Process:  - A star burns in space - Eventually it burns all its hydrogen - Becomes a red giant - Once the red giant burns itself out - The core of the star collapses - The gasses will start to disperse - Only the core is left - A white dwarf has been formed.  Perturbation hypothesis: suppose there is less hydrogen in the star happens, how will it affect there will be less gasses to disperse.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
