As a subgiant, the star has entered the post-main-sequence phase of evolution having exhausted core hydrogen and transitioned to the hydrogen - shell - burning phase around a helium - rich core, evolving toward the red giant branch (di Mauro et al, 2003). (solstation.com)
This stage of core helium burning, however, lasts only about a hundredth of the time taken for core hydrogen burning. (britannica.com)
It rotates more slowly than Sol with a period at 34 days (Baliunas et al, 1996) and appears to be further along in core hydrogen - fusion, with a relatively weak 11 - year cycle of star spots and related chromospheric activity. (members.nova.org)
