He was professor of astronomy at the Rijksuniversiteit Utrecht , and served as director of the ''Sterrewacht Sonnenborgh'' (now the ''Sterrekundig Instituut'') of the university. In 1901 he participated in a Dutch Solar Eclipse expedition to Karang Sago , Sumatra . He was noted for his observations of Variable Star s, and published a number of papers on the subject in ''Astronomische Nachrichten'', and elsewhere, from 1917 until 1936 . He proposed naming variable stars in each Constellation using a simple numbering system beginning with V1, V2, ... and so forth. However the double-letter system starting with RR was already in widespread use. As a result, variable stars after QZ were numbered according to Nijland's system beginning with V335. Nijland Crater on the Moon was named after him. |
