HD 96063

HD 96063 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 96063 rather than just read about it. In short: HD 96063 (proper name Dingolay) is a 8th-magnitude red-giant branch star located about 454 light-years (139 pc) away in the constellation of Leo. It is orbited by one confirmed exoplanet, HD 96063 b (proper name Ramajay), a gas giant slightly larger and more massive than Jupiter.

Key takeaways

HD 96063 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HD 96063 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 96063 from memory before moving on to harder problems.

Reference excerpt

HD 96063 (proper name Dingolay) is a 8th-magnitude red-giant branch star located about 454 light-years (139 pc) away in the constellation of Leo. It is orbited by one confirmed exoplanet, HD 96063 b (proper name Ramajay), a gas giant slightly larger and more massive than Jupiter.

Nomenclature In 2019, the Republic of Trinidad and Tobago was assigned to giving the HD 96063 system a proper name as part of the IAU100 NameExoWorlds Project, planned to celebrate the hundredth anniversary of the International Astronomical Union (IAU), which grants the right to name an exoplanetary system to every state and territory in the world. Names were submitted and selected within Trinidad and Tobago, which were then presented to the IAU to be officially recognized. On 17 December 2019, the IAU announced that HD 96063 and its planet, b, were named Dingolay and Ramajay, respectively. The two names are both derived from terms related to the Trinidad and Tobago Carnival. Dingolay is a dance form that represents the culture and language of Trinidad and Tobago's ancestors via intricate movements. Ramajay is a steelpan style of singing and music that celebrates Trinidad and Tobago's forefathers' culture and language.

Stellar characteristics HD 96063 is an evolved yellow/orange star with an effective temperature of about 5,000 K, typical of stars entering the red-giant branch. Its precise nature, however, has been controversial. Once classified as a G6-type main-sequence star, the star is more recently thought to be a K-type "yellow giant," somewhere between three and five times as large as the Sun. When the planet HD 96063 b was discovered, the star was assumed to be 9.0±3.0 billion years old with a sun-like mass (1.020±0.072 M☉), but subsequent studies consider it to be more massive at about 1.4 M☉, and thus younger (2.92±0.81 Gyr). With a luminosity roughly ten times that of the Sun and a distance of 454 light-years, the star has an apparent magnitude of 8.254, too faint to be seen from Earth by the naked eye.

Planetary system In 2011, radial-velocity observations made at the W. M. Keck Observatory revealed the existence of an exoplanet around HD 96063. The planet, HD 96063 b, is thought to be a gas giant at least 1.265 times the mass of Jupiter, which orbits its host star at a distance of 1.11 AU with an Earth-like period of 362 days. Its orbit is moderately eccentric, with an eccentricity comparable to that of planet Mercury (0.2056).

Worked examples

Example 1 — a first encounter with HD 96063

Start with the simplest possible case. Write down what HD 96063 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 96063 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 96063 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 96063

In research: HD 96063 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 96063 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 96063 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Durchmusterung objects, Henry Draper Catalogue objects, Hipparcos objects, so understanding it makes those chapters shorter.
In everyday life: Look for HD 96063 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.
