Running KRC for Non-Tidally Locked Airless Bodies

KRC can predict surface and subsurface temperatures for asteroids, comets, or any non-tidally locked body.

The ability to work with tidally locked body will be developed in the future, but is not yet available.

• Define the body type

Planets and Pluto : No need to define bodytype

Mercury(!!!), Venus, Earth, Mars, Jupiter(!!!), Saturn(!!!), Uranus(!!!), Neptune(!!!), and Pluto can be modeled. (!!!): tidally locked or no rocky surface

Make sure to adjust the atmospheric parameters !

Over 3,200 comets are supported

Comets : bodytype="comet"

A list of comets currently supported is provided here

Over 390,000 comets are supported

Make sure to turn off the atmosphere by setting PTOTAL=0.

Asteroids : bodytype="minor"

A list of asteroids currently supported is provided here

Over 3200 comets are supported

Make sure to turn off the atmosphere by setting PTOTAL=0.

TAURAT: Ratio of thermal to visible opacity of dust

DUSTA: Single scattering albedo of dust

ARC2: Henyey-Greenstein asymmetry factor

KRC assumes broadband atmospheric opacities, but the default values are given a specific wavelengths.

1. VIS/9μm dust opacity ratio is ~2:1 (M. Smith personal communication);

2. 9μm to broadband TIR ratio is 2.5:1 (ratio of maximum and average values of the dust opacity spectrum from Bandfield and Smith, [2003], Figure 3);
