Dubyago A.D. Orbits Determination. In Russian/Dubyago A.D. Opredelenie orbit.

Dubyago A.D. Orbits Determination. In Russian/Dubyago A.D. Opredelenie orbit. Alexander Dmitrievich was a virtuoso computational scientist. He calculated a parabolic or elliptical orbit for 2-3 hours using three observations. Since the creation of the Astronomical Circular in Kazan by D.I. Martynov, Alexander Dmitrievich has calculated the first elements and search ephemerides for almost all newly discovered comets. Alexander Dmitrievich described his extensive experience in celestial and mechanical computation in the monograph entitled Defining Orbits, published in 1949. Alexander Dmitrievich was not a specialist in a narrow field of knowledge, his theoretical research and observation covered not only comet astronomy, but other fields.
