Scientific paper

In a search for faint, high proper motion stars, a very cold (TBB = 3500±100K) degenerate star with a featureless spectra has been found. Its proper motion is μ = 2.128±0.008 arcsec yr-1, and its apparent visual magnitude is mv = 17.2±0.1. Available data suggest that ER 8 is a possible member of the Hyades Supercluster implying a distance d ≤ 4.5 pc, a luminosity L ≤ 5.9×10-6L_sun;, and an age less than 109yr.
