Scientific paper

IRAS has detected about 70 percent of the 66 F, G, K nearby dwarf stars investigated here. The sample included chromospherically active as well as nonactive dwarfs. The detected stars show emission at 12 and 25 microns. Their 12 micron luminosity is in the range 1 - 13 x 10 to the 30th erg/s and it is strongly correlated to the star's total luminosity. There are indications that some of the stars possess IR emission in excess of that expected from a stellar photosphere.
