What type of star outputs the most radiation over the course of its lifetime?

>> No.9655609

>>9655604

Red dwarf probably.

According to the virial theorem, all stars output the same amount of radiation over their lifetime.

Wolf Rayet stars and I believe pulsars spew radiation like a fountain

Black holes.

>>9655612
I think the bigger ones probably put out more.

The largest ones. (By mass)
Stars turn mass into energy.
The mass you don't have you can't radiate away.

A star with ten times the mass of the Sun might live only one hundredth as long but, while it lasts, it's a thousand times as luminous.

The energy output of a single hypernova is about equal to the complete conversion of the mass of proxima centauri into energy, so I'm going to say no to that one. Especially considering stars don't achieve very high efficiency of conversion of mass into energy, less than a percent.

>>9655609
Only if relatively to its mass.

It's gotta be that one emitting Hawking radiation that turned him into a potato.

Stars burn fuel for energy, a star with 100x as much fuel as a red dwarf will life way less time but will convert much more fuel to energy.
