Also, the planets are circumbinary making them the first known circumbinary planets to have formed from a protoplanetary disk (the first circumbinary planet PSR B1620-26 C that orbits a pulsar in M4 was most likely captured along its parent star PSR B1620-26 B by the pulsar). |
It's interesting that they are circumbinary, but other than that it's yet another system with super-Jovian planets in eccentric orbits.
The authors seem keen to classify both objects as planets, even suggesting that they must have accreted mass during the primary's red giant phase. Oops, taboo topic.
