Proxima Centauri and the Sun are both main-sequence stars, but Proxima Centauri is a red dwarf and the Sun is a yellow dwarf. Based on the information you charted, compare the characteristics of red dwarf stars and yellow dwarf stars, please help

red dwarf stars have a very low mass while yellow dwarf stars have a very high mass

Explanation:

the reason for this is because red dwarf stars burn at a cooler temperture and are smaller. the oppisite for yelow stars

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
