We point out that a large number of small scale intermittent shock waves can be present in the solar corona. The energization mechanism is, essentially, the ion reflection off supercritical quasi-perpendicular collisionless shocks in the corona and the subsequent acceleration by the motional electric field ${\\bf E} = - (1/c) {\\bf V} \\times {\\bf B}$. The acceleration due to ${\\bf E}$ is perpendicular to the magnetic field, in agreement with observations, and is ","authors_text":"Gaetano Zimbardo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2009-06-17T17:09:31Z","title":"More than mass proportional heating of heavy ions by supercritical collisionless shocks in the solar corona"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0906.3243","kind":"arxiv","version":1},"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:e4ff78fc9cd895db6fc043988824cd82b0adb4aba060511fb96158606c5a6c04","target":"record","created_at":"2026-05-18T04:33:39Z","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":"2f59c6f14856329ab440b0c7dfa98e1a768b2102c90536e24ba32249dfbfc397","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2009-06-17T17:09:31Z","title_canon_sha256":"f737d771afb418707dcd090baf798349f90d8eace8378571841687ac785a863a"},"schema_version":"1.0","source":{"id":"0906.3243","kind":"arxiv","version":1}},"canonical_sha256":"d0f930025ebec2c10ed39541de8c819db14124a7b59ffd2805352cfe08dc21b3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d0f930025ebec2c10ed39541de8c819db14124a7b59ffd2805352cfe08dc21b3","first_computed_at":"2026-05-18T04:33:39.926276Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:33:39.926276Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YFIgPFG+TAUd28NESmckyENBN0aKJ30+hu6kuWpn9YpxBNqDXcJ+ziqgx25fPgSgIWxjgOgRN2JXCBNzYunzCg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:33:39.927698Z","signed_message":"canonical_sha256_bytes"},"source_id":"0906.3243","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e4ff78fc9cd895db6fc043988824cd82b0adb4aba060511fb96158606c5a6c04","sha256:9c57ab7fc323c1b2d69ff7897ce4d734eb81126345ea5397f02262fb1d944cba"],"state_sha256":"c499d09083e4819f1acbfb03b0336bb9289321409dd595db383788b2b0d24232"}
