1958 Publications of the Astrophysical Observatory

This series, Smithsonian Contribution* to Astrophysics, was inaugurated in 1956 to provide a proper communication for the results of research con- ducted at the Astrophysical Observatory of the Smithsonian Institution. Its purpose is the "increase and diffusion of knowledge" in the field of astrophysics, with particular emphasis on problems of the sun, the earth, and the solar system. Its pages are open to a limited number of papers by other investigators with whom we have common interests. Another series is Annals of the Astrophysical Observatory. It was started In 1900 by the Observatory's first director, Samuel P. Langley, and has been published about every 10 years since that date. These quarto volumes, some of which are still available, record the history of the Observatory's researches and activities. Many technical papers and volumes emanating from the Astrophysical Observatory have appeared in the Smithsonian Miscellaneous Collections. Among these are Smithsonian Physical Tables, Smithsonian Meteorological Tables, and World Weather Records. Additional information concerning these publications may be secured from the Editorial and Publications Division, Smithsonian Institution, Washington, D. G. FEED L.

[a, /S, y, i Lib], the other covering Fang. On the 3d cyclical day it was 6 chang long, the tail was not forked and was pointing northwards, at K'ang Ch'i-tu [around Vir]; on the 4th cyclical day it was moving towards the northwest, pointing eastwards; on the 6tb cyclical day it was 8 chang long, at Chang. On the 20th cyclical day, it was 3 ch'ih long, and not visible at the right of Hsuan-yiian [around Leo, and LMi, including Regulus]. A "sweeping star," in most cases, points towards the west when it rises at dawn, and points towards the east when it rises at dusk. No "sweeping star" points towards all directions, offending notoriously as in this case. As stated above, on the 21st. cyclical day a "guest star" appears beneath Tung-ching, and on the 34th cyclical day, 8th month, a "sweeping star" appears at Wei. We can therefore conclude that these three "novae" and the twice-mentioned comet are all a single phenomenon—Halley's Comet, the path of which is shown in figure 1. The date of perihelion of Halley's Comet in this year, A. D. 837, would be about March 1. The nova on January 26 A. D. 962. It is stated in Sung-shih: On the 46th cyclical day, 12th month, 2d year of Chien-lung of the Sung dynasty, a "guest star" appears at the east of T'ien-shih Huan-tsung Je'n-hsing [the area between Lyr and Boo, Dra and Ser] with a slight flame. On the 8th cyclical day, 2d month, it disappears at Ch'i-hsing [Great Dipper: a, 0, y, S, e, f, 17 UMa]. This object was obviously a comet. We shall now correct the mistakes in Lund- mark's catalog, and add the new material we have collected to make this new catalog of 90 ancient novae up to A. D. 1700, presented in table 3. There are probably 11 supernovae (Nos. 17, 27, 30, 45, 57, 60, 67, 68, 70, 82, and 85) in this catalog. Within the past 1000 years there have been 7 supernovae: A. D. 1006, Lupus A. D. 1181, Cassiopeia A. D. 1230, Hercules A. D. 1604, Ophiuchus A. D. 1054, Taurus A. D. 1203, Scorpio A. D. 1572, Cassiopeia This material indicates that the frequency of the occurrence of supernovae within the Milky Way system is greater than the previously ac- cepted estimate and that a new supernova ap- pears every 150 years.

Abstract

Previous lists of ancient novae recorded in Chinese history have been revised and augmented to form a new catalog of 90 novae, some of which may be radio point sources. The frequency of supernovae is found to be greater than previous estimates, and novae are found to be noticeably concentrated in galactic latitude towards the galactic plane.

From these and other sources (given indicated by its old name. Each date is also in table 3) we have compiled a list of ancient given according to the Julian calendar before showers.
