Showing papers in "Vistas in Astronomy in 1988"

TL;DR: Wittmann and Xu as mentioned in this paper compiled a new catalogue of sunspot observations covering the period 165 BC to AD 1684 by updating and merging previously published catalogues and by adding a substantial amount of new data.

TL;DR: In this paper, the physical parameters of star formation in dark clouds have been reviewed, including expanding shock fronts due to newly formed massive stars, gaseous disks surrounding proto stars, the energetic bipolar molecular flows, and the weRlcollimat'ed ionized jets.

TL;DR: In this paper, the authors summarized some of the important results obtained in quantitative studies of the general three-body problem in recent years and presented a collection of these solutions for applications ranging from triple stars to clusters of galaxies.

TL;DR: In this paper, a classification scheme for cancelling magnetic features according to the origins of their two halves is proposed; the observed properties of flux cancellation are summarized; the cancellation appears to be the observational evidence of magnetic reconnection taking place in or above the photospheric layer.

TL;DR: The Parramatta Catalogue as discussed by the authors was the most important work to emanate from this observatory, which was published in 1821 by the new Governor of the colony, Sir Thomas Brisbane.

TL;DR: In this paper, the earliest phase of an emerging flux region on the solar surface is a surge activity, and the magnetic field configuration of the surge region is examined, which suggests that the surges in emerging flux regions are produced by the reconnection between newly-emerging fields and older surrounding magnetic fields.

TL;DR: Yale University was more active in research on meteors than any other institution in America until 1910 as mentioned in this paper, and contributed significantly to the evolution of understanding of meteoric phenomena, from early beliefs that meteors originated in the earth's atmosphere, to theories that fireballs were earth circling satellites, to our current conceptions of the relation between comets, asteroids, and meteors.

TL;DR: The chondritic meteorites display a number of compositional trends, such as the separation of certain lithophile elements from others and separation of siderophiles from non-sidersophiles, which almost certainly reflect nebular processes as discussed by the authors.

TL;DR: The abundances of the light elements, especially Li and Be, are key diagnostics of stellar structure and evolution in cool stars because they are readily destroyed by nuclear reactions in stellar interiors.

TL;DR: In this paper, an etude theorique sur les raies d'emission larges dans les noyaux actifs de galaxies is presented, and un modele semi-consistant is proposed.

TL;DR: In this paper, the intricate processes involved in analyzing a single Voyager image of the rings of Uranus are investigated, showing the presence of numerous new rings not seen in either occultations or images in back scattered light.

TL;DR: In this article, a systematic survey of star formation regions is carried out with the 4m radio telescope at Nagoya University, aiming at obtaining a complete sample of molecular cloud cores and molecular outflows, the J = 1−0 transitions of 12 CO and 13 CO are observed with 3′ resolution unbiased toward any optical signposts of young stars.

TL;DR: In this paper, it was found that the short period anomalies in astronomical time and latitude residuals appeared simultaneously and/or separately preceding major earthquakes occurring in the vicinity of the site of the observations made with classical instruments, and suggested that the anomalies could be caused by some vertical changes due to the motion of the underground mass.

TL;DR: In this paper, the regression of the Martian south polar cap for the 1986 apparition is examined with the measurements of the photographs of Mars obtained at the Bosscha Observatory and at the Hida Observatory.

TL;DR: In this article, a brief review of pre-and post-collapse evolution of globular clusters is given, with particular attention paid to gravothermal oscillations of cores of the clusters.

TL;DR: In this article, the authors considered a two-mode resonant model with the resonance of each mode occurring separately in cavities of the photosphere and chromosphere, and computed resonant periods, transmission spectra and kinetic energy density of the waves associated with the oscillations.

TL;DR: In this paper, the authors show that the nucleus of Comet Halley split into two widely separated nuclei and the projected distance of separation on the plane of the sky is about 5×10 3 km.
