The one with a higher magnetic field of $10^{14}$ - $10^{15}$ G is called magnetar, characterized with repeated short bursts, and the other is X-ray isolated neutron star (XINS) with $10^{13}$ G. Both magnetars and XINSs show thermal emission in X-rays, but it has been considered that the thermal spectrum of magnetars is reproduced with a two-temperature blackbody (2BB), while that of XINSs shows only a single-temperature blackbody (1BB) and the temperature is ","authors_text":"Hironori Matsumoto, Hiroshi Nakajima, Kiyoshi Hayashida, Tomokage Yoneyama","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-11-29T06:37:48Z","title":"Universal detection of high-temperature emission in X-ray Isolated Neutron Stars"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.11982","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":"sha256:676c23e0476a0a306aebac7fecbb141265d43b3e64e0dd67560a15e7aaf8a01f","target":"record","created_at":"2026-05-17T23:59:34Z","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":"558ecb3796eac17d1f35f3dce890d5b7e58f5ee8ba95eedc40383f9e365a0e36","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-11-29T06:37:48Z","title_canon_sha256":"c62ba0fe89647d45dfcf67b89620a4a9ede9b1bd9eb6e61cc59d2dddf1cde372"},"schema_version":"1.0","source":{"id":"1811.11982","kind":"arxiv","version":1}},"canonical_sha256":"391ca5a714c64ec319fd53559659fdae6e4036d95f013883fba1259685b0ccdf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"391ca5a714c64ec319fd53559659fdae6e4036d95f013883fba1259685b0ccdf","first_computed_at":"2026-05-17T23:59:34.846185Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:34.846185Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"V5J7iifgVSUaL3tNwrpuXmabsjFJPU2gMil9b0o+1wPN35JoA5v+Ql1hnH/J8vgOq5SwnuN+vvjfPQAVHE/pBg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:34.846865Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.11982","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:676c23e0476a0a306aebac7fecbb141265d43b3e64e0dd67560a15e7aaf8a01f","sha256:8602d6a967ae3e2477e5470c6fb91513908d93505fd2878c42a32419cf312663"],"state_sha256":"0bf2f54ae6082a3f65b4680a3b448b724c9c285bf2d1dbbbef9fed303f953b56"}
