HD 95086

HD 95086 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 95086 rather than just read about it. In short: HD 95086, formally named Aiolos, is a pre-main-sequence star about 282 light-years (86 parsecs) away. Its surface temperature is 7,750±250 K.

Key takeaways

HD 95086 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 95086 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 95086 from memory before moving on to harder problems.

Reference excerpt

HD 95086, formally named Aiolos, is a pre-main-sequence star about 282 light-years (86 parsecs) away. Its surface temperature is 7,750±250 K. HD 95086 is somewhat metal-deficient in comparison to the Sun, with a metallicity Fe/H index of −0.25±0.5 (~55%), and is much younger at an age of 13.3 million years. It was originally thought to be part of the Lower Centaurus-Crux association, until it was found using Gaia data that the star may be instead part of the Carina association. Multiplicity surveys did not detect any stellar companions to HD 95086 as of 2013.

Nomenclature The designation HD 95086 comes from the Henry Draper Catalogue. In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project. The approved names, proposed by a team from Greece, were announced in June 2023. HD 95086 is named Aiolos after a Greek mythological figure, and its planet is named Levantes, from a modern Greek word referring to easterly Mediterranean winds.

Planetary system In 2013, one planet, named HD 95086 b, was discovered on a wide orbit by direct imaging. The discovery was confirmed in 2014. Besides the planet, the star is surrounded by a complex, relatively massive (0.5±0.2 M🜨) debris disk, which may consist of up to four belts (Hot, Warm, Cold and Halo) separated by gaps. A small amount (1.4–13)×10−6 M🜨 of gaseous carbon monoxide was detected in the outer disk, implying a recent collisional cascade followed by cometary activity of fresh debris.

Worked examples

Example 1 — a first encounter with HD 95086

Start with the simplest possible case. Write down what HD 95086 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 95086 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 95086 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 95086

In research: HD 95086 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 95086 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 95086 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type pre-main-sequence stars, Carina (constellation), Circumstellar disks, so understanding it makes those chapters shorter.
In everyday life: Look for HD 95086 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.
