SONG - Stellar Observations Network Group
Several areas of stellar observations depend critically on nearly continuous observa tions of individual objects over very extended periods. Important examples are investigations of stellar oscillations to carry out asteroseismology,and the search for extra-solar planets. To meet this requirement we are establishing the SONG network,consisting of 8 sites with a 1-meter-class telescope with a suitable geographical distribution. These will be optimized for asteroseismology based on Doppler-velocity observations and the characterization of extra-solar planets with photometry,using gravitational microlensing. Funding has been obtained towards the construction of the prototype SONG telescope which will be set up on Tenerife,with first light expected in 2011. The full network will be established in parallel with the tests of the prototype and is planned to be operational in 2014.
