HAT-P-36

HAT-P-36 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 HAT-P-36 rather than just read about it. In short: HAT-P-36, also referred to as Tuiren is a 12th magnitude G-type main-sequence star estimated to be approximately 958 light-years away from Earth in the constellation Canes Venatici. HAT-P-36 is too faint to be seen with the naked eye, but it is possible to view it with binoculars or a small telescope.

Key takeaways

HAT-P-36 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HAT-P-36 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HAT-P-36 from memory before moving on to harder problems.

Reference excerpt

HAT-P-36, also referred to as Tuiren is a 12th magnitude G-type main-sequence star estimated to be approximately 958 light-years away from Earth in the constellation Canes Venatici. HAT-P-36 is too faint to be seen with the naked eye, but it is possible to view it with binoculars or a small telescope. In 2012 a hot Jupiter-type exoplanet was discovered orbiting HAT-P-36 with an orbital period of about 1.3 Earth days. In December 2019, HAT-P-36 was named Tuiren and its planetary companion, HAT-P-36b, was named Bran as a result of Ireland's contribution to the 2019 NameExoWorlds campaign. Bran has a mass approximately 1.8 times that of Jupiter and a radius 1.2 times larger.

Etymology

HAT-P-36 and its planet are named after characters from The Birth of Bran, a story in the book Irish Fairy Tales by James Stephens. The book is a re-telling of various stories from Irish folklore. Tuiren was the aunt of the mythical hero Fionn mac Cumhaill and was turned into a hound by the fairy Uchtdealbh after Tuiren married her husband. Bran and Sceólan were the two puppies mothered by Tuiren while she was a dog. They were cousins of Fionn mac Cumhaill. The names were proposed by John Murphy, a teacher at Regina Mundi College, Cork.

Planetary system HAT-P-36b (Bran) was discovered in 2012 by the HATNet Project using the transit method. A search for transit timing variation did not result in detection of additional planets in the system as at 2021. Surprisingly, a planetary orbital period increase by 0.014 seconds per year was detected by 2021.

Worked examples

Example 1 — a first encounter with HAT-P-36

Start with the simplest possible case. Write down what HAT-P-36 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 HAT-P-36 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 HAT-P-36 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 HAT-P-36

In research: HAT-P-36 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 HAT-P-36 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: HAT-P-36 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Canes Venatici, G-type main-sequence stars, Planetary systems with one confirmed planet, so understanding it makes those chapters shorter.
In everyday life: Look for HAT-P-36 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.

Frequently asked questions

What is HAT-P-36 in simple terms?

Why does HAT-P-36 matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study HAT-P-36?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
