We investigate the thermo-physical evolution of comets in exo-planetary systems in order to provide valuable theoretical data required to interpret observations of gas and dust. We use a quasi 3D model of cometary nucleus to study the thermo-physical evolution of comets evolving around a single star from 0.1 to 50 AU, whose homogeneous luminosity varies from ","authors_text":"Amy Bonsor, Jean-Charles Augereau, Ulysse Marboeuf","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2016-04-13T14:19:42Z","title":"Extrasolar comets : the origin of dust in exozodiacal disks?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.03790","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":"sha256:6ebcbaead8be6f5ec980d5ed00c77b7b1da7a3df6c5668d0425378c644c9aee4","target":"record","created_at":"2026-05-18T01:17:11Z","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":"e179019261626e7481145270252d6c90dcc8277bfbf38015108d4b2d45e5b823","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2016-04-13T14:19:42Z","title_canon_sha256":"5f1083c944f61376ecf7b74c31570eacb693763ff4e9209f90500378289d38b3"},"schema_version":"1.0","source":{"id":"1604.03790","kind":"arxiv","version":1}},"canonical_sha256":"b83ec1c21b05c1b04c29b755667b6b9464e2ad372eec6f0603c5d954c9d9307d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b83ec1c21b05c1b04c29b755667b6b9464e2ad372eec6f0603c5d954c9d9307d","first_computed_at":"2026-05-18T01:17:11.055219Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:17:11.055219Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/auywmjSgk6iqG8Jjj7psHIqPPFwghMN4GowJVFCTw2wkYE+QFrEhU20uRLHdm9sGq395Tw2KUmUHTS+3M80Bg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:17:11.055981Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.03790","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6ebcbaead8be6f5ec980d5ed00c77b7b1da7a3df6c5668d0425378c644c9aee4","sha256:6f0316d3e88c2674c5ce30f116e108fe69f8de00c37fca01db169d10892ccc5b"],"state_sha256":"41862cb10e02f789bdf328c05d4c65279f8c668531e6e1e62448786157843734"}
