New star clusters towards Galactic anticentre
Listed in IVOA Registry (Virtual Observatory)
We report the discovery of 31 new open clusters (OCs) identified in Gaia DR3 data through a systematic search over 220 adjacent 1{deg}*1{deg} fields towards the Galactic anticentre, in the direction of the Perseus arm gap.
Description
Eight of them display low-density structures, possibly indicating open cluster remnants properties. The objects were identified and characterized through a combined analysis of photometric, kinematic, and spatial distributions, a methodology successfully applied in our previous works.
Their structural properties, mean proper motions, ages, distances and reddening were derived and their centres cross-matched with the available catalogues. The clusters are low-concentrated systems and are mostly located within $34$ kpc. They do not belong to the Perseus arm, but may be associated with the Outer Norma arm.

The Gulf of Camelopardalis region appears as an interruption in the Perseus arm, possibly reflecting low star-formation activity, dust obscuration, or that the Milky Way is a flocculent, rather than a grand-design spiral galaxy.
