And, critically, the whole orbit is in the orbit of the small partner. The hard binary gravity forces should prevent any planet from forming within this place at the beginning of the history of the system. So, how did the planet end up in such an unusual order?
A confused past
The fact is that one of the stars in the octanes is white dwarf suggests some potential specifications. White dwarves are formed by stars like the sun, which have developed the late helium burning period, causing them to flourish largely, causing the exterior of the star to weaken the rest of it. ν At a distance of the octanes, it will allow the external partner to pull enough content and now to the main star level. Pure result is a large number of massive transitions.
It could have done one of two works to keep the planet in the interior of the system. One is that the transfer material is unlikely to dive immediately at the surface of the nearby star. If this process is slow enough, it could produce a planet-forming disk for a short term-which is enough to develop a planet on the interior of the system.
As an alternative, if there were planets in the outer part of the two stars, changes in the mass distribution of the system could potentially destabilize their orbit. It can cause interaction between the planets so that one of them can be sent to the inside, where he was eventually caught in a stable retrotography orbit that we now find.
In any case, the authors emphasized, should be very rare, which means that we do not have the possibility of imaging many other such systems at this stage of the study of explanatics. They point to another tough binary, HD 59686, which seems to have a planet in the retrograde orbit. But, as ν ν, like the octanes, the data is not so clear to reject alternative settings. So, once again, more data is needed.
