... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... 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. ...

Dogiel (I.E.Tamm Theoretical Physics Division, P.N.Lebedev Physical Institute) . ... Up to now no model has been able to explain the physical origin of this emission. Even the most plausible mechanism of bremsstrahlung radiation requires an energy output in emitting particles higher than the luminosity provided by known Galactic sources. ...

... The C III] multiplet near 1908? has a transition at 1909.6? completely forbidden in C, but allowed as a result of the non-zero nuclear spin of C. The C III] line was observed with the GHRS and Echelle-B and a positive detection of the C line was made in the Galactic C-rich PN NGC 3918; a marginal detection of the C line was made in SMC N2, which is also C rich. ... The derived C/ C ratio is 15 3. For SMC N2 the C line is much weaker and a 2 detection was made: the C/ C ratio was measured as 21. ...

Abstract . A first-generation CMOS Charged Particle Spectrometer chip [1] was designed at JPL for flight on the STRV-2 spacecraft. These devices will collect electron and proton spectra in low Earth orbit as part of an experiment to demonstrate Active Pixel Sensor (APS) technology in space. This paper presents the results of total dose testing on these chips and, where possible, attempts to extend the results to other Active Pixel Sensors. ...
