Bessel Star System

Bessel contains 11 resources.

The Bessel star system in Starfield is named after the German astronomer Friedrich Bessel.

Friedrich Bessel was a 19th-century German astronomer and mathematician known for several significant contributions to both fields.

Stellar Parallax: Friedrich Bessel is best remembered for being the first to determine the parallax of a star, specifically 61 Cygni. In 1838, he accurately measured its tiny angular shift due to Earth's orbit around the Sun. This achievement provided the first direct evidence for the vast distances of stars and was the first step in measuring the scale of the universe.

Bessel Functions: In mathematics, Bessel is renowned for his work leading to the introduction of Bessel functions. These are solutions to a specific differential equation, and they arise in various physical situations, especially in problems with cylindrical symmetry. They have applications in many areas, including optics, electromagnetic theory, and mechanical vibrations, to name a few.

Bessel Telescope: Bessel also made refinements to the design of the heliometer, a type of telescope used to measure the variation in position of stars.

Besselian Elements: In the context of solar eclipses, Besselian elements are a set of time-dependent values that provide a concise description of the position and motion of the Moon's shadow. These elements are used to predict the circumstances of solar eclipses.
