SN 2010lt

SN 2010lt 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 2010lt rather than just read about it. In short: SN 2010lt is a supernova located in the galaxy UGC 3378 in Camelopardalis. It was discovered by amateur astronomers Kathryn Aurora Gray, her father Paul Gray, of Fredericton, New Brunswick, Canada and David J.

Key takeaways

SN 2010lt 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 2010lt to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SN 2010lt from memory before moving on to harder problems.

Reference excerpt

SN 2010lt is a supernova located in the galaxy UGC 3378 in Camelopardalis. It was discovered by amateur astronomers Kathryn Aurora Gray, her father Paul Gray, of Fredericton, New Brunswick, Canada and David J. Lane of Stillwater Lake, Nova Scotia, Canada. Upon discovery, Kathryn Aurora Gray became the youngest person to ever discover a supernova, being 10 years old when she did so. The previous record was held by the 14-year-old Caroline Moore.

Discovery The images were taken at Lane's Abbey Ridge Observatory on 31 December 2010 with a Celestron C14 0.36-meter f/5.5 telescope, and the supernova was spotted by them on 2 January 2011. The discovery was confirmed on 3 January 2011 by the amateur astronomers Brian Tieman and Jack Newton and announced by the IAU Central Bureau of Astronomical Telegrams at the Harvard–Smithsonian Center for Astrophysics, Cambridge, Massachusetts. It was announced by the Royal Astronomical Society of Canada on the same day.

Discoverers David J. Lane: SN 2010lt is Lane's fourth discovery of a supernova. The previous were SN 1995F, SN 2005B and SN 2005ea. All were discovered with Paul Gray. Paul Gray: SN 2010lt is his seventh discovery of a supernova. Kathryn Aurora Gray: her first discovery.

Description SN 2010lt is about 20" west and 10" north of the galaxy center. It is a sub-luminous (1991bg-like) type Ia supernova and was discovered when near maximum light. The supernova could not be detected (detection limit approximately 18.5 of apparent magnitude) at its current position on images taken between October 2005 and March 2006.

Worked examples

Example 1 — a first encounter with SN 2010lt

Start with the simplest possible case. Write down what SN 2010lt 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 2010lt 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 2010lt 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 2010lt

In research: SN 2010lt 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 2010lt 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 2010lt is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 2011, Camelopardalis, Type Ia supernovae, so understanding it makes those chapters shorter.
In everyday life: Look for SN 2010lt 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.
