J/MNRAS/451/3693    Stellar yields and the initial mass function (Molla+, 2015)

Galactic chemical evolution: stellar yields and the initial mass function. Molla M., Cavichia O., Gavilan M., Gibson B.K. <Mon. Not. R. Astron. Soc., 451, 3693-3708 (2015)> =2015MNRAS.451.3693M (SIMBAD/NED BibCode)
ADC_Keywords: Models, evolutionary ; Milky Way ; Abundances Keywords: stars: abundances - stars: mass-loss - Galaxy: abundances - Galaxy: disc - Galaxy: evolution Abstract: We present a set of 144 Galactic chemical evolution models applied to a Milky Way analogue, computed using four sets of low+intermediate star nucleosynthetic yields, six massive star yield compilations, and six functional forms for the initial mass function. A comparison is made between a grid of multiphase chemical evolution models computed with these yield combinations and empirical data drawn from the Milky Way's disc, including the solar neighbourhood. By means of a χ2 methodology, applied to the results of these multiphase models, the best combination of stellar yields and initial mass function capable of reproducing these observations is identified. Description: These tables give the theoretical chemical evolution models applied for the Milky Way Galaxy (MWG) from the cited paper. Basically give tables 2, 4 of stellar yields used and results of table 6 for the 144 models computed that work. Tables 2 and 4 give the stellar yields q_i(m) and remmnant mass for low and intermediate stars and massive stars, respectively, in a similar format for all authors. Table 6 gives the value of Chi2 for the 144 models computed for MWG using those stellar yields and different Initial Mass Function (see paper). Moreover, we give the table with results of the present time state of the Galactic disk for these 144 models. File Summary:
