The Menkalinan spectrum is characteristic of a white A2IV subgiant star.
Menkalinan is actually a multiple star system. According to Burnham the A and B components are almost identical in size and spectrum and revolve with a period of 3.96 days. The orbit appears almost edge-on to the earth. So one of the two stars eclipses the other twice each revolution.
During an eclipse, about 25% of the diameter of one star is covered by the other, and
the brightness of the pair of stars decreases by about 0.09 magnitudes.
According to Burnham, the diameter of each star is about 2.6 times that of the sun. One star is about 2.35 times as massive as the sun, while the other star contains about 2.25 solar masses.
There is a third component to the system, Menkalinan C, of Apparent Magnitude 14.1. The C component is separated from A and B by 13 sec of arc which corresponds to a projected distance of 330 AU or more than 8 times the radius of the solar system out to Pluto.
