In this article, we will explore the topic of Trans-Atlantic Exoplanet Survey in depth, addressing its most relevant and current aspects. From its origins to its impact on today's society, through the different approaches and perspectives that have developed over time. This topic is of utmost importance today, since it has generated extensive debate and reflection in various areas, from politics to culture, and has marked a turning point in the way we address different problems. Throughout the development of this article, we will analyze the different aspects of Trans-Atlantic Exoplanet Survey, delving into its implications and generating a space for critical reflection around this phenomenon.
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.[1]
The TrES survey is no longer operational.
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.
