WebMain sequence O stars have convective cores because they fuse hydrogen in the proton-proton chain. true One of the factors that a large molecular cloud must overcome in order … WebA star is formed when it is hot enough for the hydrogen nuclei to fuse together to make helium. The fusion process releases energy, which keeps the core of the star hot. Main …
WebMay 7, 2015 · As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by … WebJul 8, 2024 · How Do Stars Produce Energy? Once the star gathers enough mass, pressure from gravity will cause the core to heat up. Stars begin their lives by fusing hydrogen …
A normal star forms from a clump of dust and gas in a stellar nursery. Over hundreds of thousands of years, the clump gains mass, starts to spin, and heats up. When the clump's core heats up to millions of degrees, nuclear fusion starts. This process occurs when two protons, the nuclei of hydrogen atoms, merge to … See more The universe’s stars range in brightness, size, color, and behavior. Some types change into others very quickly, while others stay relatively unchanged over trillions of years. See more When a main sequence star less than eight times the Sun’s mass runs out of hydrogen in its core, it starts to collapse because the energy produced by fusion is the only force fighting … See more Neutron stars are stellar remnants that pack more mass than the Sun into a sphere about as wide as New York City’s Manhattan Island is … See more After a red giant has shed all its atmosphere, only the core remains. Scientists call this kind of stellar remnant a white dwarf. A white dwarf is usually Earth-size but hundreds of thousands of times more massive. … See more
