In a 2012 Nature paper, Maehara et al. studied superflares emitted by slowly rotating examples of this type of object, finding more starspots than expected. The Subaro Telescope's HiCIAO (HI-chow) detector observed a relatively cool Jupiter-sized planet orbiting a star of this type. This type of star is relatively abundant in ionized calcium, giving rise to emission lines at 3968 and 3933 Angstroms, the H and K lines, and they have weak, but detectable, hydrogen spectral lines. This type of star, which is not the K type, has small concentrations of OH and CN radicals, but more iron, sodium, and titanium, among other metals. Examples of this type of star include 51 Pegasi, Alpha Centauri A, and Tau Ceti. For 10 points, name this fairly common type of star, prominent examples of which include the Sun.
