This star class only refers to new low-mass stars. Where do all stars begin? All stars begin life inside of a stellar nebula. An example of this is the Pillars of Creation. This nebula currently houses over 7000 stars and many more are forming. What are three things that a star is ...
All stars begin life inside of a stellar nebula. An example of this is the Pillars of Creation. This nebula currently houses over 7000 stars and many more are forming. What are three things that a star is made of? Stars are comprised primarily of hydrogen and helium. They will also conta...
A random multiplicative star forming process would not only include a temporal sequence of fragmentation steps but would also incorporate simultaneous influences which represent the initial conditions for the onset of the fragmentation process. (Auth.) 关键词: Star Formation:Models 被引量: 2 年份:...
feedback- the process in which part of the output of a system is returned to its input in order to regulate its further output filtration- the process whereby fluids pass through a filter or a filtering medium flocculation- the process of flocculating; forming woolly cloudlike aggregations ...

"We dynamically observed that dense cores in molecular clouds collapse and contract under gravity, eventually forming primitive stars, known as protostars," said Xu Fengwei, first author of the paper at Peking University. A large number of protostars with gravitational interaction then form clusters...
The final mass of the first star is fixed when mass accretion to a protostar ceases. We report our recent 2-dimensional radiation-hydrodynamic simulations of the mass accretion process to the primordial protostar. The protostellar evolution is also simultaneously calculated by solving the stellar ...
A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre...

A process for preparing silicon carbide by carbothermal reduction is disclosed. This process involves rapidly heating a particulate reactive mixture of a silica source and a carbon source to form a product which shows improved uniformity of crystal size. The product of this process can be used to...
