Open Exoplanet Catalogue

Open Exoplanet Catalogue 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 Open Exoplanet Catalogue rather than just read about it. In short: The Open Exoplanet Catalogue is a catalogue of all discovered extra-solar planets. It is a new kind of astronomical database decentralized and completely open.

Key takeaways

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

Reference excerpt

The Open Exoplanet Catalogue is a catalogue of all discovered extra-solar planets. It is a new kind of astronomical database decentralized and completely open. It is considered one of the four exoplanet catalogues most widely used, together with the Extrasolar Planets Encyclopaedia, the NASA Exoplanet Archive, and the Exoplanet Data Explorer. In 2012, Hanno Rein presented a new kind of astronomical database based on small text files and a distributed version control system. In 2016, Ryan Varley presented ExoData, Python interface and exploratory analysis tool for the Open Exoplanet Catalogue.

Statistics As of October 2020, the Open Exoplanet Catalogue has the following statistics:

Worked examples

Example 1 — a first encounter with Open Exoplanet Catalogue

Start with the simplest possible case. Write down what Open Exoplanet Catalogue 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 Open Exoplanet Catalogue 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 Open Exoplanet Catalogue 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 Open Exoplanet Catalogue

In research: Open Exoplanet Catalogue 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 Open Exoplanet Catalogue 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: Open Exoplanet Catalogue is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanet catalogues, so understanding it makes those chapters shorter.
In everyday life: Look for Open Exoplanet Catalogue 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.
