- Originally thought to be possibly due to the presence of an Earth-like planet, it is now accepted that the irregularities are due to a large starspot.
- There is evidence of large areas of starspot coverage, and they have intense and variable X-ray and radio emissions ( approximately 1000 times that of the Sun ).
