The Fate of HR 8799

Tale of a star's destruction, this part in the abstract I find interesting:
"We find that (i) giant branch mass loss always breaks the resonance,and usually triggers the ejection of two of the planets, (ii) stellar flybys and Galactic tides rarely break the resonance during the main-sequence and giant branch phases,but play a crucial role in determining the final planetary configurations around the eventual white dwarf host star, and (iii) the meanderings of the surviving planets vary significantly, occupying regions from under 1 au to thousands of au. The ubiquitous survival of at least one planet and the presence of the debris discs in the system should allow for dynamical pathways for the white dwarf to be metal-polluted."
It appears to be saying that one of the planets may survive, along with a debris disc.
