Limits to CCD ensemble photometry precision, and prospects for asteroseismology
1992
Publications of the Astronomical Society of the Pacific
We report results of CCD ensemble, time-resolved photometry with the KPNO 2.1-m telescope yielding precision of 400 ¿¿mag per minute of integration. Previous experience on 1-m class telescopes and well-known scaling laws for the limiting noise sources indicate that current 4-m class telescopes and existing detectors, operated as a network for about five days, would allow detection of coherent (solar-like) oscillations at an amplitude of 15 ¿¿mag. We provide detailed stellar-evolution modeling
