C- and X-type Asteroids in the Hungarian Group

Transactions of IAA RAS, issue 51, 49–57 (2019)

Keywords: celestial mechanics, asteroids, taxonomical types, asteroid families

Abstract

The taxonomy of asteroids in the Hungarian group was analysed. Earlier, two families of asteroids were identified in this area: (434) Hungaria and (1019) Strakea. The latter family is formed by S-, L-type asteroids, which is no doubt, since suchlike asteroids predominate in the inner regions of the asteroid belt. As for the family (434) Hungaria, it was found to consist of C-, X-type asteroids. As is known C-type asteroids predominate in the outer regions of the asteroid belt. The presence of a large number of such asteroids in this family required a special study. As a result of the albedo analysis, it was found that asteroids of C- and X-types in (434) Hungaria are characterized by а high albedo. This led to the conclusion that C-type asteroids were previously classified erroneously. In fact, C-type asteroids, as well as X-type ones, should be assigned to type E in the Hungarian family.
