of Harmanecet al. (1980).Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984.Yonsei University Observatory Contribution No. 23. 相似文献

Preliminary results of a program to identify optically a sample of flat spectrum radio sources are described. The identifications are based only on positional coincidences, and have yielded at least one object with a very high redshift.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

For studying modal coupling, we ran the hydrodynamic models of cepheids and observed the growth and disappearance of various modes in their pulsation. The existence of modal coupling has been confirmed.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

The direct measurement of the height of the radio source above a solar active region was done by the Westerbork Synthesis Radio Telescope when the source crossed the west limb. The height of the brightest part was 12000 km above the limb. The result of the disk observation is also presented and the emission mechanisms of the observed sources are discussed.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献

Evidence is presented indicating the non-random alignment of spiral galaxies in the Local Supercluster. The form of this effect is such that the spin angular momentum vectors of intermediate-type spirals are coherently aligned in space. The results suggest the formation of galaxies in the Local Supercluster according to the fragmentation hypothesis.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984. 相似文献
