What physical state defines a star during its main sequence phase?
What is the approximate mathematical relationship governing luminosity (L) based on a main-sequence star's mass (M)?
If luminosity is proportional to M^3.5, how does the main sequence lifespan ( au_MS) scale with mass (M)?
Which fusion process primarily powers stars significantly more massive than about 1.5 solar masses?
What causes the extremely high luminosity and rapid fuel consumption in massive stars?
What internal structure feature allows massive stars to utilize a larger fraction of their total hydrogen supply?
What mechanism allows very low-mass red dwarfs (below 0.4 M_sun) to achieve lifespans potentially exceeding the current age of the universe?
What element's formation in the core signals the end of energy generation for a massive star, triggering collapse?
