Blue K Dwarf Stars

TNRTB Archive - Retained for reference information

In studies of young open star clusters astronomers note that the younger the cluster the bluer and more variable are the medium and small-sized stars. They determined that the blue enhancement and variability are due to large star spots and rapid rotation. The bottom line is that life is impossible on planets orbiting stars younger than a half billion years.
