A search has been made among the faint stars with large proper motion found on the Palomar Survey plates for objects that, statistically—judging from their magnitude, color, and proper motion—would appear to be fainter than one ten-thousandth of the sun's luminosity. A total of 122 such objects have been found, and an analysis made for solar motion among them does, indeed, indicate that they must be of exceedingly low luminosity.
Keywords: degenerate stars, subdwarfs
