Formation and Stellar Genesis
Stars/) originate within dense regions of molecular clouds, vast reservoirs of interstellar medium composed primarily of molecular hydrogen ($\text{H}_2$) and helium, along with trace amounts of heavier elements (metals) and microscopic silicate motes [1]. Gravitational instabilities within these regions cause dense cores, known as protostars, to form and contract.
The initiation of sustained [fus… -

Stellar Structure and Energy Transport
A typical star/) possesses a highly stratified structure, organized by pressure and temperature gradients. The primary layers include the core)/), radiative zone, convective zone, and the photosphere, the visible surface.
