Pan-STARRS ―A Large Synoptic Survey Telescope Array

摘要

The IfA and collaborators are embarking on a project to develop a 4-telescope synoptic survey instrument. While somewhat smaller than the 6.5m class telescope envisaged by the decadal review in their proposal for a LSST, this facility will nonetheless be able to accomplish many of the LSST science goals. In this paper we will describe the motivation for a 'distributed aperture' approach for the LSST, the current concept for Pan-STARRS ― a pilot project for the LSST proper ― and its performance goals and science reach. We will also discuss how the facility may be expanded.
