Description
The GOLF-NG (Global Oscillations at Low Frequency New Generation)
instrument is devoted to the search for solar gravity and acoustic
modes, and also chromospheric modes from space. This instrument which is
a successor to GOLF/SOHO will contribute to improve our knowledge of the
dynamics of the solar radiative zone. It is a 15 points resonant
scattering spectrometer, working on the D1 sodium line. A ground-based
prototype is under construction to validate the difficult issues. It
will be installed at the Teide Observatory, on Tenerife in 2006 to
analyse the separation of the effects of the magnetic turbulence of the
line from the solar oscillations. We are prepared to put a space version
of this instrument including a capability of identification of the
modes, in orbit during the next decade. This instrument should be
included in the ILWS program as it offers a key to the improvement of
our knowledge of the solar core in combination with observations from
SDO and PICARD. We hope to determine the core rotation and magnetic
field, through precise measurements of oscillation mode frequency
splittings. Understanding the magnetic field of the radiative zone is
important for progress in the study of solar activity sources, an
important player for the long-term Sun Earth relationship.
