VizieR Online Data Catalog: Evolutionary traits for stellar phylogeny (Jackson+, 2021)
Abstract
Chemical abundance and kinematic data and errors are given for a sample of 78 solar twins (including the Sun). We use chemical abundances and stellar ages that have been determined and published for this sample by Bedell et al. (2018, Cat. J/ApJ/865/68). Since many chemical elements are produced at similar astrophysical sites, we have chosen traits that are evolutionary informative (Jofre et al., 2020, Cat. J/A+A/633/L9). We select the abundance ratios presented in Jofre et al. (2020, Cat. J/A+A/633/L9) to produce our evolutionary tree. These correspond to [C/Y], [C/Zr], [C/Ba], [C/La], [C/Ce], [C/Nd], [O/Y], [O/Ba], [Na/Sr], [Na/Y], [Na/Zr], [Na/Ba], [Na/La], [Na/Ce], [Na/Nd], [Mg/Sr], [Mg/Y], [Mg/Zr], [Mg/Ba], [Mg/La], [Mg/Ce], [Mg/Nd], [Al/Y], [Al/Ba], [Si/Zr], [Si/Ba], [Si/La], [Si/Ce], [Ca/Ba], [Sc/Sr], [Sc/Y], [Sc/Zr], [Sc/Ba], [Sc/La], [Sc/Ce], [Sc/Ba], [Ti/Y], [Ti/Ba], [Ti/Ba], [Mn/Y], [Mn/Ba], [Co/Ba], [Ni/Sr], [Ni/Y], [Ni/Zr], [Ni/Ba], [Ni/La], [Ni/Ce], [Cu/Sr], [Cu/Y], [Cu/Zr], [Cu/Ba], [Cu/La], [Cu/Ce], [Zn/Ba]. Kinematic information is taken from the HARPS data and the second data release (DR2) of Gaia (Gaia Collaboration et al., 2018, Cat. I/345). The kinematics are analysed in terms of actions and birth radii.
