Star systems

A star system, often referred to as a stellar system, is a group of celestial bodies that are gravitationally bound to a central star. The most recognizable type of star system is a solar system, which includes a star (or multiple stars in the case of binary or multiple star systems) and various objects such as planets, moons, asteroids, comets, and meteoroids that orbit the star.

Binary stars are systems consisting of two stars that are bound together by their mutual gravitational attraction and orbit a common center of mass. These systems can be classified into several types based on the nature of their orbits and the way they are observed: 1. **Visual Binaries**: These binary stars can be distinguished as separate stars through a telescope. They are visually observable, and their orbits can be tracked over time.

Multiple star systems are stellar systems that consist of two or more stars that are gravitationally bound to each other. Unlike single stars like our Sun, which exist in isolation, multiple star systems can vary in their configurations and can include: 1. **Binary Stars**: The simplest form of a multiple star system, consisting of two stars orbiting around a common center of mass. These can be further classified into: - **Wide binaries**: Stars that are separated by large distances.

Multiple stars are a group of two or more stars that are physically related and bound by gravity. They can exist in several configurations, categorized primarily into binary stars, triple stars, and higher-order systems. Here are the main types of multiple stars: 1. **Binary Stars**: These systems consist of two stars orbiting around a common center of mass. They can be further classified into: - **Visual Binaries**: Stars that can be distinguished from one another through a telescope.

Triple star systems are a type of astronomical system that consists of three stars gravitationally bound to each other. These systems can take various forms, depending on the distances between the stars and their orbital configurations. Here are some key features and types of triple star systems: 1. **Hierarchical Structure**: Many triple systems have a hierarchical structure, where two stars (the binary pair) orbit closely around each other while the third star orbits at a greater distance.

A central massive object typically refers to a large celestial body, usually a star, black hole, or a supermassive black hole, that is located at the center of a galaxy or a star cluster. In astrophysics, the term is often used in the context of galaxy dynamics and structure.

HD 155448 is a star located in the constellation of Centaurus, which is about 140 light-years away from Earth. It is classified as a G-type main sequence star, similar to our Sun. The star is noteworthy for being part of a binary system, hosting a companion star.

A star system, also known as a stellar system, is a group of celestial bodies that are gravitationally bound to a central star or stars. This can include various objects like planets, moons, asteroids, comets, and meteoroids. Star systems can range from single-star systems, like our Solar System centered around the Sun, to multiple-star systems, which can contain two or more stars orbiting each other.
