13. Fields of activities Photometric characterization of seismo targets Photometric characterization of seismo targets Time series photometry of exofields Time series photometry of exofields Guide for subfield selection: ROTSE-I Guide for subfield selection: ROTSE-I Successful applications: Successful applications: - Low amplitude variation of classical - Low amplitude variation of classical pulsating stars (GI Zoltán Kolláth) pulsating stars (GI Zoltán Kolláth) - Blazhko and double mode RR Lyrae stars - Blazhko and double mode RR Lyrae stars (headed by Merieme Chadid, France) (headed by Merieme Chadid, France)

14. Pulsating stars studied by COROT Radial region: long periods – exofields Radial region: long periods – exofields Non-radial region: main sequence – shorter periods Non-radial region: main sequence – shorter periods Joergen Christensen Dalsgaard

15. Simplest waves Made by Zoltán Kolláth

16. Targets of asteroseismology: existing oscillations amplified by 100000 (David B. Guenther)

17. Propogation of waves with different parameters White – l = 0 White – l = 0 Blue – l = 2 Blue – l = 2 Green – l = 20 Green – l = 20 Yellow – l = 25 Yellow – l = 25 Red – l = 75 Red – l = 75 Joergen Christensen-Dalsgaard

18. Method of inversion – asteroseismology Differential layer between Green and Yellow waves is investigated Many waves – many layers are studied Joergen Christensen-Dalsgaard

19. Data obtained for Theta Tucanae 6 weeks, three sites – single site 20 years earlier

20. First step of inversion finding the frequencies of waves 10 waves were identified 10 waves were identified Binary nature was discovered Binary nature was discovered Spectroscopically confirmed later Spectroscopically confirmed later
