Observations of Spectroscopic Binaries with a Solid-State Detector

  • Francis Fekel (a1), Claud H. Lacy (a1) and J. Tomkin (a1)

Extract

The recent installation of a solid-state 1024-element silicon photodiode array detector (Reticon) at the coude focus of the 2.7 m McDonald Observatory reflector has greatly extended its limits of observation for binary and multiple systems which have weak and/or broad-lined components. This detector can produce extremely high signal-to-noise ratio observations and has high quantum efficiency over the wavelength region 3000-11000Å. The observational programs of three users of this device are described below.
