Which processes move the angular momentum, set the states and launch the jets is only partly understood.","title":"Accretion flows, X-ray states and jet launching","topic_ref":null,"why":"Accretion powers quasars, X-ray binaries and most bright high-energy sources, and sets how fast compact objects grow."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"c6622c49671f85d956e06199b59037776536a6db727b79f3ac01839ce91af768","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"661dca6f3c975fab7e26517c87b4c714e4c76fc51e0bbf487adfe2c60efef020","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"byybAcxcMHWfZ6_-p-34HOEN_cqyLp-VnpGVY7FJdEPkgBn2DU4k6Vspjk2ROy4mm759sgv_uHcTHzETJjFIBw"},"schema":"pubphys.envelope/1"},"record_hash":"c6622c49671f85d956e06199b59037776536a6db727b79f3ac01839ce91af768","leaf_index":28}
