HD 134064

HD 134064 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 HD 134064 rather than just read about it. In short: HD 134064 is a triple star system in the northern constellation of Boötes. It is faintly visible to the naked eye with a combined apparent visual magnitude of 6.03.

Key takeaways

HD 134064 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HD 134064 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 134064 from memory before moving on to harder problems.

Reference excerpt

HD 134064 is a triple star system in the northern constellation of Boötes. It is faintly visible to the naked eye with a combined apparent visual magnitude of 6.03. This system is located at a distance of 247 light years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of –7.0 km/s. HD 134064 can be resolved into two stars 110″ apart. The brighter primary is itself a close binary that has not been resolved into individual stars. The two inner components of this system are orbiting each other with a period of eight years and a high orbital eccentricity of 0.45. The pair are separated by an orbital distance of around 8,000 AU. The primary component is a rapidly rotating A-type main sequence star with a stellar classification of A3Vnn. It has 2.15 times the mass of the Sun and is spinning with a projected rotational velocity of 185 km/s. The secondary star has 73% of the Sun's mass. The system is young, with an estimated age of 160 million years. The fainter resolved component C is magnitude 11.39 and is less massive than the Sun.

Worked examples

Example 1 — a first encounter with HD 134064

Start with the simplest possible case. Write down what HD 134064 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 HD 134064 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 HD 134064 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 HD 134064

In research: HD 134064 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 HD 134064 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: HD 134064 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type main-sequence stars, Boötes, Bright Star Catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for HD 134064 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.
