TITLE: --D-i`i-tribution of th-e---if~ments of Orbits in the Eruption Theory. (Raqredeleniye elementov orbit v teorii izverzheniya). PERIODICAL: Astronomicheskiy Zhurnal, 1957, Vol.34, No.4. PP-568-580 (USSR). ABSTRACT: Vsekhsvyatskiy (Refs. 3 and 4) has shown that the eruption theory can explain orbital characteristics of short-period and periodic comets. Duklmovskii (Ref-5) has argued against these conclusions but his results are inadmissible because of elementary mistakes. Dukhnovskii maintains that Soviet Astronomers have only worked out the plane problem while already in 1934 Vsekhsvyatskiy had worked out the spatial case and obtained results which clearly supported the eruption theory. The alm of the present work is to establish the theoretical distribution of elements of orbits of short lj~riod comets on the basis of eruption theory. The following-problem is taken up-. to find the distribution of elements of orbits of the eruption products which, on the boundary of the sphere of influence of Jupiter, Card 1/3 have a uniform distribution of directions and magnitudes 3-3-4-6/19 Distribution of the Elements of Orbits in the Eruption WneOXY- of relative vi~]_ocities, if the latter lie within certain limits. The upper limit is taken as 8.5 km/sec and the lower as zero. The contra of the distribution of the relative velocities is taken to be coincident with the centre of the planet, i.e. the linear dimensions of the sphere of influence are assumed to be small -compared with planet - sun distance. The planet is assumed to move in a circle and the attraction due to the planet is neglected beyond the boundary of the sphere of influence. These simplifications should not lead to any essential errors. A theoretical expression for the above distribution is obtained and is in good agreement with observations. A comparison of the theoretical and observed distributions indicates that during the last two centuries short period comets were formed as a result of eruption processes in Jupiter's system. The value of the relative velocity did not in the mean, exceed H = 0.23 (i.e. 6.9 km/sec5. This corresponds to a maxirmim possible velocity on the surface of the satellites of the Card 2/3 order of 7-9 km/sec. 33-4-6/19 Distribution of the Elements of Orbits in the Eruption Theory. Using the known number of short period comets in the Jupiter family (65 comets) the total number of cometary objects thrown out from that family may be estimated. This is of the order of 600-800.- It was found that the number of short-period comets as a f)6n .�tion of the perihelion distance is proportional to q * , and increases rapidly towards Jupiter's orbit for r>, A.U. It is shown that Dubyago's hypothesis (Ref.9) of condensation of short period comets in -the zone of motion of Jupiter is inconsistent and erroneous. There are 7 figures, 7 tables, and 9 references, 7 of which are Slavic. SUBMITTED: September 17, 1956. ASSOCIATION: Department of Astronomy of the Kiev State University.

Ed.: Samsonenko., L.V.; abch. Ed.: Akhlamov, S.N. PURPOSE: This book is intended for astronomers, students, and graduate students in astronomy. It can also be useful to others interested in comets, their observation, and the history of astronomy. COVERAGE: The book contains data on the nature of comets, their origin and evolution., and a catalog of every comet ever known. The main part of the book is devoted to a detailed description of the physical characteristics of comets and the circumstances under which they were discovered. The book also covers photometric study of comets and the results of a statistical study of the absolute magnitude of comets. The last part of the book on the obser- vation of comets is not a complete study, nor was it intended to be such. Re- cognition for help in compiling the book is given to the author's wife, E. I. Vsekhsvyatskaya, and to T. A. Vodoplyanovaya, G. M. Nikollskiy, and S. A. Glebcva Card 113 Physical Characteristics of Comets 666 of the Department of Astronomy, Kiev University. There are 155 references for Parts I and 11, 89 Soviet, 31 English, 25 German, 7 French, 2 Dutch, 1 Italian. Six Soviet sources and 114 non-Russian language sources were used in the com- pilation of Part III. In this section, by far the main part of the book, the source material is listed after each entry of the individual comet Ix-ing studied. TABLE OF CONTENTS: Foreword PART I.

The observations were conducted in Moscow, Kiyev and Crimea (Crimean Astrophysical Observator-J) from Januury 23~to June-4, 1957. The maximum luminosity of dn took place on April 25, and by the end of June the luminosity decreased down to 7M8. S. V.

Field glasses (50 mm x 7) and a 70-mm tube were usef for estimating its luminosity. Its stellar magnitude varied from 2TO (on August 7) to 5T2 (on Septem ber 14). The tail length and the color of the comotar~j head were noted. During the first days the nucleus was bright-yellow, the tail and the head were of a.red- dish shade; the parabolic outline of the head was well visible, On August 9, with magnification 100, elongation of the nucleus in direction perpendicular to the tail axis was noticed.
