... 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. ...

Next: The Supernovae Rates Up: No Title Previous: Gravitational wave background from . In this Section we present the results of the Scenario Machine simulation of supernova explosion (SN) rates in the Galaxy for various types of supernovae and apply them for estimating the - dependence for the SN in the Universe (see JЖrgensen et al. 1995[ 80 ]). The Supernovae Rates . Dependence for the Supernova Explosions . for Supernova Explosions . Results and Discussion . ...

... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ... For all possible pairs the probability of trajectory approach at small distances for the epoch, corresponding to the age of the younger pulsar have been evaluated. ... Pulsars J0543+2329 and J0528+2200. ...

Observations of the local Universe clearly demonstrate that very active star formation phases (starbursts) are often associated with interacting and merging galaxies and that in these systems much of the short wavelength emission is absorbed by dust and re-emitted in the IR. ...

Next: M.E. Bailey, Director Up: Research Previous: C.S. Jeffery, Research Astronomer Contents . Dr Michael Smith has focused mainly on the earliest stages of stellar evolution: the processes leading to star formation from an initially unstable, collapsing cloud of gas, and the energetic outflows -- jets and winds -- associated with the formation and early evolution of protostars and pre-main-sequence stellar objects. ... Spectacular jets of molecules, however, betray its presence. ...

... For NGC3516 we find that the X­ray warm absorption and the broad UV associated absorption features can be produced by the same absorbing material. ... Is it also true for NGC3516? ... 1996). ... Here we argue that the XUV absorption picture is consis­ tent with the presence of a highly ionized X­ray absorber and the current non­ detection of CIV and NV broad absorption lines (see Fig. ...
