Stars on the main sequence fuse hydrogen to helium in their cores. Since low-mass stars process their hydrogen relatively slowly, they stay on the main sequence for a long time. But what happens when they finally use up all the hydrogen in their cores?

fter a few million years the low mass star begins to fuse helium into hydrogen. When this happens the collapse is ended because the fusion raises the pressure inside the star. During this period the star is commonly referred to as a Protostar.; ... Low Mass Stars Title...

Star formation - Wikipedia, the free encyclopedia
Star formation is the process by which dense parts of molecular clouds collapse into a ball of plasma to form a star. As a branch of astronomy star formation includes the study of the interstellar me...

Subsequently, these low mass stars can be used as tracers of the disk metallicity gradients up to large distances. ... The angular speed at 1 AU is close to 1 degree per day, for a 1 Solar mass system. For low-mass stars, stellar radius and mass closely follow ([Baraffe et al.1995]), so that the angle subtended is...

Evolution of Low Mass Stars ... The evolution of low mass stars is similar to the evolution of high mass stars. The primary difference is in how far an individual star moves along the nuclear burning chain. This then leads to differences in the ways in which the stars end their lives.

The position of the protostar and the main sequence star on the HR diagram will also vary with the mass of the star. Massive stars will be along the upper left portions of the main sequence while low mass stars fall upon the lower right portion.

If a Star has a mass of less then 4 stellar masses, then the Star will become a Red Giant when it has used most of its Hydrogen in the process of nuclear fusion. This Red Giant will lose its mass by gently ejecting its outer layers to form a Planetary Nebula. ... High Mass Stars;

However, radiative hydrodynamic models of protoplanetary disks around low-mass stars (of 0.1 to 1 solar mass) show that Jupiter-like planets should form at distances (approximately 4 to 5 AU) that are only weakly dependent on the stellar mass.

A very basic one is whether low-mass stars form at all in such environments. And if so, do they form together with the most massive stars in a starburst event or do they form at different times, before or after or perhaps on different timescales?
