... 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. ...

... This article describes the AXAF aspect determination pipeline and its components, and highlights a procedure for determining centroids-a crucial step in deriving the post-facto aspect solution. ... The Ground Aspect Determination System (GADS) pipeline is a collection of tools which process aspect telemetry and generate aspect data products. ... Using a subset of ACA pixel data from the Aspect Interval, we identify poorly-fitting PSFs and find spoiler stars in star and fiducial light images. ...

Electron Bombarded, Back-Illuminated CCD Sensors . ... EBCCD PERFORMANCE: EBS Gain . ... To the first order, the signal gain in the EBCCD is proportional to the kinetic energy of the photoelectrons prior to their impinging on the CCD back surface. ... To obtain EBS gain in the active material, it is necessary for the photoelectron to enter the pixel from the back surface of the CCD -- away from the gate structures that dissipate the electron energy. ... The EBCCD EBS gain was tested using two methods. ...

... user-defined data file formats . ... better integration with a user's analysis routines To add such functionality to SAOimage, we developed the XPA Messaging System that allows X programs to define points of public access through which data and commands can be exchanged with external programs. ... We have utilized XPA to develop "SAOimage: The Next Generation" (SAOtng), an extensible image display service that can cooperate with other processes and programs. ... SAOtng help pages . ...

... First the task demos (``de-mosaic'') is used to break the model produced by mosmem into models for individual pointings. ... Task selfcal takes all the models simultaneously and then, for each visibility in the input visibility dataset, it computes a model visibility using the model with the same pointing centre. ... DEMOS . ... There are, however, multiple input models (produced by demos ) corresponding to each of the pointings to be used in the self-calibration. ... Models produced by demos . ...
