Description
The VIRGO Experiment (Variability of solar IRradiance and Gravity
Oscillations) contains two types of active cavity radiometers for
monitoring of the solar constant, two three-channel Sun photometers 335,
500, and 865 nm, and a low resolution imager (LOI) with 12 pixels. The
main scientific objective is probing the solar interior by
helioseismology with p- and g-mode solar oscillations determined from
spectral irradiance (SPM) and radiance (LOI) variations on time scales
of minutes to the mission time. The measurements of the variability of
the solar constant and spectral irradiance over periods of days to the
mission time will yield information about the convection zone, as will
the comparison of the amplitudes and phases of the oscillations as
manifested in irradiance and radiance (from VIRGO) and velocity (from
GOLF and SOI).
