Planetary RV signal

A Keplerian model for non-interacting planets. The effect of each planet on the radial velocity of the host star are modelled as non-interacting Keplerians.

Model definition and requirements

• model name: radial_velocities

• required common objects : planets , star

Keywords

There are no keywords defined for this model, all the relevant information are inherited from the planet common model

Examples

Minimal configuration for a model

models:
  radial_velocities:
    planets:
     - b

Tip

Planets are automatically assigned to the star model when there is only one stellar object specified in the model

Model parameters

The following parameters will be inherited from the common model (column Common?: common) or a different value will be assigned for each dataset (column Common?: dataset)

Name	Parameter	Common?	Definition	Notes
P	orbital period of the planet	common	planets
K	Radial velocity semiamplitude	common	planets
mean_long	mean longitude of the orbit, assuming \(\Omega=0\)	common	planets	(1)
Tc	Time of inferior conjunction	common	planets	(2)
e	eccentricity of the orbit	common	planets	(3)
omega	argument of pericenter of the planet \(\omega_p\)	common	planets	(3)
e_coso	\( e \cos{\omega}\) in Ford 2006 parametrization	common	planets	(4)
e_sino	\( e \sin{\omega}\) in Ford 2006 parametrization	common	planets	(4)
sre_coso	\( \sqrt{e} \cos{\omega}\) in Eastman 2013 parametrization	common	planets	(5)
sre_sino	\( \sqrt{e} \sin{\omega}\) in Eastman 2013 parametrization	common	planets	(5)

Notes:

1. replaced by Tc when use_time_inferior_conjunction: True

2. use_time_inferior_conjunction: True parametrization only

3. Standard parametrization only

4. Ford2006 parametrization only

5. Eastman2013 parametrization only
