Reference excerpt

This is a List of exoplanets discovered between 2000–2009. For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information)

Former candidates The companion to HD 131664 (discovered in 2008) has been shown to have a true mass much greater than its minimum mass, and is thus a low-mass star rather than a planet. Similarly, a 2017 study showed 2MASS J21402931+1625183 b to actually have a mass of 69+8−9 MJ, making it a high-mass brown dwarf or a low-mass red dwarf.

Worked examples

Example 1 — a first encounter with List of exoplanets discovered between 2000–2009

Start with the simplest possible case. Write down what List of exoplanets discovered between 2000–2009 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 discovered between 2000–2009 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 discovered between 2000–2009 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 discovered between 2000–2009

In research: List of exoplanets discovered between 2000–2009 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 discovered between 2000–2009 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 discovered between 2000–2009 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s-related lists, Lists of exoplanets by year of discovery, so understanding it makes those chapters shorter.
In everyday life: Look for List of exoplanets discovered between 2000–2009 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.
