Osis/Luthier

Luthier, also known as Osis A, is the primary star in the Osis star system. It is known to host 2 planets, with many more unconfirmed.

= Current status =

Luthier is a main-sequence star more massive than the Sun, meaning it is currently fusing hydrogen into helium primary through the CNO cycle.

= Anomalies =

Luthier, despite being only 3 gigayears old, seems to have less metal content than the Sun, which is around 4.5 gigayears old. This is abnormal, because typically the metal content in the universe slowly incrases with age; stars born younger should have more metals.

= Planets =
