OGLE-TR-132b

OGLE-TR-132b 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 OGLE-TR-132b rather than just read about it. In short: OGLE-TR-132b is an extrasolar planet orbiting the star OGLE-TR-132. In 2003 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.

Key takeaways

OGLE-TR-132b belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OGLE-TR-132b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OGLE-TR-132b from memory before moving on to harder problems.

Reference excerpt

OGLE-TR-132b is an extrasolar planet orbiting the star OGLE-TR-132. In 2003 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object. Since low-mass red dwarfs and brown dwarfs may mimic a planet radial velocity measurements were necessary to calculate the mass of the body. In 2004 the object was proved to be a new transiting extrasolar planet. The planet has a mass 1.14 times that of Jupiter. Since the planet's inclination is known, this represents the best measured true mass of the planet, rather than simply the minimum mass as is the case when the inclination is unknown. It orbits the star (OGLE-TR-132) in an extremely close orbit, even closer than the famous planets 51 Pegasi b and HD 209458 b. The planet races around the star every 1 day 16.6 hours. The radius of the planet is only 18% larger than Jupiter's, despite the heating effect by the star. Planets of its kind are sometimes called "super-hot Jupiters".

Worked examples

Example 1 — a first encounter with OGLE-TR-132b

Start with the simplest possible case. Write down what OGLE-TR-132b 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 OGLE-TR-132b 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 OGLE-TR-132b 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 OGLE-TR-132b

In research: OGLE-TR-132b 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 OGLE-TR-132b 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: OGLE-TR-132b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carina (constellation), Exoplanet stubs, Exoplanets discovered in 2004, so understanding it makes those chapters shorter.
In everyday life: Look for OGLE-TR-132b 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.
