Struct HernquistIC

pub struct HernquistIC {
    pub mass: Decimal,
    pub scale_radius: Decimal,
    pub g: Decimal,
    /* private fields */
}

Expand description

Hernquist (1990) cuspy halo model.

Density profile rho proportional to 1/(r (r+a)^3), yielding a central r^{-1} cusp more realistic than Plummer for galaxy halos. The DF is available in closed form (Hernquist 1990, eq. 17).

Fields§

§mass: Decimal

Total mass of the system.

§scale_radius: Decimal

Hernquist scale radius a.

§g: Decimal

Gravitational constant G.

Implementations§

Source §

impl HernquistIC

Source

Create a Hernquist IC from f64 parameters.

Source

pub fn new_decimal(mass: Decimal, scale_radius: Decimal, g: Decimal) -> Self
