CCD PHOTOMETRY OF THE DELTA-SCUTI STAR KAPPA(2) BOOTIS

CCD time-series differential photometry of the binary star kappa Boo h as been carried out from a small in town situated telescope. One compo nent of the system is known to be a delta-Scuti pulsator. Due to the h igh S/N data, four frequencies have been detected even though the wind ow function is quite complicated. A search for a standard model that f its all available data, including the observed mode frequencies, produ ces a model, which fits everything well, but with an unlikely combinat ion of modes. This demonstrates the necessity of redundant data of ver y high quality, if the seismic studies shall lead to progress in the u nderstanding of stellar evolution. An interesting byproduct is that th e analysis leads to precise prediction for observables that we expect to have in the near future, such as the distance to be published in th e Hipparcos catalog.
