... 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. ...

... Axis Controllers . ... Guider Image Controller Commands . ... Multiple controllers (except the guide image controller) may co-exist in one box and share one serial interface. ... Some of these rules only apply to commands that the TCC may execute, and so may be relaxed for engineering commands. ... The command echo should be in the same case as the received command. ... Note: The Galil motion controllers output a semicolon for each command that appears on a line (as part of the command echo). ...

... 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() .. ... For most system calls and library functions we have to include an appropriate header file. e.g. stdio.h, math.h . ... Information on nearly all system calls and library functions is available in manual pages. ...

... Tracking stations will be selected in accordance with the schedule issued daily by the General Operative Control Group (GOCG) in Lavochkin Association with the gaps in operations during spacecraft contact with the control stations (CS). ... Communication frequencies (carrier): high data rate information transmission downlink from the SRT ­ 15.000 GHz; uplink synchronization ­ 7.2075 GHz; downlink synchronization ­ 8.400 GHz. ...

... 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. ...
