1976 UK2. Discovered 1976 Oct. 26 by T. M. Smirnova at Nauchnyj.
Named in honor of Anatolij Mikhajlovich Cherepashchuk (1941– ), professor at Moscow State University and director of the Sternberg Astronomical Institute, respected worldwide for his work in theoretical and observational astrophysics. From an analysis of eclipses in close-binary systems he obtained correct estimates of the radii and temperatures of Wolf-Rayet stars, predicted x-ray emission in such systems, discovered optical eclipses in the unique system V1343 Aql and developed a commonly-adopted model of this object as a massive x-ray binary. He also discovered fast emission-line variability in the nuclei of Seyfert galaxies. (M 29143)
