| Abstract: |
The Large Synoptic Survey Telescope (LSST) is currently by far the most ambitious proposed ground-based optical survey. With initial funding from the US National Science Foundation, Department of Energy laboratories and private sponsors, the design and development efforts are well underway at many institutions, including top universities and leading national laboratories. The main science themes that drive the LSST system design are Dark Energy and Matter, Solar System Inventory, Transient Optical Sky, and Milky Way Mapping. The LSST system, with its 8.4-m telescope and 3,200 Megapixel camera, will be sited at Cerro Pachon in northern Chile, with first light scheduled for 2013. In a continuous observing campaign, LSST will cover the entire available sky every three nights in two photometric bands to a depth of V ≈ 25 per visit (using two 15-second exposures), with exquisitely accurate astrometry and photometry. During the proposed survey lifetime of 10 years, each sky location would be observed about 1000 times, with the total exposure time of 8 hours distributed over six broad photometric bandpasses (ugrizY). I describe how these data will impact AGB star research and speculate how the system could be further optimized by utilizing narrow-band TiO and CN filters. |
