Named in honor of Hans-Heinrich “Bernie” Bernstein (1953– ), senior astronomer at the Astronomisches Rechen-Institut in Heidelberg. He analyzed pulse-timing data on pulsars and was instrumental in developing an algorithm for the detection of astrometric binaries with ESA’s satellite HIPPARCOS. He detected 110 new double-star systems, together with a few brown-dwarf candidates. Bernstein is an expert in numerical mathematics, with many special applications in astrometry. (M 30800) _ _.
