To help understand the origin of this low-mass YSO cluster, the present work aims at resolving the gas structures and kinematics. We have performed $\\sim$1$\"$ angular resolution ($\\sim$930 AU) SMA observations at $\\sim$1.3 mm. From a $\\sim$2$\"$ resolution 1.3 mm continuum image we identified six dense cores, namely SMA1-6 with masses in the range of $\\sim0.4-4$ M$_\\odot$. From a $\\sim$1$\"$ resolution 1.3 mm continuum image, we find a high fragmentation level, with 14"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.08517","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
