It is believed that white dwarfs began life as low-mass or medium-mass stars. As the star ages, it begins to collapse—become a “dwarf”—because it no longer produces sufficient radiant heat to counteract the contracting force of its gravity.

Red Giant Branch – helium ash core compresses – increased hydrogen shell burning. First Dredge Up – expanding atmosphere cools star – stirs carbon, nitrogen and oxygen upward – star heats up. WebThe locus of stellar masses on the horizontal branch is determined by helium core mass. The RR Lyr stars range in spectral type from A3 to A6 and have absolute magnitudes of about 0.m5, about 10 2 L⊙. They are low-mass stars, 0.5 to 0.7 M ⊙.

Scientists expect it will remain one for another 5 billion years before becoming a red giant. Credit: NASA's Scientific Visualization Studio/SDO. The universe’s stars range in brightness, size, color, and behavior. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain. They usually have a convection zone, and the activity of the convection zone determines if the star has activity similar to the sunspotcycle on our Sun. Some small stars have very deep convection zones. … Meer weergeven Size comparison of the Sun as a red giant star and the Sun as a main sequence star.
