Chinese SONG team
Speaker: Jianning Fu (Beijing Normal University)
2010.10.16
To install 8 1-m telescopes at 8 sites around the equator, to compose the SONG network.
To make High-precision continuous radial-velocity observations for individual stars, to study the internal structures of the target stars in detail with asteroseismological technique.
To make high time-resolution high-precision photometric observations for the stars in the bulge of the Galaxy, to search for earth-like exoplanets.
Initialized by Danish astronomers.
Distribution of the SONG telescopes
Dome of SONG telescope
1-meter telescope
Spectrograph
Primary object of SONG: 1. Asteroseismology:Long-duration high-duty-cycle high-precision radial velocity curves
2. Searching for exoplanets with the microlensing effect:
High duty-cycle moderate duration high-precision photometry for crowded star regions
Chinese SONG plan:
1. By setting up a SONG node in China, to make international collaboration and competition in the front edge field of stellar physics.
2. To build up Mini-SONG, the first Chinese global observation network located at the best sites of the world.
SCHEDULE OF CHINESE SONG PLAN
Started in May of 2009; Agreement of collaboration between China
and Denmark signed in September of 2009; Agreement of collaboration among Denmark,
China, and the USA for the network of northern hemisphere signed in December of 2009;
The third SONG workshop held in Beijing in March of 2010;
Mini-SONG project proposed2 in March of 2010.
PROGRESS
Site investigation started in January of 2010:
Site test in Delingha; Data being collected for the other
candidate sites; Composition of teams and schedule
decided in January of 2010.

A customized node of SONG:
A 1-meter universal telescope for high-precision photometry;
To make time-series observations for variable objects and lucky-imaging;
A candidate site: the South-American station of NAOC
Budget:
