Image Details
Caption: Figure 6.
Same as Figure 4, but for the populations cospatial or comoving with AriS, VulE, or TOR1B at formation, which comprise the Orion Family. Most populations exhibit divergence, and AriS and TOR1B formed outbound from the center of Orion, consistent with an origin in the enclosing Orion–Eridanus Superbubble. VulE’s connection to Orion is less clear, but it may have interacted with the progenitor clouds to NGC 2232 and LP 2439.
