As these bubbles expand they encounter the interstellar coherent magnetic field which, depending on its strength, can influence the shape of the bubble. We wish to investigate if, and how much, the interstellar magnetic field can contribute to the shape of an expanding circumstellar bubble around a massive star. We use the MPI-AMRVAC code to make magneto-hydrodynamical simulations of bubbles, using a single star model, combined with several different field strengths: B = 5, 10, and 20 muG for the interstellar ma","authors_text":"Alexandre Marcowith, Allard Jan van Marle, Zakaria Meliani","cross_cats":["astro-ph.GA","astro-ph.HE","physics.space-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2015-09-01T09:34:07Z","title":"Shape and evolution of wind-blown bubbles of massive stars: on the effect of the interstellar magnetic field"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.00192","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6cab5e4cbb358ef61c2f682a00f4290f1db465374e3c9a729deed43d23ad746c","target":"record","created_at":"2026-05-18T01:26:41Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"a313eda220afdd3c3cb076598319388b57da8e346881797d44ec1ec6027e5cc7","cross_cats_sorted":["astro-ph.GA","astro-ph.HE","physics.space-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2015-09-01T09:34:07Z","title_canon_sha256":"d351af08a4715a531fe5c37a1069f5f97ed5db02ea4df11143ce89d28935c9e3"},"schema_version":"1.0","source":{"id":"1509.00192","kind":"arxiv","version":2}},"canonical_sha256":"d15225e40762c2aadd7ffd1b302e8c8cfcfb8b75744ce7649993ef443d5cfb4d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d15225e40762c2aadd7ffd1b302e8c8cfcfb8b75744ce7649993ef443d5cfb4d","first_computed_at":"2026-05-18T01:26:41.793814Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:41.793814Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"guKVzRnGMbuQEHn/Bs/WT7OkY4+6iN5Q8o0HcYNxVIklEgL9n6jYZhB7QOQgoOFsGRcOK9Ff2Qqnkk1jR+L/AA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:41.794550Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.00192","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6cab5e4cbb358ef61c2f682a00f4290f1db465374e3c9a729deed43d23ad746c","sha256:65cc67dde1da90340dc41ffb60699ba0712a0f4688096587fae199a9cce4f590"],"state_sha256":"605964da38e311e91e078834ca8591df3f9685b09de340c1a845c2baadf1fb03"}
