HD 114082

HD 114082 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 HD 114082 rather than just read about it. In short: HD 114082 is a young star with a pair of orbiting exoplanetary companions, located in the southern constellation of Centaurus. With an apparent visual magnitude of 8.20, the star is too faint to be visible to the naked eye.

Reference excerpt

HD 114082 is a young star with a pair of orbiting exoplanetary companions, located in the southern constellation of Centaurus. With an apparent visual magnitude of 8.20, the star is too faint to be visible to the naked eye. Based on a parallax shift of 10.52 mas, it is located at a distance of 310.0 ly (95.0 pc). It is a member of the Lower Centaurus-Crux association of co-moving stars.

Properties The star has a stellar classification of F3V, thus presenting as an F-type main-sequence star. However, it is a young star that is still contracting toward the main sequence. Presently, it is located in the instability strip of the H-R diagram near the range where Delta Scuti variables are found, but it exhibits no such pulsational behavior. It is spinning rapidly, with a projected rotational velocity of 39 km/s. HD 114082 has 1.3 times the mass and 1.5 radius of the Sun. It is around 15 million years old and is radiating 3.8 times the luminosity of the Sun from its photosphere at an effective temperature of 6,610 K. Based on the amount of iron appearing in its spectrum, the abundance of elements more massive than helium is similar to that in the Sun.

System

A 2005 study of the Scorpius–Centaurus association with the Spitzer space telescope showed that HD 114082 displays an excess of infrared emission, measured at wavelengths of both 24 μm and 70 μm. This suggested the presence of an orbiting circumstellar disk. The disk image was resolved in 2016 using adaptive optics. It was found to have an inner edge at a radius of 27.7+2.8−3.5 au and is inclined at an angle of 6.7°+3.8°−0.4° to the line of sight from the Earth. The disk density declines outside that radius. Between 2018 and 2022, HD 114082 was examined as part of a radial velocity survey of young stars with debris disks. In 2022, the discovery of a super-Jovian companion was announced. This exoplanet was confirmed by a transit event recorded in TESS photometry. Designated HD 114082 b, it had a preliminary orbit similar to Mercury but more eccentric. However, it was difficult to explain the large mass of this object using currently accepted models of planet formation. A follow-up campaign was used to refine the orbit of the exoplanet. During this process, the transit of a second body was recorded, designated HD 114082 c. The properties of these bodies differ from the earlier model, which was found to be erroneous due to sparse data at the time. Both components are now considered puffy giant planets in near circular orbits. Component 'c' has a wider orbit than component 'b' and is somewhat larger. At discovery, these are the two longest period young transiting exoplanets known. Both are low density bodies and their orbital period ratios are in the range of commensurability at 7:5 and 3:2, suggesting mean motion resonance. A re-examination of the disk in 2026 found the excess infrared emission is consistent with two dust components. The inner belt, orbiting at a loosely-constrained radius of 1.3+1.1−3.8 au, is likely to be dynamically influenced by the two exoplanets to a significant degree. The outer belt is misaligned with the orbital plane of the exoplanet companions by an angle of around 7°. It is likely an exo-Kuiper Belt formation. Here are the modeled physical properties and orbital elements of the two companions as of 2026:

Worked examples

Example 1 — a first encounter with HD 114082

Start with the simplest possible case. Write down what HD 114082 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 HD 114082 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 HD 114082 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 HD 114082

In research: HD 114082 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 HD 114082 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: HD 114082 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Centaurus, Circumstellar disks, Durchmusterung objects, so understanding it makes those chapters shorter.
In everyday life: Look for HD 114082 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.
