Abstract | We present an analysis of solar-like oscillations in terms of inner and outer phase shifts and apply this to the CoRoT star HD49933. Since modes of degree L=1 have lower estimated errors than modes of degree L=0 and 2, we consider what information on the location of the location of the base of an outer convective zone and HeII ionisation layer can be extracted using only modes of degree L=1.
