Our sample includes the Trojan (1172) Aneas, which is one of three Trojans known to possess a comet-like 10 micron emission feature, indicative of fine-grained silicates. Our observations show that all seven Trojans appear featureless in high signal-to-noise ratio spectra. The simultaneous absence of the 1 micron band and presence of the 10 micron emission can be understood if the silicates on (1172) Aneas are iron-poor.","authors_text":"Bin Yang, David Jewitt","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2011-01-26T21:23:44Z","title":"A Near-Infrared Search for Silicates in Jovian Trojan Asteroids"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.5167","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:aafc74dfd68ca6bc1df0be802bbabfaa4a0afc84029ae86f89ee874b0b5090da","target":"record","created_at":"2026-05-18T02:03:21Z","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":"e71ab7b663eedc97491b3e0b694f096da1830303cce6eeb03dec703e9246152b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2011-01-26T21:23:44Z","title_canon_sha256":"386ab5add6259afc2b5eaaea43ac50586ea6e220a99a07c5f3b38c6f2d7a3ad5"},"schema_version":"1.0","source":{"id":"1101.5167","kind":"arxiv","version":1}},"canonical_sha256":"43bc4b3962c4c70624a6ef65601398ea7695b9d3b3ee1d888e24f8b307bdf446","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"43bc4b3962c4c70624a6ef65601398ea7695b9d3b3ee1d888e24f8b307bdf446","first_computed_at":"2026-05-18T02:03:21.651233Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:03:21.651233Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ftH2epjwg37qHjfZyv5HKSS0RkGqqOZBuqqpqW4AflnmX92nDDwIqvcZ6JJEPFr55jIJ5CnUAXWgOx9mKuU4BA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:03:21.651993Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.5167","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:aafc74dfd68ca6bc1df0be802bbabfaa4a0afc84029ae86f89ee874b0b5090da","sha256:6cd84cfc3e04dec0fa373f21004962968c204ea4d852bb32f3bf1edea0de210f"],"state_sha256":"a30a4294d69f370725f0b4781acf7f9456466d6a3f22bc3003bcce8e6b532d77"}
