CoRoT3-KASC7 #08 - T. Bedding - Unlocking the secrets of gamma Doradus stars using echelle diagrams

Conference given during The Space photometry Revolution, CoRoT Symposium 3, Kepler KASC-7 joint meeting (6-11 Jul 2014, Toulouse, France) http://corot3-kasc7.sciencesconf.org/ Session: 1 - Probing stellar structure and evolution with asteroseismology Date: July 7, 2014 Title: Unlocking the secrets of gamma Doradus and delta Scuti stars using echelle diagrams Speaker: Tim Bedding Abstract: The echelle diagram is a powerful method for visualising oscillation spectra. It can be used to find frequency spacings of p modes, period spacings of g modes, and departures from regularity that arise from glitches in stellar interiors. It has been used with great success in visualising solar-like oscillations, from the main sequences to the red giant branch. Here we apply it to hybrid stars that show both g-mode (gamma Dor) and p-mode (delat Scuti) oscillations. We examine Kepler data and observational models in an effort to identify modes and apply asteroseismic analysis to these fascinating objects. http://corot3-kasc7.sciencesconf.org/...
