WDEe Angle Telescope Transit Search (WATTS): A Low-Elevation Component of the TrES Network

摘要

The WDEe Angle Telescope Transit Search (WATTS) is a low-elevation small aperture, wDEe-field (5.5 degrees x 5.5 degrees), transit search instrument capable of achieving the photometric precision needed to detect giant extrasolar planets. The system is designed to simultaneously observe tens of thousands of stars with R magnitudes between 10 and 13. In just over one year of operation, WATTS has completed five observing campaigns. During this period, 20 candDEates have been DEentified from WATTS data. As the fourth component of the TrES network, WATTS significantly increases the efficiency of the survey when data are combined.
