Planet systems with 'hot Jupiters' PULVERISE innocent strays Hot Jupiter planet systems aren't harbouring any Earthlike worlds because they're too busy systematically decimating any planets that pop up. Jupiter and its volcanic moon Io Boffins have discovered that because of the way so-called hot Jupiters are formed, they're generally the only planets in their systems as they destroy …
I don't see why systematically reducing the number of planets by a mere 10% would rule out Earthlike worlds.... Or did you mean something else when you used the word 'decimate?'
Although I suppose, if the "hot Jupiter" were to continue decimating aeon after aeon, one would end up with a geometric regression type probability scenario...... Oh the mind boggles....
If you thought that was pedantic:
The reason that "decimate" gets confused with "destroy" is that poorer quality dictionaries are loose with their synonyms - they just run a thesaurus scan and pick a few words. Now, "decimate" is perfectly legitimate as a thesaurus related word with "destroy" but you won't find a reputable dictionary giving it as a synonym.
"Destroy a significant proportion of" is the widest common modern definition.
Going by this article, a binary system is one where the "hot Jupiter" has accumulated even more mass and undergone fusion to be come a sun in its own right.
If that's the case then you'd never see that fancy double sunset because your planet wouldn't exist in the first place.
Not if the two suns form in place, with the rest of the system forming around them.
The way I read it, it was the inward migration of the large mass object that swept the system.
Similarly, any bodies outside the sweep of the long elipse as the Jovian migrated inward shouldn't have been too badly affected. Too cold, in all likelihood, to be habitable, of course.
