CONAN.utils.k_to_Mp(k, P, Ms, i, e, Mp_unit='star')#

Compute the mass of a planet from the rv semi amplitude following https://iopscience.iop.org/article/10.1086/529429/pdf

Parameters:

  • k (float, ufloat, array-like;) – The RV semi-amplitude in m/s.

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

  • Ms (float, ufloat, array-like;) – The mass of the star in solar masses.

  • i (float, ufloat, array-like;) – The inclination of the orbit in degrees.

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

  • Mp_unit (str;) – The unit of the mass of the planet [“star”,”jup”] Default is “star” which returns the mass in units of the mass of the star.

Returns:

Mp – The mass of the planet in Jupiter masses.

Return type:

array-like;
