HD 164595 b

HD 164595 b 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 164595 b rather than just read about it. In short: HD 164595 b is a confirmed exoplanet orbiting around a Sun-like star HD 164595 every 40 days some 94.36 light-years away. It was detected with the radial velocity technique with the SOPHIE echelle spectrograph.

Key takeaways

HD 164595 b 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 164595 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 164595 b from memory before moving on to harder problems.

Reference excerpt

HD 164595 b is a confirmed exoplanet orbiting around a Sun-like star HD 164595 every 40 days some 94.36 light-years away. It was detected with the radial velocity technique with the SOPHIE echelle spectrograph. The planet has a minimal mass equivalent of 16 Earths. It is speculated to be a Neptune-like gassy planet incapable of supporting life. The planet has a minimal mass of 16 Earth masses.

Possible radio signal from star system

A recent (2016) radio signal at 11 GHz (2.7 cm wavelength) has been observed from the HD 164595 stellar system. It is unknown which planet of that stellar system is involved, if any. It could instead be gravitational lensing from a more distant source. SETI investigators are looking into it, but the chances of the signal being from an extraterrestrial civilization are considered slim, at best," with SETI researcher Eric Korpela calling it "uninteresting".

Worked examples

Example 1 — a first encounter with HD 164595 b

Start with the simplest possible case. Write down what HD 164595 b 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 164595 b 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 164595 b 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 164595 b

In research: HD 164595 b 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 164595 b 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 164595 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets detected by radial velocity, Exoplanets discovered in 2015, Giant planets, so understanding it makes those chapters shorter.
In everyday life: Look for HD 164595 b 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.
