LHS 1815 b

LHS 1815 b 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 LHS 1815 b rather than just read about it. In short: LHS 1815 b (also known as TOI-704 b) is a thick disk exoplanet discovered in 2020 by TESS. The planet is located outside the galactic plane.

Key takeaways

LHS 1815 b belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect LHS 1815 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of LHS 1815 b from memory before moving on to harder problems.

Reference excerpt

LHS 1815 b (also known as TOI-704 b) is a thick disk exoplanet discovered in 2020 by TESS. The planet is located outside the galactic plane.

Characteristics LHS 1815 b is a terrestrial planet (super-Earth) with a mass of 0.0132 MJ and a radius of 0.09707 RJ, discovered by TESS in 2020. It is the first known example of a "thick-disk planet" located within the galactic thick disk, a structure much higher than the positions of other planetary systems discovered by TESS."

Orbit The orbital period is 3.81433 days and the semimajor axis is 0.0404 au.

Other designations LHS 1815 b is also known as TOI-704 b and TIC 260004324 b.

Worked examples

Example 1 — a first encounter with LHS 1815 b

Start with the simplest possible case. Write down what LHS 1815 b 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 LHS 1815 b 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 LHS 1815 b 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 LHS 1815 b

In research: LHS 1815 b 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 LHS 1815 b 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: LHS 1815 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanet stubs, Exoplanets discovered by TESS, Exoplanets discovered in 2020, so understanding it makes those chapters shorter.
In everyday life: Look for LHS 1815 b 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.
