Hunting Exotic Trojans Around Pulsars Could Rewrite Cosmic Orbits

Astronomers are chasing exotrojans—hypothetical bodies that could orbit pulsars at Lagrange points—by cross-checking optical light curves with pulsar radio timing and analyzing NANOGrav data; so far no conclusive detections, two signals were false positives, and no object bigger than Earth has been found in seven systems, though one showed hints of a body up to eight Jupiter masses, leaving the search open for future data.
