Temperature and brightness variations on Betelgeuse

Temperature and brightness variations on Betelgeuse

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.
