Physics of the solar twin: the example of 18 Sco

M. Bazot

Abstract.
Solar twins are nowadays a growing center of interest. They are defined as being spectroscopically identical to the Sun. There is actually an on-going race between spectroscopic surveys to find the "best" solar twin. However, the progresses in high-precision in spectroscopy and interferometry also allows us to study the seismic characteristics of some solar twins and to measure their radiuses. I present in this talk the results obtained for the brightest of them all: 18 Sco.
