Stellar Spectrophotometry from a Pointed Rocket
Abstract
A 13-inch telescope with a three-channel photoelectric scanner was successfully flown on an Aerobee rocket. The whole rocket assembly was pointed at four program stars with an absolute accuracy exceeding 20 seconds of arc. Two photometric scans (of 20-sec duration) of each program star were made with a resolution of 10 A. The observed stars were a CMa, Al V; E CMa, B2 II, Pup, 0Sf; and T1 Vel, `vCS. The spectrum of each star is presented in absolute energy units. A preliminary discussion of the spectra is made.
