A Bayesian chemical evolution model of the DustPedia Galaxy M74
Francesco Calura, Marco Palla, Laura Morselli +8
We introduce a new, multi-zone chemical evolution model of the DustPedia galaxy M74, calibrated by means of MCMC methods. We take into account the observed stellar and gas density…
Disc dichotomy signature in the vertical distribution of [Mg/Fe] and the delayed gas infall scenario
E. Spitoni, V. Aguirre Børsen-Koch, K. Verma +1
The analysis of the APOGEE data suggests the existence of a clear distinction between two sequences of disc stars in the [/Fe] vs. [Fe/H] abundance ratio space. We aim to test i…
An observational testbed for cosmological zoom-in simulations: constraining stellar migration in the solar cylinder using asteroseismology
Kuldeep Verma, Robert J. J. Grand, Víctor Silva Aguirre +1
Large-scale stellar surveys coupled with recent developments in magneto-hydrodynamical simulations of the formation of Milky Way-mass galaxies provide an unparalleled opportunity t…
APOGEE DR16: a multi-zone chemical evolution model for the Galactic disc based on MCMC methods
E. Spitoni, K. Verma, V. Silva Aguirre +6
The analysis of the APOGEE DR16 data suggests the existence of a clear distinction between two sequences of disc stars at different Galactocentric distances in the [/Fe] vs. [Fe…
Galactic Archaeology with asteroseismic ages. II. Confirmation of a delayed gas infall using Bayesian analysis based on MCMC methods
E. Spitoni, K. Verma, V. Silva Aguirre +1
With the wealth of information from large surveys and observational campaigns in the contemporary era, it is critical to properly exploit the data to constrain the parameters of Ga…
Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi
William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81
Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
