Kamil Hornoch

Kamil Hornoch 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 Kamil Hornoch rather than just read about it. In short: Kamil Hornoch (Czech pronunciation: [ˈkamɪl ˈɦornox]; born 5 December 1972) is a Czech astronomer who discovered dozens of novae in nearby galaxies. The main belt asteroid 14124 Kamil is named in his honour.

Key takeaways

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

Reference excerpt

Kamil Hornoch (Czech pronunciation: [ˈkamɪl ˈɦornox]; born 5 December 1972) is a Czech astronomer who discovered dozens of novae in nearby galaxies. The main belt asteroid 14124 Kamil is named in his honour.

Astronomy Kamil Hornoch became interested in astronomy in 1984. One year later he started with his scientific observations of comets, meteors, the solar photosphere, variable stars, the planets and occultations. He lives in Lelekovice, a village in the South Moravian Region, the Czech Republic. Hornoch makes most of his observations from a small observatory in Lelekovice with a 35 cm (14 in) reflector telescope. Although he uses a CCD camera, he is also good in visual estimates of star luminosity, reaching an accuracy of 0.03 magnitude (confirmed by separate photoelectric measurements). He has also been acknowledged for his numerous estimates and measurements of brightness and positions of comets and variable stars, as well as position measurements of minor planets. In 1993 he co-discovered (with Jan Kyselý) new variable star ES UMa. He is a member of the Czech Astronomical Society. Since 2007 he works as a professional astronomer at the Ondřejov Observatory.

Novae In the summer of 2002, Hornoch took a series of pictures of the surrounding of the core of the Andromeda Galaxy and discovered his first extragalactic nova. Since that time, galaxy M31 has become his favourite place to observe; he has made 43 nova discoveries and co-discoveries in that region (as of May 2007). He also discovered two novae in the galaxy M81 in pictures taken by Czech astronomer Pavel Cagaš with his 26.5 cm (10.4 in) reflector telescope on 8 and 11 April 2007. No nova discovery had been made with such a small telescope in such a distance before. One of the novae, M81 2007 3, grew very luminous, reaching the quite extraordinary absolute magnitude of −10 and apparent magnitude of 17.6 six days later. It was the brightest nova ever discovered in M81.

Awards In 1996 Kamil Hornoch became the first person to receive the newly established Zdeněk Kvíz Award of the Czech Astronomical Society for his activities in the field of interplanetary matter. In 2001 Lenka Šarounová named the main belt asteroid 14124 Kamil in his honour. In 2003 he received the Jindřich Šilhán Award of the Variable Star Observer of the Year (Czech: Cena Jindřicha Šilhána Proměnář roku) of the Czech Astronomical Society. In 2006 Kamil Hornoch won the Amateur Achievement Award of the Astronomical Society of the Pacific.

Worked examples

Example 1 — a first encounter with Kamil Hornoch

Start with the simplest possible case. Write down what Kamil Hornoch 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 Kamil Hornoch 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 Kamil Hornoch 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 Kamil Hornoch

In research: Kamil Hornoch 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 Kamil Hornoch 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: Kamil Hornoch is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, 20th-century astronomers, 21st-century astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Kamil Hornoch 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.
