* "Unable to verify referring url. Please go back and try again" Problem Logging In?

If you get an "Unable to verify referring url. Please go back and try again" error when you try to log in, you need to be sure you are accessing the board with a url that starts with "https://ecauldron.com".  If it starts with https://www.ecauldron.com" (or "http://www.ecauldron.com") you will get this error because "www.ecauldron.com" is not technically the same website as "ecauldron.com". Moving to the more secure "https" means it is more picky about such things.

55 Cancri
« on: January 12, 2020, 10:10:24 pm »
I was thinking about  55 Cancri, the so-called Diamond Planet https://www.space.com/18011-super-earth-planet-diamond-world.html, and while I don't claim to be an expert on the subject, I don't see the physics working from what I know about planet formation; and the discrepancy between the chemistry of the planet and that of the supposedly parent star further suggests that there is something very wrong with this picture.

Could it be more likely that the planet is actually the burned out core of a dead stellar companion?
And since the parameters and results of the Triple-alpha process of Nucleosynthesis in a Helium-burning star is fairly well understood, this hypothesis should be relatively easy to test
