Reference excerpt

WD 0032−317 is a low mass white dwarf star orbited by brown dwarf WD 0032−317 b.

WD 0032−317 The white dwarf WD 0032−317 is located about 1,400 light years from Earth. WD 0032−317 formed about three billion years ago when a low mass star (possibly of 1.3 solar masses) expanded into its red giant phase. The star then blew out its outer layers leaving behind the helium-rich core (which is WD 0032−317).

WD 0032−317 b The orbiting brown dwarf, WD 0032−317 b, was massive enough to survive the red giant's nova event. It is an extremely hot and very large (75-88 Jupiter masses) brown dwarf that orbits WD 0032−317. One orbit from WD 0032−317 b takes only 2.5 hours. This object is tidally locked to its star with a day side temperature of 8,000 K (7,730 °C; 13,940 °F) and a night temperature of about 2,000 K (1,730 °C; 3,140 °F) making its temperature equivalent to a planet orbiting close to a late stage B-type star. The intense ultraviolet (UV) exposure can break down the molecules in WD 0032−317's atmosphere and vaporize materials from the surface of the brown dwarf.

Worked examples

Example 1 — a first encounter with WD 0032−317

Start with the simplest possible case. Write down what WD 0032−317 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 WD 0032−317 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 WD 0032−317 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 WD 0032−317

In research: WD 0032−317 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 WD 0032−317 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: WD 0032−317 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brown dwarfs, Planetary systems with one confirmed planet, Sculptor (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for WD 0032−317 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.
