... 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. ...

... Standard Commands . ... TwistedActor.Actor is core code for writing an actor: an instrument control computer (ICC) or hub-based script that does something useful. This manual describes the standard commands and keywords that any actor based on TwistedActor.Actor will support. All actors based on TwistedActor typically support the following standard commands (plus additional device-specific commands documented in that actor's manual). ... Connect one or more devices (if not already connected). ...

. To append the standard output from a command to a file use two >> (greater than) symbols followed by the name of the file. If the file does not exist it is created. For example: cat part1 > chapt2 cat part2 >> chapt2 . This creates a file called chapt2 with the same contents as part1 . It then reads the contents of part2 and appends them to the file chapt2 . The file chapt2 now contains the data from part1 followed by the data from part2 .

... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

... Using UNIX System Calls and Library Functions . ... To use system calls and library functions in a C program we simply call the appropriate C function. Examples of standard library functions we have met include the higher level I/O functions -- fprintf() , malloc() .. ...
