HD 115088

HD 115088 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 115088 rather than just read about it. In short: HD 115088, also known as HIP 64951, is a star located in the southern circumpolar constellation Chamaeleon. It has an apparent magnitude of 6.33, placing it near the limit for naked eye visibility.

Key takeaways

HD 115088 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 115088 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 115088 from memory before moving on to harder problems.

Reference excerpt

HD 115088, also known as HIP 64951, is a star located in the southern circumpolar constellation Chamaeleon. It has an apparent magnitude of 6.33, placing it near the limit for naked eye visibility. Based on parallax measurements from the Gaia spacecraft, the object is estimated to be 412 light years distant. At that distance, its brightness is diminished by 0.37 magnitudes due to interstellar dust. HD 115088 has a stellar classification of B9.5/A0 V — intermediate between a B9.5 and A0 main sequence star. It has 2.85 times the mass of the Sun and double the radius of the Sun. It radiates 62.5 times the luminosity of the Sun from its photosphere at an effective temperature of 10,950 K, giving it a bluish-white hue. It is estimated to be 244 million years old, having completed 52.5% of its main sequence lifetime.

Worked examples

Example 1 — a first encounter with HD 115088

Start with the simplest possible case. Write down what HD 115088 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 115088 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 115088 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 115088

In research: HD 115088 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 115088 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 115088 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type main-sequence stars, B-type main-sequence stars, Chamaeleon, so understanding it makes those chapters shorter.
In everyday life: Look for HD 115088 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.
