Detailed Description

Base class for stars *** DEPRECATED : use class Star instead ***.

()

An Etoile is constructed upon (i) a mapping (derived class of Map ), the center of which defines the center of the star, and (ii) an equation of state (derived class of Eos ). It contains tensor fields (class Tenseur ) which describle the hydrodynamical quantities as well as the gravitational field (spacetime metric).

According to the 3+1 formalism, the spacetime metric is written

\[ \label{eetoilemetrique} ds^2 = - (N^2 - N_i N^i) dt^2 - 2 N_i \, dt\, dx^i + A^2 \, {\tilde h}_{ij} \, dx^i dx^j \]

where ${\tilde h}_{ij}$ is a 3-metric, the exact form of which is specified in the derived classes of Etoile . The base class Etoile by itself provides only storage for the lapse function N (member nnn ), the shift vector $N^i$ (member shift ) and the conformal factor $A^2$ (member a_car ).

The 3+1 formalism introduces two kinds of priviledged observers: the fluid comoving observer and the Eulerian observer, whose 4-velocity is the unit future directed normal to the t = const hypersurfaces. The hydrodynamical quantities measured by the fluid observer correspond to the members ent , nbar , ener , and press . The hydrodynamical quantities measured by the Eulerian observer correspond to the members ener_euler , s_euler , gam_euler , and u_euler .

A star of class Etoile can be either relativistic or Newtonian, depending on the boolean indicator relativistic . For a Newtonian star, the metric coefficients N and A are set to 1, and $N^i$ is set to zero; the only relevant gravitational quantity in this case is logn_auto which represents the (regular part of) the Newtonian gravitational potential generated by the star.

Description of the stellar surface: returns a 2-D Tbl containing the values of the radial coordinate $\xi$ on the surface at the collocation points in $(\theta', \phi')$.

The stellar surface is defined as the location where the enthalpy (member ent ) vanishes.
