Another option involving them is the magnetar, a neutron star with an intense magnetic field that's prone to energetic outbursts. But those outbursts also generate more energetic photons, and the researchers checked the site of GPM J1839–10 with an X-ray telescope and saw nothing. Plus, magnetars are thought to rotate more quickly than the 22-minute gap implies, so they're probably out as well.

Just because some random Google result says it’s a magnetar doesn’t make it true. Considering the team that discovered it doesn’t make that claim and as far as I’m aware no one else has looked at this particular star, I think it unlikely that there’s a definitive, widely accepted explanation.
