Dual-band photometry revealed that the $g'-i'$ color reddened with a decrease in brightness, during the main superoutburst and the following rebrightening phase, whereas the color became bluer with a further decrease in brightness during the slow, final decline phase. With a fit to our photometric results by a blackbody function, we estimated the disk radius ratio (ratio of the disk radius to the binary separatio","authors_text":"Akira Arai, Atsunori Yonehara, Daisaku Nogami, Hideyo Kawakita, Makoto Uemura, Mizuki Isogai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2014-10-21T20:00:07Z","title":"Optical Dual-Band Photometry and Spectroscopy of the WZ Sge-Type Dwarf Nova EZ Lyn during the 2010 Superoutburst"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.5822","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:ed35ac419ed84ace67bf9f06bdb1745737deeae314500e8a6eb80ab7a660c92f","target":"record","created_at":"2026-05-18T01:41:41Z","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":"436f8d9c6fcb1ae9b2b21dc6b21fc8c81678b61facbeb32d5cc7d6c5e870cefb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2014-10-21T20:00:07Z","title_canon_sha256":"c1da60198ea3b10cc7ebbe98bce702ca50662922efddd13bc04bcf09be0c990f"},"schema_version":"1.0","source":{"id":"1410.5822","kind":"arxiv","version":1}},"canonical_sha256":"712ec13c1a633c4cab968bf43b73897945f1c059eed5dd4f8daad6cacdc37fda","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"712ec13c1a633c4cab968bf43b73897945f1c059eed5dd4f8daad6cacdc37fda","first_computed_at":"2026-05-18T01:41:41.299838Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:41:41.299838Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ojoKeW0MJb6YRGVu8ipR9fXrNwW4KOJcXraoXb2bl3wRBDGYUtrJ8S9y6+wCL0QncXGHcr5kJnzsNpJllworDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:41:41.300307Z","signed_message":"canonical_sha256_bytes"},"source_id":"1410.5822","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ed35ac419ed84ace67bf9f06bdb1745737deeae314500e8a6eb80ab7a660c92f","sha256:65ec95c72d4f852dc17efb8d5fc8a11789bcd7cb196b2fe6aaeaeead4145bacf"],"state_sha256":"ba6689b0df5da68812ad29d4ef0242278636aaa37867f18fcc38a86da9e849a5"}
