Shock wave , compression, condensation

Asymmetric magnetism, emergent protostar

Protostar contraction causes thermonuclear reaction

Chandrasekhar limit, HR, main sequence star

Main sequence for a billion years

Hydrogen depletion, contraction begins

Compression overcomes expansion to commence

Turn off point, main sequence is left

Constant luminosity hides hydrogen expansion

A billion years pass until the helium flash

Triple-alpha process causеs shrinkage in size

A planetary nеbula is discharged and dies

Nucleosythesis shock wave charges surface

Uncontainable supernova bursts forth

Most of its mass is lost stellar pentecost

White dwarf dies, neutron star survives

Or a blackened hole
