KRC for Exoplanets

Revision as of 14:30, 16 January 2019

A user can define the orbital parameters of any body rotating around any star. PORB generates the rotation matrix accordingly.

First, run PORB to create a structure that can be ingested to generate the orbital rotation matrix. The following arguments are needed:

e: Eccentricity (Default=0)

a: Semi-Major Axis in AU (Default=1)

i: Inclination of mean orbit to ecliptic in degrees (Default=0)

node: Longitude of the asceding node in degrees (Default=0)

per: Argument of perihelion in degrees (Default=0)

m: Mean Anomaly at epoch in degrees (Default=0)

rot_per: siderial rotation period in hours (Default=23.9345)

polera: Right Ascension of the pole in degrees (Default=0)

merid: Prime meridian at epoch in degrees (Default=0)

poledec: Declination of the pole in degrees (Default=0)

period: Sideral orbital period in Earth days (Default=365.256)

name: Body name (default ="None")

Then run generic_porb() with these arguments, for example:

tmp = generic_porb(e = 0, a = 1., i = 1.3, node = 100.4, peri = 293.9, m = 79.6, rot_per = 200., polera = 273.8, poledec = 0., merid = 7.7, period = 4332.5, name = "IdealJupiterTrojan")

Then run KRC using this new body as the "body":

out = krc( lat = 0., lon = 0, INERTIA = 20., ALBEDO =.05, LKofT = "F", body = tmp, bodytype = "minor")

This case above assumes the Sun as the central star. Any star can be defined by setting SOLCON (solar constant defined as the total stellar irradiance at 1AU in W/m^2. In the solar system, SOLCON ~ 1,361 W/m2.

out = krc( lat = 0., lon = 0, INERTIA = 20., ALBEDO =.05, LKofT = "F", body = tmp, bodytype = "minor", SOLCON = 2722.)

The case above assumes a start outputting twice as much energy as the Sun ("Super Sun").
