The Trans-Atlantic Exoplanet Survey, or TrES, used three 4-inch (10 cm) telescopes located at Lowell Observatory, Palomar Observatory, and Teide Observatory to locate exoplanets. It was made using the network of small, relatively inexpensive telescopes designed to look specifically for planets orbiting bright stars using the transit method. The array used 4-inch Schmidt telescopes having CCD cameras and automated search routines. The survey was created by David Charbonneau of the Center for Astrophysics, Timothy Brown of the National Center for Atmospheric Research, and Edward Dunham of Lowell Observatory. The TrES survey is no longer operational. Discoveries The TrES project discovered a total of five planets in its years of operation. All were discovered using the transit method. Note that the discovery papers do not use the "b" suffix typically used in extrasolar planet designations. While forms with and without the b are used in the literature, the table here uses the designations assigned by the discoverers.
