Why is the current stellar population overwhelmingly composed of low-mass stars?
Answer
Their main sequence phase is so long that they represent the majority still shining today
Low-mass stars have lifespans extending into the trillions of years, meaning they are still plodding along their main sequence schedule, while the main sequence phase for massive stars is so brief they represent a minuscule fraction of the observable population.
