KWD.autogen
The exponent for the mass loss rate as defined in the KWD model, m_dot(r) = F(r) ** alpha = T(r) ** (4 * alpha). F is the local luminous flux and T is the local temperature at a radius R. A value of 0 sets a uniform mass loss rate.
Type: Double
Values: Greater than or equal to 0

Multiple of the local sound speed at the base of the wind, this results in the initial velocity of the wind being able to be greater or less than the local sound speed.
Type: Double
Unit: Sound speed at wind base
Values: Greater than 0

The size of the acceleration length scale for a disk wind described by the KWD model.
Type: Double

The radius at which the disk wind terminates, in units of central object radii. This has to be greater than rmin.
Type: Double
Unit: :ref:`Central_object.radius`
Values: Greater than :ref:`KWD.rmin`

Sets the length scale over which the accleration to v_inf is accomplished. It is the value of the exponent beta for the Caster & Lamers equation of a stellar wind, v(r) = v_0 + (v_inf - v_0) * (1 - R_s/r) ** beta.
Type: Double
Values: Greater than 0

The radius at which the disk wind begins, in units of central object radii.
Type: Double

The ratio d/d_min is used to describe the degree of geometric collimation of the disk wind in the KWD model. However, d (the distance to the focal point in central object radii) is used as this provides a more natural parameter.
Type: Double
Unit: :ref:`Central_object.radius`
Values: Greater than 0

The velocity at large distances of a steller wind described by the KWD model, in units of escape velocity. Described in terms of Castor & Lamers equation, v(r) = v_0 + (v_inf - v_0) * (1 - R_s/r) ** beta.
Type: Double
Unit: Escape velocity
Values: Greater than 0
