CONAN.utils.rho_to_tdur(rho, b, Rp, P, e=0, w=90, tra_occ='tra', total=True)#

convert stellar density to transit duration in days https://doi.org/10.1093/mnras/stu318

Parameters:

  • rho (float, ufloat, array-like;) – The density of the star in g/cm^3.

  • b (float, ufloat, array-like;) – The impact parameter.

  • Rp (float, ufloat, array-like;) – planet-to-star radius ratio.

  • P (float, ufloat, array-like;) – The period of the planet in days.

  • e (float, ufloat, array-like;) – The eccentricity of the orbit.

  • w (float, ufloat, array-like;) – The argument of periastron in degrees.

  • tra_occ (str;) – select duration of transit (tra) or occultation (occ)

  • total (bool;) – select total duration T14 (True) or full duration T23 (False)

Returns:

Tdur – The transit duration in days.

Return type:

array-like;
