Trans-Atlantic Exoplanet Survey

Trans-Atlantic Exoplanet Survey is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Trans-Atlantic Exoplanet Survey rather than just read about it. In short: 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.

Key takeaways

Trans-Atlantic Exoplanet Survey belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Trans-Atlantic Exoplanet Survey to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Trans-Atlantic Exoplanet Survey from memory before moving on to harder problems.

Reference excerpt

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.

Worked examples

Example 1 — a first encounter with Trans-Atlantic Exoplanet Survey

Start with the simplest possible case. Write down what Trans-Atlantic Exoplanet Survey claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Trans-Atlantic Exoplanet Survey before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Trans-Atlantic Exoplanet Survey ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Trans-Atlantic Exoplanet Survey

In research: Trans-Atlantic Exoplanet Survey appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Trans-Atlantic Exoplanet Survey in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Trans-Atlantic Exoplanet Survey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical observatories in Spain, Astronomical observatories in the United States, Exoplanet search projects by small telescope, so understanding it makes those chapters shorter.
In everyday life: Look for Trans-Atlantic Exoplanet Survey outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
