Homogeneous ModelsΒΆ
Homogeneous models represent uniform-density stars in hydrostatic equilibrium; they are equivalent to polytropes with index \(n=0\). Because their structure can be calculated analytically, GYRE creates them on-the-fly without the need to read from an external file.
To use a homogeneous model with GYRE, set the model_type
parameter in the &model
namelist group to 'HOM'
, and
set the Gamma_1
, n
, s
and
grid_type
parameters to suitable values (see the
Stellar Model Parameters section for more details).
