Abstract

The rotation period of the Ap star HDE 318107 has been determined from magnetic and photometric observations obtained between August 1992 and September 1998.

Key words: stars: chemically peculiar stars: individual: HDE 318107 stars: rotation

* Based on observations collected at the European Southern Observatory, La Silla, Chile (ESO programmes Nos. 49.7-030, 50.7-067, 51.7-041, 52.7-063, 53.7-028, 55.E-0751, 58.E-0159, and 61.E-0711, and at the Geneva Observatory photometric telescope, La Silla)
