  • We analyze space- and ground-based data for the old ($7.0\pm0.3$~Gyr) solar analogs 16 Cyg A and B. The stars were observed with the Cosmic Origins UV Spectrographs on the Hubble Space Telescope (HST) on 23 October 2015 and 3 February 2016 respectively, and with the Chandra X-ray Observatory on 7 February 2016. Time-series data in \ion{Ca}{2} data are used to place the UV data in context. The UV spectra of 18 Sco (3.7$\pm0.5$ Gyr), the Sun (4.6$\pm0.04$ Gyr) and $\alpha$ Cen A ($5.4_{-0.2}^{+1… CONTINUE READING
