Descripción
From the analysis of radial velocity measurements of the Sun, obtained
at Izaña from 1976 to 1985, stable periods longer than 1 day,
have been found in the observed signal. The appearance of an oscillation
with a 13 day period has been confirmed. The comparison, for 1981 - 84,
of the observations with a calibrated numerical model of the passage of
inhomogeneities (spots and plages) on the solar surface, shows that the
signal is not only due to this effect. It is believed that a velocity
field, probably related to the surface inhomogeneities, contributes to
the observed signal.
