DESCRIPTION:Speakers: Christopher Middleton (University of Johannesburg)\n
 Studying pulsating stars in Eclipsing binaries has the potential to be an 
 exacting test of theoretical stellar models as a result of the large numbe
 r of constraints physically that can be imposed on individual components i
 n the binary system. In this particular example\,  Kpl Rumple\, the measur
 ement of the large number of frequencies in the star of precisely known ma
 ss and radius from binary modelling will enable the identification of puls
 ation modes. This is vital as a proper physical understanding of δ Scuti 
 pulsations will ensue. It also holds the promise of direct detection of th
 e spatial distribution of pulsations on stellar surfaces.\n\nAsteroseismol
 ogy is the ultimate goal: the derivation of internal rotational behaviour 
 in stars\, accurate determination of stellar aging with associated metalli
 cities and the determination of the amount of convective core overshooting
  in stellar interiors.\n\nThe research involves the analysis of data obtai
 ned through membership of the Kepler Asteroseismic Consortium Working Grou
 p 9\, analysing proprietary data received from the Kepler Space Telescope.
  \n\nThe data are de-trended\, and subject to refined sophisticated analys
 is routines using many software platforms based on sound physical principl
 es in the determination of the binary parameters and pulsating frequencies
  of the pair. \n\nAnticipated conclusions that might be derived from the c
 onclusion of this project are discussed.\n\nhttps://events.saip.org.za/eve
