11. Hungarian Asteroseismology Group Established: 2005 - Participants: Margit Paparó D.Sc. – project scientist Zoltán Kolláth D.Sc. – guest investigator of CoRoT Zoltán Csubry PhD student József Benkő PhD Sódorné Bognár Zsófia PhD student – employee by HAG László Szabados D.Sc. Róbert Szabó PhD László Molnár student – employee by HAG Krisztián Sárneczky – PhD student – employed for 5 month

12. Honorary members of HAGPISTA – Piszkéstető Student’s Astronomy ELTE University • Eszter Bokor • Gyöngyi Kerekes • András Már • László Molnár • Emese Plachy • Péter Pápics • Nándor Sztankó

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

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

15. Simplest waves Made by Zoltán Kolláth

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

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

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

19. Data obtained for Theta Tucanae6 weeks, three sites – single site 20 years earlier

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

21. Photometry of seismo targets I Summer targets: 2005 2006 HD 181555 3 8 nights HD 180642 2 5 HD 170782 - 3

22. Photometry of seismo targets II • Summer targets: 2005 2006 HD 172189 2 - nights • Winter targets: HD 44195 8 3 HD 44283 4 3

23. Photometry of seismo targets III • Winter targets: 2006 • HD 50844 7 nights • Other objects HD 48434 – Gamma Dor star • V920 Aql – RR Lyrae star on the exofield

24. Time series: Schmidt telescope (90/60 cm)

26. Time series on exofield of HD 49933+ HD 49434selection on star density or well-known star in the field

27. More effective selection of subfields:ROTSE - I Posters on 8. CoRoT week: József M. Benkő and Zoltán Csubry ROTSE-I All Sky Survey as a Tool of Target Selection in the COROT Fields Zoltán Csubry, Zoltán Kolláth MUFRAN – A scriptale data processing tool for variable stars

28. New variable stars in the COROT eyes

29. Strange modes in stars COROT data will be analized here Cepheid horn: oscillations are the same as in the star Made by Zoltán Kolláth

30. I gave a large scale view of the Hungarian activity in the COROT scientific preparatory work. My colleagues will give the details and colours of this picture. HAG wish you a pleasant Hungarian COROT Day! Thank you
