Spent the past several hours trying to make a "simple" model for what kinds of gasses can exist in a planetary atmosphere. This only models Jeans escape; solar wind erosion is a lot more complicated and isn't modeled, so just because a planet could retain water doesn't mean that it does (Venus, Mars).

Some things I learned:

• Mass has a much stronger effect on atmospheric retention than insolation (temperature)
• It's pretty rare for a planet with less than 1e23kg of mass to have a significant atmosphere
• A planet doesn't need to be much more massive than Earth to enter gas giant territory
• I had to cheese this model a bit to allow Titan to retain methane, despite the fact that it does IRL
