cds-question@unistra.frplanetary-nebulaechemical-abundancesspectroscopyWe have performed a comprehensive chemical abundance analysis of the extremely metal-poor ([Ar/H]<-2) halo planetary nebula (PN) BoBn 1 based on International Ultraviolet Explorer archive data, Subaru/High-Dispersion Spectrograph spectra, VLT/UVES archive data, and Spitzer/IRS spectra. We have detected over 600 lines in total and calculated ionic and elemental abundances of 13 elements using detected optical recombination lines (ORLs) and collisionally excited lines (CELs). The estimations of C, N, O, and Ne abundances from the ORLs and Kr, Xe, and Ba from the CELs are done the first for this nebula, empirically and theoretically. We have detected five fluorine and several slow neutron capture elements (the s-process). The amounts of [F/H], [Kr/H], and [Xe/H] suggest that BoBn 1 is the most F-rich among F-detected PNe and is a heavy s-process element rich PN. We have confirmed dust in the nebula that is composed of amorphous carbon and polycyclic aromatic hydrocarbons with a total mass of 5.8x10^-6^M_{sun}_. The photoionization models built with non-LTE theoretical stellar atmospheres indicate that the progenitor was a 1-1.5M_{sun}_ star that would evolve into a white dwarf with an ~0.62M_{sun}_ core mass and ~0.09M_{sun}_ ionized nebula. We have measured a heliocentric radial velocity of +191.6+/-1.3km/s and expansion velocity 2V_exp_ of 40.5+/-3.3km/s from an average over 300 lines.2010ApJ...723..658Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/723/658CatalogResearchIsServedByTAP VizieR generic servicerelated-toIV/24 : Catalogue of Galactic Planetary Nebulae (Kohoutek, 2001)VI/110 : Final Merged Log of IUE Observations (NASA-ESA, 2000)V/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)J/ApJ/714/1096 : Galactic planetary nebulae (Stanghellini+, 2010)J/PAZh/35/574 : He, C, N and O abundances in PNe (Milanova+, 2009)J/A+A/479/155 : Proper motions of Galactic Planetary Nebulae (Kerber+, 2008)J/A+A/475/217 : Classification of planetary nebulae (Quireza+, 2007)J/MNRAS/349/793 : Galactic PNe abundances (Perinotto+, 2004)J/A+A/408/1029 : Coordinates of Galactic planetary nebulae (Kerber+, 2003)J/AN/323/484 : Accurate coordinates of Planetary Nebulae (Kohoutek+, 2002)J/other/RMxAA/37.115 : Optical coordinates of southern PNe (Kimeswenger+, 2001)J/A+AS/132/13 : Planetary nebulae radial velocities (Durand+ 1998)J/ApJS/117/361 : PNe in NRAO VLA Sky Survey (Condon+ 1998)J/AJ/112/1188 : HK survey emission-line candidates (Beers+ 1996)J/A+AS/94/399 : Absolute fluxes and distances of PN (Cahn+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/723/658https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/723/658http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/723/658https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/723/658https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/723/658http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/723/658GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/723/658/table23Observed and reddening corrected line ratios and identifications of BoBn 1recnoRecord number assigned by the VizieR team.
