HD 106760

HD 106760 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 106760 rather than just read about it. In short: HD 106760 is a single-lined spectroscopic binary star system in the northern constellation of Coma Berenices. It is faintly visible to the naked eye, having an apparent visual magnitude of 4.99.

Key takeaways

HD 106760 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 106760 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 106760 from memory before moving on to harder problems.

Reference excerpt

HD 106760 is a single-lined spectroscopic binary star system in the northern constellation of Coma Berenices. It is faintly visible to the naked eye, having an apparent visual magnitude of 4.99. The system is located around 318 light years away, as determined from its annual parallax shift of 10.2417 mas. It is moving closer with a heliocentric radial velocity of −40 km/s, and is expected to come as close as 259 ly in about 772,000 years. The variable radial velocity of HD 106760 was announced by W. W. Campbell of Lick Observatory in 1922, indicating the binary nature of this system. A preliminary orbit was determined by Mount Wilson Observatory astronomer W. H. Christie in 1936, then refined by English astronomer R. F. Griffin in 1984. The components of this system orbit each other with a period of 3.6 years and an eccentricity of 0.43. The visible component has a stellar classification of K0.5 III–IIIb, indicating it is an evolved K-type giant star. It is around 1.6 billion years old with 1.9 times the mass of the Sun and has expanded to 17 times the Sun's radius. The star is radiating 112 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,581 K.

Worked examples

Example 1 — a first encounter with HD 106760

Start with the simplest possible case. Write down what HD 106760 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 106760 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 106760 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 106760

In research: HD 106760 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 106760 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 106760 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bright Star Catalogue objects, Coma Berenices, Durchmusterung objects, so understanding it makes those chapters shorter.
In everyday life: Look for HD 106760 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.
