Solar analogs in open clusters at different ages:
By monitoring the Solar-like stars in open clusters (which have diameters of ~1 degree) at H & K, for example, one can sample the variability extremes that Sun-like stars may undergo without having to wait hundreds or thousands of years for the Sun to experience a similar episode. Since clusters span a range of ages, one can seek a correlation between the degree of the excursions and the stellar age. At the moderate resolution required (R ~ 5,000), the multiplexing advantage and wide-field of this telescope are essential. About a dozen clusters should be observed down to 18th mag.
