Descripción
The GOLF team pushes a new concept of instrument devoted to the search
of gravity modes and low order low frequency p modes in order to improve
our knowledge of the deep solar interior. The instrumental concept is to
measure the Doppler shift together with the time evolution of the D1
sodium line using a 15 point resonance spectrometer. A sodium vapor
resonance cell placed in a static magnetic field varying along the
longitudinal axis is used to sample simultaneously 8 points on each wing
of the line. New Active Pixel Sensor detectors will be specifically
designed for this instrument. A low spatial resolution of the Sun is
also under study in this concept. First ground-based observations with
this instrument are scheduled for 2001/2002 at Tenerife. The space
concept of this instrument is under study in France as an R&T
(Research and Technology) study sponsored by CNES, the French Space
Agency. After some determining validation tests, this kind of instrument
might be placed onboard either a micro satellite or a satellite
dedicated to the study of the Sun.
