List of exoplanets detected by timing

List of exoplanets detected by timing 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 List of exoplanets detected by timing rather than just read about it. In short: This is the list of 20 extrasolar planets that were detected by timing –– 8 by pulsar timing and 12 by variable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets.

Key takeaways

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

Reference excerpt

This is the list of 20 extrasolar planets that were detected by timing –– 8 by pulsar timing and 12 by variable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets. The same general mechanism is used for variable stars, although usually in visible light rather than radio.

Planets The most massive planet detected by timing is HW Virginis b, which masses 19.2 MJ; the least massive planet is PSR B1257+12 b, which masses 0.00007 MJ or 0.022 M🜨. The longest period of any planets detected by timing is PSR B1620-26 b, which is 36525 days or 100 years; the shortest period is SDSS J1228+1040 b, which is 0.0857 days. There are 9 members of multi-planet systems, including three orbiting around PSR B1257+12.

Worked examples

Example 1 — a first encounter with List of exoplanets detected by timing

Start with the simplest possible case. Write down what List of exoplanets detected by timing 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 List of exoplanets detected by timing 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 List of exoplanets detected by timing 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 List of exoplanets detected by timing

In research: List of exoplanets detected by timing 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 List of exoplanets detected by timing 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: List of exoplanets detected by timing is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets detected by timing, Lists of exoplanets, so understanding it makes those chapters shorter.
In everyday life: Look for List of exoplanets detected by timing 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.
