OGLE-2016-BLG-1190Lb

OGLE-2016-BLG-1190Lb 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-2016-BLG-1190Lb rather than just read about it. In short: OGLE-2016-BLG-1190Lb is an extremely massive exoplanet, with a mass about 13.4 times that of Jupiter (MJ), or is, possibly, a low mass brown dwarf, orbiting the G-dwarf star OGLE-2016-BLG-1190L, located about 22,000 light years from Earth, in the constellation of Sagittarius, in the galactic bulge of the Milky Way. “Since the existence of the brown dwarf desert is the signature of different formation mechanisms for…

Reference excerpt

OGLE-2016-BLG-1190Lb is an extremely massive exoplanet, with a mass about 13.4 times that of Jupiter (MJ), or is, possibly, a low mass brown dwarf, orbiting the G-dwarf star OGLE-2016-BLG-1190L, located about 22,000 light years from Earth, in the constellation of Sagittarius, in the galactic bulge of the Milky Way. “Since the existence of the brown dwarf desert is the signature of different formation mechanisms for stars and planets, the extremely close proximity of OGLE-2016-BLG-1190Lb to this desert raises the question of whether it is truly a ‘planet’ (by formation mechanism) and therefore reacts back upon its role tracing the galactic distribution of planets," according to astronomers reporting the findings.

Discovery The host star was discovered in June 2016 by the Optical Gravitational Lensing Experiment (OGLE) collaboration; the Spitzer Space Telescope observed the microlensing event a few days after its discovery. OGLE-2016-BLG-1190Lb is the first exoplanet discovered by microlensing with the Spitzer space telescope and the first exoplanet discovered lying near the planet/brown dwarf boundary. In addition, the discovery "is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar," according to the initial reported study.

Worked examples

Example 1 — a first encounter with OGLE-2016-BLG-1190Lb

Start with the simplest possible case. Write down what OGLE-2016-BLG-1190Lb 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-2016-BLG-1190Lb 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-2016-BLG-1190Lb 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-2016-BLG-1190Lb

In research: OGLE-2016-BLG-1190Lb 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-2016-BLG-1190Lb 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-2016-BLG-1190Lb is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets detected by microlensing, Exoplanets discovered in 2017, Sagittarius (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for OGLE-2016-BLG-1190Lb 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.
