The Algieba star system (otherwise known as Gamma Leonis) is composed of a binary pair of giant stars: Algieba A (an orange K0 III giant), and Algieba B (an odd greenish-yellow G7 III giant).
Description (Specifications)
The stars of the Algieba system are separated by about 170AU, and have an orbital period of 510.3 years.
- The binary stars of this system are characterized by a highly eccentric orbit about one another (e=0.845).
- Both stars are almost certainly true giants, meaning that they have stopped fusing hydrogen to helium in their cores, and their outer layers have expanded to great proportions as a result of the slow collapse and heating up of their cores as helium fusion has begun.
The Algieba star system is approximately 40.0pc from Terra, and is located in a Rimward direction from Terra at bearing 216.6o Galactic Longitude and +54.7o North Galactic Latitude.
History & Background (Dossier)
