Kappa Coronae Borealis b

Kappa Coronae Borealis b 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 Kappa Coronae Borealis b rather than just read about it. In short: Kappa Coronae Borealis b is an extrasolar planet approximately 98 light-years away in the constellation of Corona Borealis. This planet was discovered by Johnson et al., who used the radial velocity method to detect wobbling of the star caused by a planet move around by its tug of gravity.

Key takeaways

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

Reference excerpt

Kappa Coronae Borealis b is an extrasolar planet approximately 98 light-years away in the constellation of Corona Borealis. This planet was discovered by Johnson et al., who used the radial velocity method to detect wobbling of the star caused by a planet move around by its tug of gravity. It was first discovered in September 2007 and was published in November. The planet is 1.8 Jupiter masses, or 570 Earth masses, although only the minimum mass is known since the inclination is not known. It orbits at a distance of 2.7 astronomical units, or 400 gigameters, and takes 1,208 days, or 3.307 years, to orbit around Kappa Coronae Borealis.

Worked examples

Example 1 — a first encounter with Kappa Coronae Borealis b

Start with the simplest possible case. Write down what Kappa Coronae Borealis b 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 Kappa Coronae Borealis b 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 Kappa Coronae Borealis b 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 Kappa Coronae Borealis b

In research
Kappa Coronae Borealis b 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 Kappa Coronae Borealis b 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
Kappa Coronae Borealis b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Corona Borealis, Exoplanet stubs, Exoplanets detected by radial velocity, so understanding it makes those chapters shorter.
In everyday life
Look for Kappa Coronae Borealis b 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.
