We have therefore obtained an XMM-Newton observation of HD155806 and 1RXSJ171502.4-333344, and derived their spectral properties for the first time. The X-ray spectrum of HD155806 appears soft, even slightly softer than usual for O-type stars (as shown by a comparison with the O9 star HD155889 in the same XMM field). It is well-fitted with a two-component thermal model with low temperatures (0.2 and 0.6 keV), and it shows no overluminosity (log[LX/Lbol]=-6.75). The high-resolution spectrum, though noisy, reveals a few b","authors_text":"Asif ud-Doula (Morrisville State Col.), Gregor Rauw (ULg), Yael Naze","cross_cats":["astro-ph.SR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-12-02T10:08:59Z","title":"Hot and cool: two emission-line stars with constrasting behaviours in the same XMM-Newton field"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0912.0379","kind":"arxiv","version":3},"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":"sha256:5e4d1459f188b1bac5708817b5d7b233a5b6d5931f07b22a12af1eef6ebb9d51","target":"record","created_at":"2026-05-18T02:10:34Z","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":"609433813c4bb5caf76baf49dfdca2f7ea7085f18538b2971fd058a08fe3a4a6","cross_cats_sorted":["astro-ph.SR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-12-02T10:08:59Z","title_canon_sha256":"78a66bbfb4892dc9b3525a58a6b0a6bbefc109cd0ed77a29af153ed117aa3805"},"schema_version":"1.0","source":{"id":"0912.0379","kind":"arxiv","version":3}},"canonical_sha256":"86275b9e5d827d104f2cdbf8b1b8648724845edd7bb3213d6bb81c5fbccc83c0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"86275b9e5d827d104f2cdbf8b1b8648724845edd7bb3213d6bb81c5fbccc83c0","first_computed_at":"2026-05-18T02:10:34.659477Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:10:34.659477Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Vu1cI0HaehB65ikDjTu/rAtWaantknqlRZ3S+ZCYBtBf0GzBknsTfUc3xOk57M864/31+/0YO/J/9MSy9ERSBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:10:34.660125Z","signed_message":"canonical_sha256_bytes"},"source_id":"0912.0379","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5e4d1459f188b1bac5708817b5d7b233a5b6d5931f07b22a12af1eef6ebb9d51","sha256:1125bf0b07940d51d904f837177a650c07d90b0b9c8e1be7db6eb8929c860b50"],"state_sha256":"5ae6eafdc452b10d94da28d395cef24fdc990733c5f7618070fe26bd21e121e3"}
