HD 106906b is a singular and puzzling exoplanet . New observations intimate it formed where it could n’t , far from its star than   one would expect .

The exoplanet is 11 multiplication the mass of Jupiter and located 300 low-cal - years aside . It ’s 650 sentence farther from its star than Earth is from the Sun , and that ’s the main progeny . fit in to astronomers , it must have mold outside the debris disk , which is rummy since most satellite commonly form within it . These observations are report inAstrophysical Journal letters .

“ Our current planet organization theories do not account for a planet beyond its rubble disk , ” carbon monoxide gas - source Smadar Naoz , an   assistant professor from   UCLA , said in astatement .

The system is young , not more than 13 million years . It is so   new that the headliner is still surrounded by a tumid magnetic disc of rocky planet - forming cloth . While several young systems have been observed , for exampleTW Hydrae , in those cases the planets were forming inside the debris saucer .

“ This is such a young headliner ; we have a snapshot of a baby maven that just formed its terrestrial system   – a rare peek at the last phase of planet formation , " added   Naoz .

While this external establishment is mysterious , the effect of this exoplanet on the disk is well understood . HD 106906b ’s orbit   is very elliptical and its gravitation has been garble the debris phonograph record . They show via   estimator simulations   that there ’s no need for any more planets to recreate the shape of the disk .

These determination suggest that external planets might be just as important as national planets when it comes to form detritus   disks , and that the chassis is crucial for the orbits of planets .

It is a very exciting prison term to hit the books planetary shaping . We have discovered over 3,450 exoplanets and more are supply every workweek . Each one gives us a piece of a large and complicated mystifier . HD 106906b is the latest piece we have , but there are still a lot more to find before we have an idea of what the full exposure await like .
