All of these unusual stars are mid-to-late M dwarfs without evidence of active accretion, and with photometric periods generally $<$1 day. Often the unusual light curve signature takes the form of narrow flux dips; when we also have rotation periods from star spots, the two periods agree, suggesting that the flux dips are du","authors_text":"Andrew Collier Cameron, Ann Marie Cody, David Barrado, James Davenport, John Stauffer, Luisa Rebull, Lynne Hillenbrand, Marc Pinsonneault, Moira Jardine, Scott Wolk, Trevor David","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2017-02-06T21:28:11Z","title":"Orbiting Clouds of Material at the Keplerian Co-Rotation Radius of Rapidly Rotating Low Mass WTTs in Upper Sco"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.01797","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":"sha256:61e2344eb79a9c5020ea71ebfef5d71f38db8383a6af4e3409f80928d88dcc3f","target":"record","created_at":"2026-05-18T00:48:14Z","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":"86e891aeb89cff2a0282adde84f6174fe1f09a4afdcb5dcfc590c8026f6ca795","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2017-02-06T21:28:11Z","title_canon_sha256":"3e332cf18fa6275c7da3e8c684c0444d86ef1c354640d27d56bfdc63b489dfec"},"schema_version":"1.0","source":{"id":"1702.01797","kind":"arxiv","version":1}},"canonical_sha256":"ca5bbbc7e17427a324678a3fb54b33730077f3a5020191616a2af73a50c53874","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ca5bbbc7e17427a324678a3fb54b33730077f3a5020191616a2af73a50c53874","first_computed_at":"2026-05-18T00:48:14.806193Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:14.806193Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Z5mf7QtF8uk2bpJ4/Z0tdvjNZAUNWsk3SKX7GVnKTJj57LPrgGwuohSXj2/vZL5pOLHHWKbg6hvKUMj8eHMHBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:14.806828Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.01797","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:61e2344eb79a9c5020ea71ebfef5d71f38db8383a6af4e3409f80928d88dcc3f","sha256:8decda1cb736b9423ee9dfaa1458c608d4f47b918f98c018f409c54cdbf66a71"],"state_sha256":"fd4e9260e915de6f38209113e163749d298d36278e7a5bb4e7a3883f8564e1a3"}
