... Energy . ... The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much, much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

Amanda Karakas One of the most important research fields in astrophysics is the study of the origin of the elements. ... Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...

When you enter a command it invokes a program. While this program is running it is called a process . It is important to grasp that although there is only one copy of a program held in the file system , any number of processes can be invoked which run this program. When the operating system is started after a boot , a single process is started. ... Any processes that are started from within your shell - such as entering a command - are the children of this process. ...
