D.C. SCIENTISTS' INSTRUMENT CONTRIBUTES TO MEASUREMENT OF HEAT FROM 3 STARS
Pasadena, California (JFK+50) On August 21, 1922, the Evening Star reports "the heat of three stars has been measured by" Dr. C.G. Abbot and L.B. Aldrich, officials of the Smithsonian Institution "visiting the Carnegie Solar Observatory*" on Mt. Wilson.
The heat from Aldebaran, Capella and Betelgeuze was gathered by a giant 100 inch telescope** and "finally brought into a finer focus by the instrument of the Washington scientists."
The heat was calculated at 10,000 degrees centigrade***.
*Carnegie Solar Observatory (Mt. Wilson Observatory) is located in Los Angeles County on Mt. Wilson, a 1740 meter peak in the San Gabriel Mountains.
**The 100 inch Hooker telescope was completed in 1917 & was the largest in the world until 1949.
***10,000 degrees C. equals 18,032 degrees F.
