Definition of a Parabolic Orbit: the Search for a Solution with Algebraic Equations

Autor: V. B. Kuznetsov

Publikováno v: Solar System Research. 55:358-366

An algorithm is proposed for finding a solution for determining a preliminary parabolic orbit, using the method proposed by the author, based on solving a system of algebraic equations for two dimensionless variables. The solutions of the system are

Revisiting the Determination of a Preliminary Orbit for a Celestial Body

Autor: V. B. Kuznetsov

Publikováno v: Solar System Research. 53:462-472

This paper revisits the classical problem of determining a preliminary orbit of a celestial body from angular observations. It is proposed to solve this problem using a universal method based on the Gaussian equation in the Shefer form. The resulting

Parabolic orbit determination. Comparison of the Olbers method and algebraic equations

Autor: V. B. Kuznetsov

Publikováno v: Solar System Research. 50:211-219

In this paper, the Olbers method for the preliminary parabolic orbit determination (in the Lagrange–Subbotin modification) and the method based on systems of algebraic equations for two or three variables proposed by the author are compared. The ma

Determination of the parabolic orbit for a body moving in the plane of the ecliptic, by the Laplace method

Autor: V. B. Kuznetsov

Publikováno v: Solar System Research. 46:136-143

A modification of the Laplace method for the determination of a preliminary orbit of a body moving in the plane of the ecliptic is presented. It is shown that on the basis of three close positions on the celestial sphere, the parabolic orbit can be d

Catalytic syntheses of poly cyclic compounds based on norbornadiene-2,5 in the presence of nickel complexes: III. Cyclic dimerization of norbornadiene-2,5 in the presence of organophosphorus additives

Autor: V. R. Flid, V. B. Kuznetsov, A. P. Belov, A. A. Grigor’ev

Publikováno v: Kinetics and Catalysis. 41:604-611

The cyclodimerization of norbornadiene-2,5 (NBD) catalyzed by the systems formed on the basis of bis(ηy3-allyl)nickel and organophosphorus compounds and the process kinetics are studied. The formation rate of all products follows the overall second-

Main stages of unusual allyl coupling involving nickel bis-η3-allyl complexes in the presence of dichlorobutenes

Autor: V. B. Kuznetsov, A. V. Shirobokov, E. G. Tyunin, V. R. Flid

Publikováno v: Kinetics and Catalysis. 41:42-47

The reactions of nickel bis-η3-allyl complexes with dichlorobutenes were studied. The overall process includes several stages, each characterized by substantially different reactions: traditional allyl coupling, substrate insertion between recombini
