CONAN.utils.tdur_to_rho(Tdur, b, Rp, P, e=0, w=90, tra_occ='tra')#

convert transit duration to stellar density in g/cm^3 https://doi.org/10.1093/mnras/stu318

Parameters:

  • Tdur (float, ufloat, array-like;) – The transit duration in days.

  • 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)

Returns:

rho – The stellar density in g/cm^3.

Return type:

array-like;
