Monitoring requested for dust production study in developing planetary systems
Abstract:
Huan Meng and Dr. George Rieke (University of Arizona) have requested AAVSO assistance in monitoring three bright stars with developing planetary systems. The stars have been observed with NASA's Spitzer Space Telescope to have varying levels of dust in the circumstellar disk. These varying levels are thought to be produced through collisions among the asteroid-size debris in the disk. AAVSO monitoring is requested to make certain that the variations are not caused by variability in the stars themselves and for correlation with Spitzer data being obtained.
Justification:
AAVSO monitoring is requested to ensure that the variations are not caused by variability in the stars themselves and for correlation with Spitzer data being obtained.
