Scientific paper

Photoelectric spectrometry, used at the Cambridge and Palomar observatories for determining stellar radial velocities, has an accuracy of 1 km/s (200 inch telescope) for magnitude 14 stars, and 0.3 km/s for magnitude 11. Palomar's stationary spectrometer mask contains 341 slots in a 600 angstrom band, and the spectrum is swept over it four times per second by a plane-parallel fused-silica plate, while the mask of the CORAVEL instrument at Geneva Observatory passes 1,500 lines covering a 1,700 angstrom range from ultraviolet to green. Along with speckle interferometry, this procedure is being applied to the visual binary 1 Geminorum (magnitude difference 0.3, separation 0.21 seconds of arc), whereby a synthesis of the spectroscopic and visual orbits will permit a calculation of the individual stars' absolute masses.
