Stellar Oscillations Network Group

TL;DR

The Stellar Oscillations Network Group (SONG) aims to create a global network of 1-meter telescopes equipped with high-resolution spectrographs for precise asteroseismology and exoplanet detection, focusing on bright stars.

Contribution

This paper introduces the design and goals of the SONG project, detailing its instrumentation, operational modes, and expected scientific performance.

Findings

Network will consist of 8 identical telescopes.

Designed for high-precision radial velocity measurements.

Focus on bright stars (V<6) for asteroseismology and planet hunting.

Abstract

Stellar Oscillations Network Group (SONG) is an initiative aimed at designing and building a network of 1m-class telescopes dedicated to asteroseismology and planet hunting. SONG will have 8 identical telescope nodes each equipped with a high-resolution spectrograph and an iodine cell for obtaining precision radial velocities and a CCD camera for guiding and imaging purposes. The main asteroseismology targets for the network are the brightest (V<6) stars. In order to improve performance and reduce maintenance costs the instrumentation will only have very few modes of operation. In this contribution we describe the motivations for establishing a network, the basic outline of SONG and the expected performance.
