A new survey of variability in the core of M15 with TRIFFID-2
Abstract
A two-week campaign of high-resolution imaging of the centre of M15 using the tip/tilt correcting TRIFFID-2 camera, followed by analysis with ISIS (image matching & subtraction software), has produced the most sensitive survey to date of variable stars in the central ~1x1 arcmin2 - a total of 48 were detected -, and constrains the size of the dwarf nova population.
