the abstract. Daniel Pomarède, one of the authors is open in ORCiD about his work. I found that he has a presence on Wikidata by searching for his ORCiD id: "0000-0003-2038-0488".
Marking Mr Pomarède for an update is what it takes to give the article I think is interesting more of an audience. In the process there will be more to read about this part of astronomy.
