Abstract: |
We review the work of our group, and others, on the photometric variability of red giants, and describe some new results from merged AAVSO and robotic telescope photometry of 13 stars, and from VRI photometry of 34 stars. Topics include: periods and amplitudes; pulsation modes; multiperiodic pulsation; long-term and very-long-term variability; wavelength dependence of amplitude; amplitude variability; period variability; and red supergiant variability. This work has benefitted from the contributions of skilled amateur astronomers, and of undergraduate and high school research students. |
