Fluctuates in brightness.

The ionized gas can glow a certain color, giving clues about the star.

And, how do stars make energy? anthony_sobeck https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220451432 When a shock passes through the interstellar medium, it can compress sections into dense clouds. Eventually, these clouds collapse under their own gravity and enter the free-fall phase which heats up the forming protostar. Eventually, once the protostar becomes hot enough, it can start to undergo nuclear fusion and convert atoms into different elements to sustain itself. Now the protostar is becoming a full-fledged star and will use the energy created in the CNO cycle and tri-alpha process to fuel itself for millennia to come.]]> 2018-01-11 04:36:18 UTC https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220451432 anthony_sobeck https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220454275 2018-01-11 05:08:40 UTC https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220454275 How do stars maintain stability? anthony_sobeck https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220455678 Due to the law of hydrostatic equilibrium, a star must be warm on the inside to maintain the pressure so it doesn't collapse.]]> 2018-01-11 05:27:32 UTC https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220455678 How do the luminosities and lifetimes of star depend on their mass? anthony_sobeck https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220455714 Generally, larger stars burn more fuel (more surface area) and release more energy (light) compared to their smaller counterparts. This does not apply to non-main sequence stars.]]> 2018-01-11 05:28:07 UTC https://padlet.com/anthony_sobeck/oxeicqq0e1l4/wish/220455714
