WebbSteven N. Shore, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.B Induced Star Formation. Should the star formation begin within a molecular cloud, … 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 astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular … Visa mer 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 medium consists of 10 to 10 particles per cm … Visa mer 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 … Visa mer 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, the collapsing cloud will eventually become opaque to its own radiation, and the … Visa mer 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 … Visa mer • Accretion – Accumulation of particles into a massive object by gravitationally attracting more matter • Champagne flow model Visa mer

Webb…the processes that operate during stellar evolution enable estimates to be made of the ages of stars. There is, for example, a clear tendency for very old stars to have smaller quantities of elements heavier than helium than do younger stars. This suggests that the Galaxy originally contained little of… Read More WebbNew astronomical facilities planned for development during the 1980's could lead to significant advances in our understanding of the star formation process.

As it forms, the molecular cloud condenses and … Webb1 sep. 1990 · There are three major sources responsible for the synthesis of the elements: comological nucleosynthesis in the big bang, nucleosynthesis during stellar evolution, and nucleosynthesis in the interstellar medium induced by cosmic rays; this presentation focusses on the second of these processes. sixty toddlers
