Reference excerpt

KIC 3542116 (also called TYC 3134-1024-1) is an F-type star in the constellation Lyra. Around this star the first detection of transiting exocomets were made in 2018.

Host star KIC 3542116 has a spectral type of F2V from spectroscopy taken at the Fred Lawrence Whipple Observatory. While the star does not show clear signs of being young, the scientists suspect the star to be young. The star is co-moving with a M1.9-type red dwarf called KOI-4987 (KIC 3542117); a planet candidate around this star, KOI-4987.01, is a false positive. This star has an 23 day rotation that leaks into the Kepler light curve of KIC 3542116.

Exocomets

The employment consultant and citizen scientists of the Planet Hunters project Thomas Jacobs did look through light curves of 201,250 target stars from the Kepler Space Telescope and found three potential transiting exocomets around KIC 3542116. Three more shallow transits were later discovered in the light curve. Transiting exocomets were already modelled in the 90s by A. Lecavelier Des Etangs et al. This team predicted a rounded triangular shape that is distinct from transiting exoplanets. The team of scientists found just such a shape, with a "steeper ingresses with positive curvature, followed by longer egresses with negative curvature" for the three deeper transits. The transits were later also detected in an automated search for exocomets. Another work did detect 8 transits in total (including previous detected transits). Modelling did show that the transits agree well with known comets from the Solar System, such as Halley's Comet, comet Hale–Bopp and C/2006 S3 (LONEOS). The shallow transits are produced by comets moving closer to the star (about 1 astronomical unit) and produce dust particles with a size of 0.1 and 20 μm. The deeper transits are produced by comets orbiting further away (around 5 astronomical units) and produce larger dust particles with a size greater than 5 μm. The study has shown that the shape of the transit is influenced by a varaiety of factors, such as particle size, distribution and distance to the star. The depth and duration of the transit is influenced by the dust productivity of the comet nucleus and the impact parameter. The dust productivity is higher for exocomets with shallow dips that orbit the star closer.

Worked examples

Example 1 — a first encounter with KIC 3542116

Start with the simplest possible case. Write down what KIC 3542116 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 KIC 3542116 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 KIC 3542116 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 KIC 3542116

In research: KIC 3542116 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 KIC 3542116 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: KIC 3542116 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Comets, Exoplanetology, F-type main-sequence stars, so understanding it makes those chapters shorter.
In everyday life: Look for KIC 3542116 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.
