# Definition Sets
1late stage in the life cycle of a comparatively low-mass main sequence star; formed when its core depletes its helium and its outer layers escape into space, leaving behind a hot, dense core13 sets
2a dim star that forms from a collapsed red giant11 sets
3late stage in the life cycle of a main sequence star in which its core uses up its helium and its outer layers escape into space, leaving behind a hot, dense core7 sets
4a faint star of enormous density5 sets
5late stage of an average star's life after fusion when core contracts and emits light due to its heat and the outer layers escape,4 sets
6small dense dead star, very hot due to its gravitational collapse, no fusion going on, made up of normal matter (electrons orbiting the atoms nucleus)4 sets
7a small, hot star near the end of its life; the leftover center of an old star4 sets
8small dense star4 sets
9the remaining hot core of a star after its outer layers have expanded and drifted out into space3 sets
10when small stars collapse as they die3 sets
11the remaining hot core of a star after its outer layers have expanded and drifted out into space.3 sets
12a very small dying star that gives off very little light3 sets
13a small, hot, dim star that is the leftover center of an old star3 sets
14stage in which a star has used up its helium and its outer layers escape into space, leaving behind a hot, dense core that contracts2 sets
15a star near the end of its life2 sets
16what will our sun become after a planetary nebula?2 sets
17a red giant at the end stage of its evolution will throw off mass and leave behind a very small (the size of the earth), very dense star in which no nuclear reactions take place. it is very hot but its small size gives it a very low luminosity.2 sets
18a low-mass stellar remnant that has exhausted all its thermonuclear fuel and contracted to a size roughly equal to the size of the earth2 sets
19the blue-white hot core of a star that is left behind after its outer layers have expanded and drifted out into space2 sets
20the smallest type of star2 sets
21an old very dense star2 sets
22still hot stored energy, about the size of earth2 sets
23a star after being a red giant and has lost most of its fuel1 set
24this is after the supernova and its just a big white ball.1 set
25when nebula disperses gravity causes the remaining matter to collapse inword1 set
26star that has exhausted most or all of its nuclear fuel and has collapsed1 set
27a hot white low mass star ending as a dark star1 set
28blue-white core of the star that is left cools and becomes a white dwarf1 set
29sun-like star that is near the end of its life; how our sun will end up some day1 set
30small, dense-> can be more massive than the sun, spoonful weighs several tons, atoms take up less space, electrons displaced inward,(degenrate matter), hot surface, cools to become black dwarf.1 set
31less massive red giant that is loosing strength, or final stages of cepheid1 set
32a dying star that has collapsed to the size of the earth and is slowly cooling off.1 set
33a ________________ is a star near the end of it's life.1 set
34the blue-white part of the star that is left behind and cools1 set
35giant star that has its outer layers leaving behind a hot, dense core that continues to contract under gravity1 set
36the small, dense but dim remains of a low or medium mass star.1 set
37the star cools and shrinks; it will eventually be only a few thousand miles in diameter! no nuclear reactions take place and the faint star radiates its heat into space1 set
38occurs when the star has used up all the energy and begins to cool further and condense1 set
39a late stage in a star's life cycle when its core runs out of fuel(helium) and its unstable outer layers escape into space, leaving the hot dense core.1 set
40a "tiny" collapsed star about the size of a planet near the end of its nuclear fusion period; white and very hot1 set
