HD 132563

HD 132563 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 132563 rather than just read about it. In short: HD 132563 is a triple star system in the constellation Boötes. The two resolvable components of this system are designated HD 132563A and HD 132563B.

Reference excerpt

HD 132563 is a triple star system in the constellation Boötes. The two resolvable components of this system are designated HD 132563A and HD 132563B. The primary star, HD 132563A, is actually a spectroscopic binary with a period of more than 15 years and an orbital eccentricity of greater than 0.65. The smaller member of this tightly orbiting pair has about 55% the mass of the Sun.

Stellar system

HD 132563 can be resolved into two stars with a separation of 4.1″ and magnitudes of 9.0 and 9.5. These two stars have almost identical distances and proper motions and are widely accepted to form a binary system with a separation of about 400 au. The primary, component A, consists of a star slightly more massive and hotter than the sun and an unseen companion with a mass of about 0.6 M☉. These two stars circle each other in a highly eccentric orbit with separations varying between 2.1 au and 27.5 au Based on evolutionary modelling and isochrone fitting, the primary is right at the end of its main sequence life and starting to expand into a subgiant. Component B is too far from the primary for orbital motion to have been observed, but it is estimated that an orbit would take about 5,000 years. It is main sequence star very similar to the Sun. A further 9th-magnitude star 65" from the primary is listed as component C in the Washington Double Star Catalog, but is much further away from us than the triple system.

Planetary system Based upon radial velocity variations of HD 132563B, the presence of an ordinary giant planet has been inferred by S. Desidera et al. (2011). This object is orbiting the star with a period of 1,544 days, at a distance of about 2.6 AU, and with an orbital eccentricity of 0.22.

Worked examples

Example 1 — a first encounter with HD 132563

Start with the simplest possible case. Write down what HD 132563 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 132563 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 132563 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 132563

In research: HD 132563 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 132563 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 132563 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Boötes, Durchmusterung objects, F-type main-sequence stars, so understanding it makes those chapters shorter.
In everyday life: Look for HD 132563 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.
