SN 2016aps

SN 2016aps 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 SN 2016aps rather than just read about it. In short: SN 2016aps (also known as PS16aqy and AT2016aps) is the brightest and most energetic supernova explosion ever recorded. It released more energy than ASASSN-15lh.

Key takeaways

SN 2016aps belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SN 2016aps to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SN 2016aps from memory before moving on to harder problems.

Reference excerpt

SN 2016aps (also known as PS16aqy and AT2016aps) is the brightest and most energetic supernova explosion ever recorded. It released more energy than ASASSN-15lh. In addition to the sheer amount of energy released, an unusually large amount of the energy was released in the form of radiation, probably due to the interaction of the supernova ejecta and a previously lost gas shell.

Overview The event was discovered on 22 February 2016 by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) in Hawaii, with follow-up observations by the Hubble Space Telescope. The supernova occurred at a high z-value indicating a distance of 3.6 billion light-years. and is located in the constellation Draco. The maximum apparent magnitude was 18.11, the corresponding absolute magnitude −22.35. The progenitor star is estimated to have had at least 50 to 100 solar masses. The spectrum of SN 2016aps revealed significant amounts of hydrogen, which is unexpected for supernovae of this type, which usually occur after nuclear fusion has consumed most of the star's hydrogen and the stars have shed the remaining hydrogen atmosphere. This led researchers to the theory that the progenitor star formed only shortly before the event from the merger of two very large stars, creating a "pulsational pair instability" supernova or possibly a full pair instability supernova.

Worked examples

Example 1 — a first encounter with SN 2016aps

Start with the simplest possible case. Write down what SN 2016aps 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 SN 2016aps 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 SN 2016aps 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 SN 2016aps

In research: SN 2016aps 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 SN 2016aps 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: SN 2016aps is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 2016, Draco (constellation), Type II supernovae, so understanding it makes those chapters shorter.
In everyday life: Look for SN 2016aps 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.
