摘要
The Large Synoptic Survey Telescope (LSST) is projected to begin full science operations in 2023. It will photometrically observe roughly 13 million white dwarfs in the southern sky to a single-visit depth of r = 24.5, obtaining parallax, proper motion, and 6-filter color measurements. Perhaps most excitingly, LSST will revisit every field 1000 times over its 10-year operation, holding massive potential for variable white dwarf science. We highlight the beginning steps in our work to test LSST's sensitivity to constrain various aspects of pulsations throughout the multi-parameter color-space of every white dwarf instability regime. We anticipate detecting variability in tens of thousands of white dwarf pulsators through the survey lifetime.
