WASP-28b

WASP-28b 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 WASP-28b rather than just read about it. In short: WASP-28b or K2-1b is an extrasolar planet discovered in 2010 by the Wide Angle Search for Planets (WASP) project orbiting WASP-28, a magnitude 12 star also known as 1SWASP J233427.87-013448.1, 2MASS J23342787-0134482 and K2-1. Since it orbits its star very closely, the planet is a strongly irradiated hot Jupiter.

Key takeaways

WASP-28b belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect WASP-28b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of WASP-28b from memory before moving on to harder problems.

Reference excerpt

WASP-28b or K2-1b is an extrasolar planet discovered in 2010 by the Wide Angle Search for Planets (WASP) project orbiting WASP-28, a magnitude 12 star also known as 1SWASP J233427.87-013448.1, 2MASS J23342787-0134482 and K2-1. Since it orbits its star very closely, the planet is a strongly irradiated hot Jupiter. As seen from the Earth, WASP-28b transits its host star every 3.41 days taking about 3 hours to do so. The planet was observed by the Kepler space telescope during the K2 mission engineering campaign in February 2014 as part of an early science demonstration. It was also observed from December 2016 to March 2017 during K2's campaign 12 which allowed a refinement of the system parameters.

Internal structure The planet seems to be a gas giant with a low core mass (<~10M(Earth)) and a low heavy elements content (Z<~0.2).

Worked examples

Example 1 — a first encounter with WASP-28b

Start with the simplest possible case. Write down what WASP-28b 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 WASP-28b 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 WASP-28b 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 WASP-28b

In research: WASP-28b 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 WASP-28b 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: WASP-28b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by WASP, Exoplanets discovered in 2010, Giant planets, so understanding it makes those chapters shorter.
In everyday life: Look for WASP-28b 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.
