pint.derived_quantities.pulsar_B_lightcyl(f: Unit('Hz'), fdot: Unit('Hz / s'))

Compute pulsar magnetic field at the light cylinder

Return the estimated pulsar magnetic field strength at the light cylinder given the spin frequency and frequency derivative.

Parameters:

• f (astropy.units.Quantity) – pulsar frequency

• fdot (astropy.units.Quantity) – frequency derivative \(\dot f\)

Returns:

Blc – pulsar dipole magnetic field at the light cylinder in u.G

Return type:

astropy.units.Quantity

Raises:

• astropy.units.UnitsError – If the input data are not appropriate quantities

• TypeError – If the input data are not quantities

Notes

Calculates \(B_{LC} = 2.9\times 10^8\,{\rm G} P^{-5/2} \dot P^{1/2}\)
