HD 106112

HD 106112 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 106112 rather than just read about it. In short: HD 106112, also known as CO Camelopardalis, is a star in the constellation Camelopardalis. It has an apparent magnitude of about 5.1, meaning that it is just barely visible to the naked eye.

Key takeaways

HD 106112 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 106112 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 106112 from memory before moving on to harder problems.

Reference excerpt

HD 106112, also known as CO Camelopardalis, is a star in the constellation Camelopardalis. It has an apparent magnitude of about 5.1, meaning that it is just barely visible to the naked eye. Based upon parallax measurements made by the Hipparcos spacecraft, this star is around 177 light years away from the Sun. HD 106112's spectral type shows that it is an A-type giant star. HD 106112 is also an Am star, also known as a metallic-line star. These types of stars have spectra indicating varying amounts of metals, like iron. Observations of the stars spectrum reveal a periodic Doppler shift. This means that HD 106112 is a spectroscopic binary with a period of 1.271 days and an eccentricity of 0.01. Eric Steinbring et al. discovered that the star is a variable star, in 1995. It was given its variable star designation, CO Camelopardalis, in 1997. The two stars orbit so closely that they distort each other into an ellipsoidal shape through gravity, thereby forming a rotating ellipsoidal variable system. However, almost no information is known about the companion star.

Worked examples

Example 1 — a first encounter with HD 106112

Start with the simplest possible case. Write down what HD 106112 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 106112 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 106112 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 106112

In research: HD 106112 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 106112 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 106112 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type main-sequence stars, Bright Star Catalogue objects, Camelopardalis, so understanding it makes those chapters shorter.
In everyday life: Look for HD 106112 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.
