Interpreting the current dynamics, we speculate that PerOB2 may have formed from two separate clouds that have begun forming stars in close proximity to each other. IC348 is caught in the middle between the two of them, inheriting kinematics of both, and it stands out as a possible site of cloud-cloud interaction. We also consider the possibility of a past supernova in PerOB2-while one has likely occurred, it does not appear to have caused any obvious triggered star formation, but it has created a shock that has swept the molecular gas away from IC348. Finally, we examine a recently proposed shell between Taurus and Perseus. While its origin is unknown, we find no support for an expanding bubble in stellar kinematics, nor can we identify a likely progenitor for a supernova that may have caused it, disfavoring this scenario in the formation of this apparent shell.2022AJ....164...57Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/57CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)V/156 : LAMOST DR7 catalogs (Luo+, 2019)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/57https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/57http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/57https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/57https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/57http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/57GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/164/57/table1 (Candidate members of young groups in perseus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/57/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/57/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/57/table1?GETtext/xml+votable180.050000true56.7505469429.1888650.0055555555555555565/302 310 384-386 388 390 6/511 853 855 859 861-862 880-881 1191 1194-1195 1197-1199 1202-1203 1212-1214 1230-1231 1249 1252-1253 1262 1264 1548-1549 1551https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/164/57?format=asciiOpticaldefaultJ/AJ/164/57/table1Candidate members of young groups in perseusrecnoRecord number assigned by the VizieR team.
