RCB stars are carbon-rich supergiants characterized by their extreme hydrogen deficiency and their irregular and spectacular declines in brightness (up to 9 mag). We have analyzed new and archival Spitzer Space Telescope and Herschel Space Observatory data of the envelopes of seven RCB stars to examine the morphology and investigate the origin of these dusty shells. Herschel, in particular, has revealed the first-ever bow shock associated with an RCB star with its observations of SU Tauri. These data have allowed the assembly of the most comprehensive spectral energy distributions (SEDs) of these stars with multiwavelength data from the ultraviolet to the submillimeter. Radiative transfer modeling of the SEDs implies that the RCB stars in this sample are surrounded by an inner warm (up to 1200 K) and an outer cold (up to 200 K) envelope. The outer shells are suggested to contain up to 10^-3^ M_{sun}_ of dust and have existed for up to 10^5^ years depending on the expansion rate of the dust. This age limit indicates that these structures have most likely been formed during the RCB phase.2018AJ....156..148Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/148CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/353/287 : The R CrB stars (Asplund+, 2000)J/A+A/466/L1 : VLTI observations of RY Sgr (Leao+, 2007)J/AJ/134/1877 : Spectropolarimetry of R CrB in 1998-2003 (Kawabata+, 2007)J/AcA/59/335 : VI light curves of LMC R CBr stars (Soszynski+, 2009)J/A+A/539/A51 : Catalogue enriched with R CrB stars (Tisserand, 2012)J/MNRAS/482/4174 : Heliocentric radial velocities of R CrB (Feast+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/148https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/156/148/table1 (Stellar properties and new observations of R Coronae Borealis (RCB) and hydrogen-deficient (HdC) stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/148/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/148/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/148/table1?GETtext/xml+votable180.050000true281.1332083-20.95354720.0055555555555555566/8701 24147 28988 30303 43161 43378 47814 47869 479193.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/156/148?format=asciiOpticalInfrareddefaultJ/AJ/156/148/table1Stellar properties and new observations of R Coronae Borealis (RCB) and hydrogen-deficient (HdC) starsrecnoRecord number assigned by the VizieR team.
