HATS-36b

HATS-36b 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 HATS-36b rather than just read about it. In short: HATS-36b is a gas giant exoplanet that orbits an F-type star. Its mass is 3.216 Jupiters, it takes 4.2 days to complete one orbit of its star, and is 0.05425 AU from it.

Key takeaways

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

Reference excerpt

HATS-36b is a gas giant exoplanet that orbits an F-type star. Its mass is 3.216 Jupiters, it takes 4.2 days to complete one orbit of its star, and is 0.05425 AU from it. It was discovered on June 12, 2017 and was announced in 2018. Its discoverers were 23, namely Daniel Bayliss, Joel Hartman, George Zhou, Gaspar Á. Bakos, Andrew Vanderburg, J. Bento, L. Mancini, S. Ciceri, Rafael Brahm, Andres Jordán, N. Espinoza, M. Rabus, T. G. Tan, K. Penev, W. Bhatti, M. de Val-Borro, V. Suc, Z. Csubry, Th. Henning, P. Sarkis, J. Lázár, I. Papp, P. Sári.

Host star The exoplanet HATS-36 b which orbits the star HATS-36 is located about 3,186.5 light-years (977 parsecs) away from Solar System. It is situated in the constellation of Sagittarius. The host star HATS-36 has apparent magnitude of 14.4, with absolute magnitude of 4.4. The surface temperature is 5970 K with its spectral types of G0V class. In this planetary system, the extra-solar planet orbits around the star HATS-36 every 4.17524 days with its orbital distance of 0.05 AU (7.5 million km).

Discovery After the discovery of HATS-36b, it became one of the 25 HATSouth candidates on Campaign 7 of the K2 mission. It detects that the exoplanet, a hot Jupiter-like planet with a mass of 2.790.40 MJ and a radius of 1.2630.045 RJ, transits a solar-type G0V star (V = 14.386) in a 4.17524-day period. The planetary system of HATS-36 is classified as an eclipsing binary system based on a combination of the HATSouth data, the K2 data, and follow-up ground-based photometry and spectroscopy.

Discussion HATS-36b has a typical orbital period of 4.1752379 ± 0.0000021 days and has a density of 2.12 ± 0.20 g/cm3. Its star is active, which can be seen and manifested in both the variability in the LC and the high jitters in the radial velocity measurements. Due to its high mass compared with the known population of hot Jupiters, HATS-36b lies in a relatively sparsely populated region of the mass-density relationship for gas giant exoplanets. However, its bulk density fits well on the mass-density sequence of the related exoplanets.

Worked examples

Example 1 — a first encounter with HATS-36b

Start with the simplest possible case. Write down what HATS-36b 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 HATS-36b 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 HATS-36b 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 HATS-36b

In research: HATS-36b 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 HATS-36b 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: HATS-36b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by HATNet, Exoplanets discovered in 2017, Giant planets, so understanding it makes those chapters shorter.
In everyday life: Look for HATS-36b 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.
