The F-typeprimarystar is a variable of the BY Draconis type, rotating rapidly on its axis over a period of 3.5 days (some seven times more rapidly than the Sun). Its variability is caused by patterning on the chromosphere of the star itself, and so the star'sbrightness changes as it rotates. The effect is not perfectly periodic, but increases in brightness are seen over periods of three to four days, approximately matching the star's rotation period.
The motion of 111 Tauri through the Galaxy suggests that it belongs to the Hyades Moving Group, sharing an origin in the distant past with the Hyadescluster that forms the 'face' of Taurus the Bull, though it now lies some way from the main cluster in the sky. It is also rather closer to the Sun than most the stars in the Hyades, at a distance of some 48 light years.
