cds-question@unistra.frexoplanetschemical-abundancesvisible-astronomyspectroscopyhigh-velocity-starsIt has been suggested that {beta}Picb has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star {beta}Pic and therefore the planet's parent protoplanetary disk, {beta}Picb's C/O ratio suggests that it formed via core accretion between its parent protoplanetary disk's H2O and CO2 ice lines. However, {beta}Picb's high metallicity is difficult to reconcile with its mass Mp=11.7MJup. Massive stars can present peculiar photospheric abundances that are unlikely to record the abundances of their former protoplanetary disks. This issue can be overcome for early-type stars in moving groups by inferring the elemental abundances of the FGK-stars in the same moving group that formed in the same molecular cloud and presumably share the same composition. We infer the photospheric abundances of the F-dwarf HD181327, a {beta}Pic moving group member that is the best available proxy for the composition of {beta}Picb's parent protoplanetary disk. In parallel, we infer updated atmospheric abundances for {beta}Picb. As expected for a planet of its mass formed via core-accretion beyond its parent protoplanetary disk's H2O ice line, we find that {beta}Picb's atmosphere is consistent with stellar metallicity and confirm that it has superstellar carbon and oxygen abundances with a substellar C/O ratio. We propose that the elemental abundances of FGK dwarfs in moving groups can be used as proxies for the otherwise difficult-to-infer elemental abundances of early-type and late-type members of the same moving groups.2024AJ....167...45Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/167/45CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/simbad : Simbad objects catalogue (M.Wenger 2000)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJ/743/156 : NEOWISE obs of NEOs; preliminary results (Mainzer+, 2011)J/A+A/564/A125 : AGN Torus model comparison AGN in the CDFS (Buchner+, 2014)J/AJ/151/144 : ASPCAP weights for 15 APOGEE elements (Garcia+, 2016)J/MNRAS/474/5158 : Stars with hot Jupiter exoplanets (Goyal+, 2018)J/A+A/630/A104 : Disk and halo stars C, O and Fe abundances (Amarsi+, 2019)J/A+A/626/A80 : Census of RhoOph candidate membs Gaia DR2 (Canovas+, 2019)J/A+A/630/A137 : Structure and kinematics of the Taurus region (Galli+, 2019)J/A+A/627/A177 : Non-LTE analysis of K I in late-type stars (Reggiani+, 2019)J/A+A/634/A98 : Corona-Australis DANCe.
