   ocr: GOLE SOME RESULTS IN A NUISHELL Now, with SOHO, for the first time the frequency spectrum of sur- face velocity has been measured from space, yielding a quality of signal never reached before. GOLF results can give a detailed profile of the sound speed in the inner core of the Sun. GOLF has now detected acoustic mode trequencies of more than 100 modes extending from 1.2 mHz to 5.5 mHz. In addition, GOLF shows clear evidence of pseudo-modes' at trequencies higher than 5.5 mHz (the acoustic cut-off trequency). A tentative discovery of two candidates for internal gravity modes remains to be verif ...
