Variable Stars: Observations
Scientific paper
The red variable U Del was extensively observed by GEOS observers from
1983 to 1992. An analysis of their observations supports the existence
of a period of 1120 d. By subtracting the signal relative to this
period, a second period of about 660 d can be evidenced.
