How do stars form in such a dense environment
WebType O and B stars are very hot: surface temperature greater than 10,000 K. Peak wavelength for 10,000 K is in the UV part of the spectrum. Light radiated from these stars is very energetic and can easily ionize any … WebStars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure …

WebAnswer : The significant dynamical processes involved in star formation are turbulence , magnetic fields , and self - gravity . Turbulence contribute in both creating overdensities … WebA molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit absorption nebulae, the formation of molecules (most commonly molecular hydrogen, H 2), and the formation of H II regions.This is in contrast to other areas of the interstellar medium that contain …
WebDec 7, 2010 · Massive stars are powerful sources of radiation, stellar winds, and supernova explosions. The radiative and mechanical energies injected by massive stars into the … Stars of different masses are thought to form by slightly different mechanisms. The theory of low-mass star formation, which is well-supported by observation, suggests that low-mass stars form by the gravitational collapse of rotating density enhancements within molecular clouds. As described above, the … See more Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars. As a branch of See more Key elements of star formation are only available by observing in wavelengths other than the optical. The protostellar stage of stellar existence is almost invariably hidden away deep inside dense clouds of gas and dust left over from the GMC. Often, these star … See more Interstellar clouds A spiral galaxy like the Milky Way contains stars, stellar remnants, and a diffuse interstellar medium (ISM) of gas and dust. The interstellar … See more A protostellar cloud will continue to collapse as long as the gravitational binding energy can be eliminated. This excess energy is primarily lost through radiation. However, … See more • Accretion – Accumulation of particles into a massive object by gravitationally attracting more matter • Champagne flow model See more
