1. Astronomy HyperText Book: Stellar Evolution
... 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. ...

5. Starburst and Galaxy Evolution Introduction
Stars are the fundamental building blocks of galaxies. ... Comparison between observations and models of evolving stellar populations helps understand the star formation process, triggering mechanisms, influence of the environment, the chemical history, and processes in the interstellar gas. Our research concentrates on galaxies with active current star formation. Many of these objects show signatures of violent high-mass star formation, a phenomenon often called `starburst'. ...

12. The ASC Pipeline: Concept to Prototype
... Discusses the role of a pipeline in the AXAF Science Center Data System. Due to the complexity of the application, a prototyping effort was initiated to evaluate the risks involved with portability, open architecture, error handling/recovery, and distributed processing. Processes in the pipeline are initiated and monitored by a process control application developed using Perl. ... During that time, a Process Control application was developed to allow us to assess the risk factors. ...
