PS1-10adi

PS1-10adi 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 PS1-10adi rather than just read about it. In short: PS1-10adi is an unusual and highly energetic optical transient discovered by the Pan-STARRS survey on 15 August 2010. The explosion or transient event emitted 2.3×1052 ergs (2.3×1045 Joules), exceeding ASASSN-15lh.

Key takeaways

PS1-10adi belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PS1-10adi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PS1-10adi from memory before moving on to harder problems.

Reference excerpt

PS1-10adi is an unusual and highly energetic optical transient discovered by the Pan-STARRS survey on 15 August 2010. The explosion or transient event emitted 2.3×1052 ergs (2.3×1045 Joules), exceeding ASASSN-15lh. It may be a superluminous supernova or a stellar disruption event. The magnitude of the explosion challenges the limits of the current models for theoretical physics. The event happened near the centre of J204244.74+153032.1 (a point in Delphinus, specifically right ascension in usual sexagesimal and then declination in decimal terms, with the point/spacing moved four places to the right in both cases). The optical transient peaked at two magnitudes brighter than its host galaxy, and remained brighter for 1000 days. Its distance can be implied by its galaxy's red shift of 0.203. Balmer emission lines due to hot hydrogen showed relative motions of up to 900 km/s. The lines also had a red shoulder. There was also a hot black body continuum spectrum showing temperatures dropping from 11,000K. No X-rays or radio waves were detected from the source. Similar optical transients include PS1-13jw, CSS100217, J094806, J094608, and J233454.

Worked examples

Example 1 — a first encounter with PS1-10adi

Start with the simplest possible case. Write down what PS1-10adi 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 PS1-10adi 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 PS1-10adi 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 PS1-10adi

In research: PS1-10adi 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 PS1-10adi 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: PS1-10adi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Delphinus, Discoveries by Pan-STARRS, Hypernovae, so understanding it makes those chapters shorter.
In everyday life: Look for PS1-10adi 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.
