Based primarily on the presence of broad, asymmetric Halpha emission, we have identified 13 objects (~30% of our sample) which are strong candidates for ongoing accretion. At least 3 of these are substellar. We do not detect significant continuum veiling in most of the accretors with late spectral types (M5-M7). Accretion shock models show that lack of measurable veiling allows us to place an upper limit to the mass ac","authors_text":"Cesar Briceno (CIDA), James Muzerolle (Steward), Lee Hartmann (CfA), Lynne Hillenbrand (Caltech), Nuria Calvet (CfA)","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2003-04-03T18:13:23Z","title":"Accretion in Young Stellar/Substellar Objects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0304078","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":"sha256:1e1f3417f23f9ba06a6ed3ac54a3ac381f9b32a488039d3ca2c8a9f0baa06457","target":"record","created_at":"2026-07-04T15:45:42Z","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":"a699f33325719a665efdc528dfabe4575d92371857ee0eaa51a82ada70818a5d","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2003-04-03T18:13:23Z","title_canon_sha256":"00acc9632f4cf1a57bdd02751c0fb359a42b2cd543e97d219c8c478ad4ca1034"},"schema_version":"1.0","source":{"id":"astro-ph/0304078","kind":"arxiv","version":1}},"canonical_sha256":"a10a7c8b1b60d99b2ebcf000f1875b214212545cfc99009d57fa0dbdfd94fedb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a10a7c8b1b60d99b2ebcf000f1875b214212545cfc99009d57fa0dbdfd94fedb","first_computed_at":"2026-07-04T15:45:42.192398Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:45:42.192398Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"auBed7s/XNr3nCcPF/q8wDx7OiCTvGHdV65ss8q8C2iFilZcpS8y4Z1BUqSihiqtS9kuUgmXt/UM6Slg5YkpBA==","signature_status":"signed_v1","signed_at":"2026-07-04T15:45:42.192820Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0304078","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1e1f3417f23f9ba06a6ed3ac54a3ac381f9b32a488039d3ca2c8a9f0baa06457","sha256:9ef3f825879fa5e9291ac602afbc2d4c55987f8c6dc31f8a2bef4d248a56f52e"],"state_sha256":"dffbdfc139ee48ce8071add2966249867cd0b7fc683bf455ec340f210802c17c"}
