6 seismic solar analogs asteroseismologic data

Stellar modeling using seven independent stellar evolution codes yielded consistent masses, radii, and ages. These stars have masses between 0.91 and 1.04M_{sun}_, radii between 0.95 and 1.08R_{sun}_, and ages from about 1.8 to 9.1Gyr, with typical systematic uncertainties of +/-0.02M_{sun}_, +/-0.01R_{sun}_, and +/-0.7Gyr, respectively. One star, EPIC 206064678, exhibits properties very similar to those of the Sun, with M=1.016+/-0.033M_{sun}_, R=0.990+/-0.011R_{sun}_, and an age of 5.40+/-0.12Gyr.

It can therefore be considered a close solar twin, although it is slightly older and more metal-rich (0.25+/-0.07dex). Four targets display binarity signatures and all exhibit very low chromospheric activity. This work broadens the sample of well-characterized seismic solar analogs towards a larger sample of metallicities and ages, providing new references for comparative stellar studies and future asteroseismic investigations.
