| Abstract: |
The results obtained in the framework of investigations of the modal content of Delta-Scuti-star light curves are presented. Observations of a variable star X Cae consisting of 1012 datapoints are discussed, with emphasis on the frequency analysis made with the least squares simultaneous fitting of sinusoids. The measurements in B color of BD -3 deg 5741 are analyzed, and it is noted that the obtained physical parameters place the star in the left side of the instability strip and among the most luminous Delta Scuti stars. The frequency analyses of 44 Tauri, HD 101158, and V974 Oph are also reported, and their light curves are defined. |
