Stars, like people, have life cycles -- they are born, pass through several phases, ... Stars that have similar masses may not be similar in size -- that is, they may have different densities. Density is the amount of mass per unit of volume. ... When the temperature and pressure in the protostar's core become high enough,

A Star's Life: We head now on a journey through the life of a star. Those of you who have already read the section on The Beginnings already know a little about how stars start their formation. For those who haven't, don't worry, we are about to repeat it here for you as well.

18.1. End of Main-Sequence Life ... This event is determined by a star's main-sequence mass. To discuss this point, we must divide stars into two groups for their approach to helium burning and subsequent evolution: low-mass stars, whose masses are less than about 2M., and high-mass stars, whose masses are greater than 2M..
