Dr. Joel Hartman (Princeton University)

In this talk I will present the HATPI instrument, a new facility at Las Campanas Observatory that uses 64 wide-angle, 9.6 cm diameter lenses and large-format back-illuminated CCDs, to observe the full night sky above approximately 35 degree altitude at a cadence of 45 s and a spatial scale of 19.7" per pixel. I will describe the instrument and data processing pipeline, and the data products that are being made publicly available. I will also highlight some of the science topics being addressed with this facility, including searching for long-period transiting giant planets (i.e., Jupiter analogs), finding small, fast-moving asteroids as they pass (or impact) the Earth, and studying bright, rapidly evolving transient events.
