Abstract
AbstractWe report the measurement of the acoustic locations of layers of sharp variation in sound speed in the interiors of 19 solar‐type stars observed by the Kepler mission. The oscillatory signal in the frequencies arising due to the acoustic glitches at the base of the convection zone and the second helium ionisation zone was utilised to determine their location by four independent methods. Despite the significantly different methods of analysis, remarkable agreement was found between the results of these four methods. Further, the extracted locations of these layers were found to be consistent with representative models of the stars (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
