In addition to the diffracted and scattered light for the on-axis star, a multi-star system features additional starlight leakage from the off-axis star that must also be controlled. A basic option is for additional starshades to block the off-axis stars. An interesting option takes the form of hybrid operation of a starshade in conjunction with an internal starlight suppression. Two hybrid scenarios are considered. One such scenario includes the coronagraph instrument blocking the on-axis star, with the s","authors_text":"A J Eldorado Riggs, Dan Sirbu, Eduardo Bendek, Elias Holte, Ruslan Belikov, Stuart Shaklan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2017-08-31T18:54:06Z","title":"Prospects for exoplanet imaging in multi-star systems with starshades"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.00041","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":"sha256:7603b3c0e42bfaffde8fba3f1e2b9e356f0a7e24c4e47201f1c8d6364086786e","target":"record","created_at":"2026-05-18T00:36:13Z","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":"6f4b3b26e35ebb619cae67de3233e42eadcfb54e53061b7308c387b3e779021b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2017-08-31T18:54:06Z","title_canon_sha256":"f9a886f4f66df6c997b4a628046878d7f17984cabae8bfcc611201cee6416d51"},"schema_version":"1.0","source":{"id":"1709.00041","kind":"arxiv","version":1}},"canonical_sha256":"af39d94d92c4dc75bb9d65c8a8d6694f857ffd099f3b906ce808d0f07b58b8fb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"af39d94d92c4dc75bb9d65c8a8d6694f857ffd099f3b906ce808d0f07b58b8fb","first_computed_at":"2026-05-18T00:36:13.618113Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:36:13.618113Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"l+co+fl3CKsWh3WOdMQsclKSFQPJajuZRWRUTxfPMmVKg2yZBcHcWgbLPIy4LqbBVMPK0+kYgeh8tHi9aXQbAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:36:13.618719Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.00041","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7603b3c0e42bfaffde8fba3f1e2b9e356f0a7e24c4e47201f1c8d6364086786e","sha256:64008d2977cd96775051b43484c6e384506b4eea9e0951f550711ee00aa5952b"],"state_sha256":"3fc894c690626a2698d0677d743e992f511ccecdee062ae3c02db8c78d170bda"}
