ABELMANN, ILYA SOLOMOVITCH

ABELMANN, ILYA SOLOMOVITCH (1866–1898), Russian astronomer. Abelmann, who was born in Dvinsk, worked at several Russian observatories, mainly on the complex problems connected with the properties of meteor streams. He was concerned with the calculation of secular orbital perturbations exercised on these streams by the effects of planetary attraction. Abelmann was also well known for his efforts to spread the appreciation of astronomy, which he did through numerous popular articles. (Arthur Beer)
