A spectroscopic search for oscillations in the 769.9 nm potassium line of Procyon
Published online by Cambridge University Press: 03 August 2017
Abstract
A double magneto optical filter attached to the Cassegrain focus of the 1.9 m reflector of the South African Astronomical Observatory was used to observe Procyon in the 769.9 nm line of potassium during all clear hours of six nights. Velocity calibration was provided by the rotational and orbital velocity changes of the observer as well as by a continuous magnetic modulation.
