I would assume so, I have no problem altering the numbers for that, 46 day years are just not right, so if this gives me a reason to increase the lenth of the year then great. But not to the extreme maybe increase it to 148 days (4 times the origional lenth and so maybe giving us four seasons)
148 may be a little too long. Mercury, which is the closest orbit to our own sun (without being vaporized) orbits in 88 days. To account for a rather large eliptical orbit, what if we calculate the number of days for a planet orbiting in the 0 orbit (habitable zone of red dwarf) and one orbiting in the first orbit and then take the average?
Dazo said:The world is not volcanically active to any great extent nor is there much in the way of heavy industry(at least not yet there isn't as I still havn't decided on a concept as such) so if theres some other naturally occuring corrosive gas or compound then that should do. Incedentally what would you need for nitric acid to form, or hydroflouric acid(which is used for etching glass I think).
Nitric acid seems to be our best candidate so far. Hydrofluoric acid is more of a problem. Large quantities of the gas might be to volatile to exist for long . It also bonds readily with metals and other elements such as sodium...Does the planet have a large amount of ferrous metal? Alot of the florine might be bound up there or in calcium floride minerals.
Nitrogen dioxide on the other hand very common. How is this for a scenario. As the temperature increases, it cause a greater rate of evaporation from the oceans. The water molecules can react with the nitrogen dioxide to form nitric acid and one free oxygen.
Actually if the florine is reacting with the Sodium in the salt water of the ocean, we could end up with chlorine being present...whch is a strong oxidizer as well. If it bonds with Hydrogen to form hydrogenchloride, then it would create create hydrocloric acid in solution with water.
It could be that as the planet cools (as it moves further away from the star) these substances suspeneded in the atmosphere mix with condensing water vapor and fall to earth as acid rain. This decrease in humidity as the water vapor previously suspeneded in the air falling back to earth may account for some of the drop in temperature.
On areas where the acid rain falls on land, you may have a build up of minieral forms of these compounds (as the moisture evaporates). Maybe these minerals are what is being mined.
