View Full Version : Models for planetary habitability: are they out there?

Are the models out there, not ET; that's a question, quagmire, and bait for censorious quasi-skeptics.

What I'm asking about is whether there are computer programs, preferably suitable for classroom use, that can take a few inputs, like mass, stellar luminosity and temperature, basic orbital parameters, and atmosphere and generate something like temp vs latitude, or at least mean surface temperature and a vertical lapse rate, magnetic field strength, and how long the planet could have plate tectonics.

Check out the Planetary Habitability Laboratory (http://phl.upr.edu/) in Puerto Rico (Aricebo), they have some papers and online calculators there that I've referenced for planet-building, and additional links. Here's a useful page of calculators (http://phl.upr.edu/projects/habitable-exoplanets-catalog/calculators) there.

Here's a site (http://www.calctool.org/CALC/phys/astronomy) with various calculators that might be useful.

Here's a site that calculates synodic period (http://www.1728.org/synodic.htm) for any two orbital periods, useful for determining conjunctions and oppositions, and thus launch windows.

Here's an old site (http://www.world-builders.org/) for an online class that taught how to build a planet, based on 90s data. They have some useful data that you may or may not have thought of, but it's mostly old hat. However it does contain some tables on solar mass, luminosity, and other measurements I didn't find elsewhere.

Thank you.
