Photoelectric Observations of Visual Double Stars.
Abstract
Photoelectric observations of the magnitudes and colors of both components of 40 visual double stars, all of which are likely to be physical pairs, have been made with the 82-inch telescope of the McDonald Observatory. It appears that many of the brighter components must be more luminous than main-sequence stars.
