Constructor & Destructor Documentation

GRBShell::GRBShell (  double    gamma, double    mass, double    thickness, double    radius, double    distance = 0.0, std::string    type = "jet" )

Creation of a new shell. Parameters: gamma  is the The Lorentz factor of the shell. mass  is the mass of the shell is computed as: . thickness  is in cm. radius  of the jet. In cm. distance  of the Shell to the central engine. In cm. type  indicates the type of geometry. If "jet" the emission of shells from the central engine is beamed. Else is isotropic.

Member Function Documentation

double GRBShell::beta (  const double    gamma )

Return values: beta  =

void GRBShell::evolve (  double    time )

Time evolution of the shell. This method can be used by GRBengine to evolve the shells prior to checking for new shocks. Radius of the shell is moved forward by Parameters: time  timestep of evolution

double GRBShell::getVolCom (    )  [inline]

Returns the comoving volume (in ). The comoving volume is defined as for isotropic shells, for jet shells.
