(type of star with about 3/4 the mass of the Sun)
A K-type star is a star of the K-class, a
spectral class for stars of around .75 solar mass
and .75 solar radius.
They burn up their hydrogen in tens of billions of years.
They have very weak hydrogen lines.
K-type stars are a good bet for habitable extra-solar planets, but offer
few planets for study because the stars are much rarer than M-type star
and much dimmer than the hotter classes.
