How did stars form
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud … Ver mais A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Our Sun will stay in this mature phase (on the main sequence as … Ver mais In general, the larger a star, the shorter its life, although all but the most massive stars live for billions of years.

WebAs a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products. It is closely related to planet formation, another branch of astronomy. WebNeutron stars form in the death throes of stars with masses of 10–20 M⊙. Such high-mass stars can form at any time. Theory suggests, though, that they are dominant in the early universe, a few hundred million years after the Big Bang, at which time they have a propensity to be born as binaries. 4 4. S.
