Caloris

Caloris, also known as CelWP G4, is a triple star system, consisting of 3 stars: the red subgiant Abalo (Caloris A), the A-type Luminsar (Caloris B), and the red dwarf Conal (Caloris C). Its also one of the systems with the largest number of planets, totaling 28, one of which (Ontora) hosts the habitable moon Candacia, in the Luminsar subsystem. Its the home system of the Calorean Kingdom, and also notable for its extensive planetary and asteroidal system, while containing several Great Comets.

Stellar system
Caloris is an triple star system, with the primary star being Abalo. However, the main star of the system in terms of notoriety is Luminsar, which is orbited by Conal. The A-BC designation is used when refering to all 3 stars in the system, and BC is used when refering to just the Luminsar-Conal pair.

Orbital properties
Luminsar and Conal are separated by 40 AU, with minimum eccentricity and inclination, and has an orbital period of 178.86 years. The pair and Abalo also orbit each other once every 4772.3 years. Caloris AB-Cs orbit is slightly eccentric, e = 0.1805; their closest approach is 368.77 AU (55.3 billion km), and their furthest separation is 531.23 AU (79.7 billion km). The stars are currently just after periapsis.

Physical properties
The three stars are vastly differet from each other, which makes measuring the age of the Caloris system quite difficult. Due to this, its unknown what are the remaining lifespans of any of the components.

Abalo


Abalo is an late K-type red subgiant, and its well known for its unusually calm and smooth photosphere. Due to this, photospheric mapping was really difficult in early Candacian astronomy, and some astronomers even classified it as an "blank star". The star has nearly exausted all of its hydrogen, and its stellar composition is 46% helium, 52.2% hydrogen, 1.7% metalic elements, and 0.1% others. The relatively high amount of metal is likely due to absorbed planets from back it was an main sequence star.

Luminsar
Luminsar is an late A-type star notable for being the host star of the habitable moon Candacia. Barely edged out by Abalo in terms of mass, Luminsar makes up for it by being the hottest. It also hosts large granules, due to its convoluted convection system.

Conal
Conal is an small M-type red dwarf with its own vast planetary system. Its also a flare star, hindering any chances of life. It also hosts a "scattering" disk of asteroids, which will eventually shrink by a factor of 2-3 due to stability issues.
