| Description: |
The GOLF-NG (Global Oscillations at Low Frequency New Generation) instrument is an instrument devoted to the space search of solar gravity and acoustic modes, and may be chromospheric modes. This instrument, successor of 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. The ground prototype is under construction to validate the hard points and will join the Teide Observatory, at Tenerife in 2006 to analyse how to separate the effects of magnetic turbulence on 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. We hope to insert this search in the ILWS program. This instrument represents in combining observations with SDO and PICARD, a key to improve our knowledge of the solar core, in determining its rotation and magnetic field, through precise mode splitting measurements. The magnetic field of the radiative zone is fundamental for progressing on the solar activity sources, a clue for the long-term solar-earth relationship. |
