Adjust the initial mass of the collapsing protostar cloud to see how mass determines the star's properties and lifespan on the main sequence.
0.5 M☉1.0 M☉15.0 M☉
Color / Temp:Yellow (Moderate)
Relative Lifespan:Moderate (~10 Billion Years)
Primary Fuel: Hydrogen
Gravity vs. Fusion Pressure Balanced
Core Fusion Simulator
Inside the core of a 1.0 M☉ Yellow Star. Observe how hydrogen nuclei collide to form helium, releasing energy.

Missing Mass:0%
Result: 4 Hydrogen Nuclei fuse into 1 Helium Nucleus.
Energy Released: The Helium nucleus has slightly less mass than the inputs. This "missing mass" is converted directly into a photon of electromagnetic radiation (E = mc²).
Stellar Fate Simulator
Select a star and fast-forward millions/billions of years to observe its final evolutionary stage and the elements it creates.
