Description
The aim of the present work is the detection of solar g-modes, making
use of their spatial and temporal properties, by means of a new
observational strategy. The basic data, gathered at the Observatorio del
Teide in 1993, consists on daily solar velocity measurements taken
continuous and sequentially at six different and symmetric positions on
the solar disk. By correlating the time series resulting of the
reduction process, from different positions and considering the
geometrical properties of different modes (l,m) on the Sun's surface,
some of them can selectively be eliminated of enhanced. Moreover the
main spectral features present in the resulting power spectra must have
precise phase relations if they correspond to global solar g-modes. The
severe constraints that the above properties established, have been
applied to the best observational obtained series (summer 1993). As a
result, a discrete series of peaks have been selected that fulfill all
the imposed conditions, and therefore they can be interpreted as being
of solar origin.
