HUMANS are not alone in struggling to stay slim. Some planets go through a "fat" stage that swells their waistlines temporarily, which possibly explains why some gas giants are unexpectedly large.
"Astronomers have power leveling found a lot of planets whose sizes cannot be explained by standard theory," says Laurent Ibgui of Princeton University. The difference between predicted and measured widths of so-called "hot Jupiters" can be 30 per cent or more.
Previously, astronomers assumed that, because cold gas takes up less volume than hot gas, hot Jupiters would shrink as they lost their initial heat.

Now a computer simulation by Ibgui suggests this effect can be temporarily halted in hot Jupiters that begin life in highly elliptical orbits. These planets are alternately squeezed and stretched as they circle their stars, resulting in "tidal heating" that warms the gas inside the planet. This counteracts the cooling effect, inflating the planet - an effect that can last for a billion years or more. Eventually, though, the planet's orbit will become more circular, and the hot Jupiter resumes shrinking. Ibgui presented the research at an American Astronomical Society meeting in Pasadena, California, last week.

The model doesn't quite explain the superpuffy appearance of all hot Jupiters, says Jonathan Fortney of the University of California, Santa Cruz. "It requires these planets to start their lives on very eccentric orbits, which is possible, but not currently the preferred scenario." |

What's the official site say this game?
wow power leveling
The team is beginning to list out some of the systems and features that it's looking at for future tweaks.wow power leveling Street issues a caveat by saying that this is a preliminary list and not necessarily all-inclusive.
We have very few traditional tank and spank fights (even Argaloth likes to parry melee) so it’s hard to get consistent numbers without very large data sets. Still, we see Survival hunters and Unholy DKs on top of a lot of single target fights.wow power leveling Arcane,wow power leveling Marksman, and Beastmaster damage is too low. Retribution, Shadow, and Fire and Frost mage damage might be too low, but we’re still watching them. We aren’t seeing a lot of Subtlety rogues in PvE yet,world of warcraft power leveling so that sample size is still small.world of warcraft power leveling On fights where there is a lot of area damage, Demonology warlocks, Frost DKs and possibly Survival hunters are all too high.world of warcraft power leveling Shadow priest AE, mostly due to a weak Mind Sear, feels too low.world of warcraft power leveling Healing in PvE is working out pretty much as intended. There are some Heroic dungeon bosses that are probably tougher than the required item level average permits. In general, you might have a tough time upon zoning into a Heroic dungeon with a bunch of strangers as soon as Dungeon Finder permits, especially if your group isn’t willing to communicate and work together.cheap wow power leveling We want Heroics to be challenging -- if you want to zerg the content,cheap wow power leveling stick to normal dungeons.Tank balance overall seems good at this point in time.buy wow gold, Threat seems to be in a good place -- good tanks don’t have much of a problem,buy wow gold but they can’t “phone it in” either. We’re seeing all four tanks get a lot of use, even on Heroic raid fights. That could change as more guilds are able to make serious heroic attempts. |
