Your talking about heating the atmosphere until the heavier gases can overcome the one gee of gravity and escape. That would take more than a molten surface to do. You would just make the atmosphere puff out more.

Sorry, I apologise, I did not mean any offense, I was just annoyed because I specified my answer 2 times and you still did not understand my question properly and it did not happened for the first time.
Well, but the termosphere temperature is aready around 2000 degress even here.
That's the temperature that matters, not the surface temperature.
And lets not say 1 G, but the gravity of the largest probable natural superterrestrial, say, 15 Earth masses.
According to this applet;
http://www.transhuman.talktalk.net/iw/Geosync.htm
the temperature to which 15 Me planet can retain CO2 atmosphere is 37533 degress Celsius, compared to Earth's maximum of 5942 degress Celsius.
However, there is a problem and that is; that I don't know how to calculate thermosphere temperatures (which are dramatically higher than surface) and I don't know how to take the effects of solar wind into account.
Is there any expert on this who would be able to help me, please?
