The magnetic structure of sunspots and starspots
Astronomische Nachrichten, 2002The single most important quantity determining the properties of sunspots and presumably starspots is their magnetic field. First an overview of the magnetic structure of sunspots is given, some of the progress made in recent years is described and some of the unsolved questions are pointed out. Both observational and theoretical aspects are dealt with.

The 1973 RT Andromedae Starspot
Publications of the Astronomical Society of Australia, 1991AbstractAn analysis of 1973 RT Andromedae B and V light curves is presented. The results are fitted into a spot evolution sequence found in a previous study which used the same technique on different data. The new values of the system’s physical parameters are in general agreement with the earlier ones.

Starspot mapping with robotic telescopes
Astronomische Nachrichten, 2002Robotic telescopes for photometry and imaging have been around for several years. They have been very valuable to monitor light variations due to changing spot patterns on active stars. Two new spectroscopic robotic telescopes will come online in the near future, one in Tenerife and one in Arizona.
