cds-question@unistra.freclipsing-binary-starsspectroscopyultraviolet-astronomyThe {zeta} Aurigae system 31 Cygni (K4 Ib + B4 V) was observed by the FUSE satellite during total eclipse and at three phases during chromospheric eclipse. We present the coadded, calibrated spectra and atlases with line identifications. During total eclipse, emission from high ionization states (e.g., Fe III and Cr III) shows asymmetric profiles redshifted from the systemic velocity, while emission from lower ionization states (e.g., Fe II and O I) appears more symmetric and is centered closer to the systemic velocity. Absorption from neutral and singly ionized elements is detected during chromospheric eclipse. Late in chromospheric eclipse, absorption from the K star wind is detected at a terminal velocity of ~80km/s. These atlases will be useful for interpreting the far-UV spectra of other {zeta} Aur systems, as the observed FUSE spectra of 32 Cyg, KQ Pup, and VV Cep during chromospheric eclipse resemble that of 31 Cyg.2014ApJS..211...27Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/211/27CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/129 : The FUSE Observation Log (FUSE, 1999-2007)VI/110 : Final Merged Log of IUE Observations (NASA-ESA, 2000)VI/69 : Atomic Spectral Line List (Hirata+ 1995)III/86 : SKYLAB S-019 Far-UV Objective-Prism Spectrophotometry (Henize+ 1979)J/ApJS/187/149 : StarCAT: STIS UV echelle spectra of stars (Ayres, 2010)J/other/JAD/14.3 : Emission lines in 32 Cygni (Eaton, 2008)J/ApJ/679/1490 : Phot. and Velocity of 3 {zeta} Aur binaries (Eaton+, 2008)J/ApJS/171/249 : Ultraviolet Spectral Atlas of VV Cephei (Bauer+, 2007)J/ApJS/119/83 : IUE sample of binaries with hot component (Parsons+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/211/27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/211/27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/211/27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/211/27https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/211/27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/211/27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVdefaultJ/ApJS/211/27/table1FUSE observations of 31 CygniPhasePhase (1)time.phasefloatrecnoRecord number assigned by the VizieR team.
