Web3 sep. 2013 · Yellow and red dwarf stars are normal stars - they burn hydrogen in their cores and live on the main sequence of stellar lifetimes. Red dwarfs are smaller than our sun, only getting up to 50% the size of our sun. As a result, their surfaces are cooler, hence the colour shift towards the red. They don’t consume their hydrogen as quickly as our ... Web24 jul. 2024 · Yellow dwarf stars are not true dwarf stars, at least not in the sense that red or white dwarf stars are dwarfs.
