Nebula is a cloud of gas (hydrogen) and dust in space. Life for Nebula was very cold. Nebula's temperature was 100 degrees celsius. I want nebula to be low mass.
Protostar is a large mass that forms by contractions out of the gas of a giant molecular cloud in the interstellar medium. Life for a protostar was 10-20 kelvins, the most at radiation. I want protostar to be low mass.
Main Sequence star are stars that are fusing hydrogen atoms to form helium atoms in their cores. I want main sequence stars to be low mass. Life like for main sequence stars were they were go from a star to a red giant.
A luminous giant star of low or intermediate mass, in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous. I want a red giant to be a low mass.
A kind of emission nebula consisting of an expanding glowing shell of ionized gas ejected from old red giant stars late in their lives. A ring shaped nebula formed by an expanding shell of gas around aging star. I want a planetary nebula to be low mass.
A small dense star that typically the size of a planet. A white dwarf is formed when a low-mass has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula. I want a white dwarf to be a low mass.
A black dwarf is formed when a white dwarf tat has cooled down to the temperature of the cosmic microwave background, and so is invisible. Unlike red dwarfs, brown dwarfs, and white dwarfs, black dwarfs are entirely hypothetical. I want a black dwarf to be low mass.
An aging giant star which has consumed its core's supply of hydrogen fuel. These shells then expand, and the now cooler star takes on a red color and they are the largest known stars. I want a red supergiant to be low mass.
A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. Also basically its the explosion of a star. I want a supernova to low mass.
