The spectra of the smallest examples of these bodies indicate enrichment in iron hydride and calcium titanate, and as they decrease in size, chromium and vanadium monoxide increase in abundance, lending credence to their birth following the destruction of population III stars.

The spectra of the smallest examples of these bodies indicate enrichment in iron hydride and calcium titanate, and as they decrease in size, chromium and vanadium monoxide increase in abundance, lending credence to their birth following the destruction of population III stars. Because they are typically less than one third of a solar diameter, they may not initiate helium fusion, and thus may have lifespans that reach into the trillions of years. The most likely hosts for terrestrial exoplanets, they include the K and L spectral classes.  FTP, name this stellar class which comprises nearly 70 percent of the stars in the universe, whose nearest example is Proxima Centauri.
