fiesta.properties.calc_total_gravitational_potential_energy(mass, rho, unit=Unit('erg'))[source]#

Calculates gravitational potential energy using \(E_\mathrm{grav} = \frac{3}{5}\frac{GM^2}{R}\).

Parameters:

  • mass (Quantity) – Mass \(m\).

  • rho (Quantity) – Density \(\rho\).

  • unit (Unit, optional) – Unit to output the result in. Default value is u.erg.

Returns:

Egrav (numpy.ndarray) – Gravitational potential energy \(E_\mathrm{grav}\).
