Abstract:
We discuss a collection of archival multi-colour photometric data of
the variable WC9-type Wolf-Rayet star WR103=HD164270 observed over a
time interval of eleven years. The photometric systems used are
Walraven VBLUW, Bessel UBV and Stromgren uvby. The purpose is to
search for periodicity and to disentangle continuum and line emission
variations.
Description:
Multi-color photometric data of the variable WC9-type Wolf-Rayet Star
WR 103 = HD 164270 made in a time interval of eleven years. The
photometric systems used are Walraven VBLUW, Bessel UBV and Stroemgren
uvby.
