Star formation sustained by gas accretion

J Sánchez Almeida, BG Elmegreen… - The Astronomy and …, 2014 - Springer
Numerical simulations predict that metal-poor gas accretion from the cosmic web fuels the
formation of disk galaxies. This paper discusses how cosmic gas accretion controls star …

Galactic Archaeology with asteroseismic ages: Evidence for delayed gas infall in the formation of the Milky Way disc

E Spitoni, VS Aguirre, F Matteucci, F Calura… - Astronomy & …, 2019 - aanda.org
Context. Precise stellar ages from asteroseismology have become available and can help to
set stronger constraints on the evolution of the Galactic disc components. Recently …

APOGEE DR16: A multi-zone chemical evolution model for the Galactic disc based on MCMC methods

E Spitoni, K Verma, VS Aguirre, F Vincenzo… - Astronomy & …, 2021 - aanda.org

Evolution Experiment project (APOGEE DR16) data suggests the existence of a clear …

Accretion-driven turbulence as universal process: galaxies, molecular clouds, and protostellar disks

RS Klessen, P Hennebelle - Astronomy & Astrophysics, 2010 - aanda.org
Context. Even though turbulent motions are found everywhere in astrophysical systems, the
origin of this turbulence is poorly understood. When cosmic structures form, they grow in …

[图书][B] Chemical evolution of galaxies

F Matteucci - 2012 - books.google.com
The term “chemical evolution of galaxies” refers to the evolution of abundances of chemical
species in galaxies, which is due to nuclear processes occurring in stars and to gas flows …

Gas accretion via condensation and fountains

F Fraternali - Gas Accretion onto Galaxies, 2017 - Springer
For most of their lives, galaxies are surrounded by large and massive coronae of hot gas,
which constitute vast reservoirs for gas accretion. This chapter describes a mechanism that …

Beyond the two-infall model-I. Indications for a recent gas infall with Gaia DR3 chemical abundances

E Spitoni, A Recio-Blanco, P de Laverny… - Astronomy & …, 2023 - aanda.org
Context. The recent Gaia Data Release 3 (DR3) represents an unparalleled revolution in
Galactic archaeology, providing numerous radial velocities and chemical abundances for …

Supernova-driven gas accretion in the Milky Way

A Marasco, F Fraternali, JJ Binney - Monthly Notices of the Royal …, 2012 - academic.oup.com
We use a model of the Galactic fountain to simulate the neutral-hydrogen emission of the
Milky Way Galaxy. The model was developed to account for data on external galaxies with …

Dwarf galaxy archaeology from chemical abundances and star-formation histories
