There are layers, core, convection, photosphere and Corona
Luminosity
Star birth is hidden behind dense clouds of dust and gas.
Main Sequence
As the star forms, it begins fusion where it turns hydrogen into helium and the missing energy creates hydrogen fusion which fuels the star to come to life.
solar flares
Sunspots
Once the star is formed the fusion continues and there is a constant battle between two competing forces, gravity and the pressure caused by nuclear reactions in the core.
The explosion
As the star begins to run out of fuel it can become a red giant. Expanding and cooling before it dies.
Once a star is born, an H-R Diagram is used to graph the temperature and brightness of a star cluster. The movement across the diagonal main sequence can tell us about the past and future of any star.
Temperature
The plasma within the star reaches the surface and then sinks back down. There is magnetic energy and loops go all around the star.
The death is a catastrophic event, it explodes outer layers fly off into space and the inner core collapses down and create a beautiful cloudy wispy thin Planetary Nebula.
