CONAN.utils.EV_amplitude(qm: float | UFloat, aR: float | UFloat, inc_rad: float | UFloat, alpha1: float | UFloat, alpha2: float | UFloat)#

calculate theoretical ampltiude of ellipsodial variation eqn 9 and 11 of Esteves2013 https://doi.org/10.1088/0004-637X/772/1/51

Parameters:

  • qm (float,UFloat) – planet-to-star mass ratio

  • aR (float,UFloat) – scaled semi-major axis

  • inc_rad (float,UFloat) – inclination of the orbit in radians

  • alpha1 (float,UFloat) – ellipsoidal variation coefficient 1 used in the fractional constants f1 and f2

  • alpha2 (float,UFloat) – ellipsoidal variation coefficient 2 used in the main amplitude Aev

Returns:

Amplitudes – f1 : float, UFloat. fractional constant f1 Aev : float, UFloat. main amplitude of ellipsoidal variation in ppm

Return type:
