Temperature and brightness variations on Betelgeuse
Published online by Cambridge University Press: 04 August 2017
Abstract
Changes in Ti0 band strengths correlate well with the brightness changes of α Orionis, thus supporting the hypothesis of Schwarzschild that the irregular luminosity variations of red giants are due to temperature changes in a few extremely large convective elements on their surface.
