Scattered Star Group in the Orion A
Listed in IVOA Registry (Virtual Observatory)
Using Gaia DR3 data, we identified an extended (~60pc) group of stars sharing common motion but scattered in space, including from 150 to 300 probable members, named Group V. It can be associated with a group identified by Getman et al. (2019MNRAS.487.2977G, Cat.
Description
J/MNRAS/487/2977) and by Jerabkova et al. (2019MNRAS.489.4418J) as a relic of a gas filament, traced by the mutual position of stars after the gas is swept out.
We estimate its age approximately as 16 million years. A combination of methods is applied to select probable members of the Group V. We discuss kinematical characteristics of the stars of Group V and the controversial clues they provide for understanding of its nature. Due to the vicinity of a number of open clusters in the space, differentiating between members of the group and of the clusters is problematic and mutual contamination inevitable.

The pair of clusters Gulliver 6 and UBC 17b is wrapped inside the Group V, but differs from it in kinematics.
