Re: Meson alternatives?
Yes, if it's orbiting a supergiant; those figures are on the right scale for the life zones of Betelgeuse and Deneb.

Such stars either don't live long (about two million years for an O7, I think) or they are actually dying, in the process of burning out with a final bright flash. In neither case will planets in these life zones have been warm enough long enough to develop a breathable atmosphere.

Re: Meson alternatives?
I think it actually goes back a little further, though I'm racking my middle-aged brain for details. A panel at a con designed a world on the fly, and on of the members (I think Harlan Ellison) wrote up the results. And they made just this error but with respect to tide-induced prolateness rather than spin-induced oblateness.

Jinx was a high gravity world orbiting a gas giant with an egg-like shape. The poles were actually in vacuum or near vacuum. There may have been a habitable zone between the poles and the equator. Plateau had a massive high altitude plateau where the air was breathable while it was unbreathable at lower altitudes. Clements had a world that spun so fast that gravity was 3 Gs at the equator and 600 at the poles. I don't think he played with the atmosphere much though.

A long time ago I did a writeup of Forboldn that was inspired by Niven's Plateau and Anderson's High America. In a recent discussion I was forced to realize that the atmospheric situation I describe for Forboldn won't work. But I'm still not going to ruin my writeup by niggling attention to details like that, because I think the social and geopolitical situation makes for a fun roleplaying setting. Not so long ago, I came up with an explanation for Heya and it's impossible moon Heya-minor that involves them being co-orbital bodies. Sadly, such a configuration is unstble and wouldn't have lasted long enough. But I'm still going to make them co-orbital bodies, because that's such an awesome concept. And if I ever run a campaign in Jack Vance's Gaean reach, I'm going to keep the Rigel Concourse even if it (as I strongly suspect) doesn't actually work (A naturally occurring rosette of 26 worlds orbiting Rigel in the life zone). And yet, if any of my players were to try to argue that the physical laws of my Traveller universe were different, based on Forboldn or Heya or Dinom, I'd cut him off at the knees. The physical laws aren't different; they're just optional on rare occasions. Hans |
