Procedural Atmosphere for exoplanet - pseudorealistic composition, pressure etc

I think you balanced your equation wrong, try this: Tf₂ = 1 / ((1/T₁) - (ln(P₁/P₂) / (-ΔHfus / R)))

Characteristics of a moon harboring huge flying creatures?

The best environment for flying creatures in our solar system may be in dense enough layers of the atmospheres of the giant planets in our solar system. If you go deep enough into the atmosphere of a ...

Is it possible for a super Earth to have this specific atmospheric composition?

Clearly, the planet has lots of life on it, which includes life that produces oxygen as a waste product. On Earth, that's mostly done by plants, but a different planet might be differently arranged. ...

Is that an elliptical orbit gas giant?

As you orbit around the gas giant while the gas giant gets closer to the central star, that will give two surely visible effects: the apparent size of the star in the sky will increase, and more ...

Is that an elliptical orbit gas giant?

Can we lose a little atmosphere to solve the problem? We'd need @HDE226868 to confirm this, but might it not be possible that an orbit sufficiently close to the star might leave a trail of gaseous ...

Is that an elliptical orbit gas giant?

This gives me a nice opportunity to talk about one of my favorite subjects: Uranus. You see Uranus may be relatively small (it's not quite as big as Jupiter), but due to its size category it can ...

How small can you make a planet or moon and still have dust devils on its surface?

Wild idea, but lets assume the planet is negatively charged. Now there is a world - like a gas giant nearby, throwing radiation and accelerated particles in large . Now there being no atmosphere the ...

How small can you make a planet or moon and still have dust devils on its surface?

The ability of a world to retain atmosphere doesn't depend on its surface gravity but on its escape velocity. In order for a world to retain atmosphere for along time, the escape velocity has to be ...

How small can you make a planet or moon and still have dust devils on its surface?

As long as it can have an appreciable atmosphere, as small as you want. Did you know that Mars has dust devils? In fact, they have posed an issue for rovers - if a dust devil throws dust onto a rover'...
