Could Earth be highlighting Hairy Dark Matter?
...of the roots could be made easier by observing larger planets, as according to Prézeau's simulations, a stream of particles passing through Jupiter's core would produce even denser roots – almost 1 trillion times denser than the original stream. This...

Giant double-planet system around an evolved star detected by astronomers
... composition as the Sun. The planets in question are also on the large side - nearly twice the mass of Jupiter and the two are thought to have an orbital period ratio slightly smaller than 2. Planetary orbits are...

Researchers constrain a possible location for Planet 9 using Cassini data
... have slowed down, the quest to find it has not. Using data gathered from Cassini’s flybys of Saturn, Jupiter and the outer planets to track the positions and velocities of solar system bodies, researchers have constructed...

Researchers show how water content in protoplanetary discs can affect planet formation
... disc, in order to attract a gaseous envelope. Past studies have focused on the abundances of oxygen and carbon in hot Jupiters to determine the location in the disc where the planet accreted, however these studies can be complicated by the...

To build super-Earths near host star 'dead zones' are required say researchers
.... The first is that these planets, that could have an occurrence rate as high as 50% or more compared with hot Jupiters that in turn are only found around about 1% of stars, are formed in situ. Studies have shown this...
