... 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. ...

... overview of pyQC . ... output used by . ... All pyQC scripts and modules share a similar structure. Python offers to group functions, classes, etc. into modules which can be imported by different scripts. ... In order to avoid confusion if names are used by different (especially external) modules, the QC scripts use the 'from' statement only for pyQC modules, i.e.: . ... For other modules, the simple 'import' statement is used: . ... Python modules are also used for keeping script configuration. ...

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms.
