If your referring to Stellar Nucleosynthesis, then its when stars fuse the smaller elements (Hydrogen,Helium) to make the heavier elements (iron, gold, silver,zinc, etc).
The Stellar Theory is a historical scientific theory that suggested stars generate energy through the process of gravitational contraction. Proposed by scientists like Kelvin and Helmholtz in the 19th century, it was later replaced by the theory of nuclear fusion as the primary energy source for stars.
Stellar Collision Theory suggests that some exotic celestial events, such as the creation of blue stragglers or some types of supernovae, can occur when two stars collide with each other. This theory is based on the idea that the merger of two stars can result in a new, more massive star with unique characteristics. While actual observations of stellar collisions are rare, computational simulations support the idea that such events can occur in dense stellar environments.

Svein Rosseland was a Norwegian astrophysicist known for his work on the theory of stellar atmospheres and effectively explaining the structure of stars. His notable contributions include developing the Rosseland mean opacity used in stellar atmospheres and radiation transfer theory.
