Aims. We study the chemical evolution of the disks of the Milky Way (MW) and of Andromeda (M 31), to identify the common properties and differences between the two major galaxies of the Local Group. Methods. We use a large set of observational data for M 31, including observations of the star formation rate (SFR) and gas profiles, as well as stellar metallicity distributions along its disk. When expressed in terms of the corresponding disk scale lengths, we show that the observed radial… Expand

Chemical Evolution Models for Spiral Disks: the Milky Way, M31 and M33
Context. The distribution of chemical abundances and their variation with time are important tools for understanding the chemical evolution of galaxies. In particular, the study of chemical evolutionExpand
The evolution of the Milky Way: New insights from open clusters
We have collected high-dispersion echelle spectra of red giant members in the twelve open clusters (OCs) and derived stellar parameters and chemical abundances for 26 species by either lineExpand
HERSCHEL EXPLOITATION OF LOCAL GALAXY ANDROMEDA (HELGA). III. THE STAR FORMATION LAW IN M31
We present a detailed study of how the star formation rate (SFR) relates to the interstellar medium (ISM) of M31 at ~140 pc scales. The SFR is calculated using the far-ultraviolet and 24 μm emission,Expand
THE RECENT STELLAR ARCHEOLOGY OF M31—THE NEAREST RED DISK GALAXY*
We examine the star-forming history of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main-sequence stars at distances R{sub GC} > 21 kpc (i.e., >4 disk scaleExpand
The bar of the Andromeda galaxy revealed by integral field spectroscopy
The Andromeda galaxy M31 is the nearest large spiral galaxy to our own Milky Way and therefore gives us the unique opportunity to study this galaxy type in great detail. A longstanding questionExpand
Chemical Evolution of M31
We review chemical evolution models developed for M31 as well as the abundance determinations available for this galaxy. Then we present a recent chemical evolution model for M31 including radial gasExpand
A LARGE GROUP OF ASYMPTOTIC GIANT BRANCH STARS IN THE DISK OF M31: A MISSING PIECE OF THE PUZZLE?
We examine the properties of a stellar grouping that is ~3.5 kpc to the northeast of the center of M31. This structure has (1) a surface brightness that is lower than the surrounding disk, (2) aExpand
The Stellar Archeology of the M33 Disk: Recent Star-forming History and Constraints on the Timing of an Interaction with M31
Images recorded with MegaCam are used to investigate the recent (t {<=} 0.25 Gyr) star-forming history (SFH) of the Local Group Sc galaxy M33. The data sample the entire star-forming disk, as well asExpand
Dissecting simulated disc galaxies - I. The structure of mono-age populations
We study seven simulated disc galaxies, three with a quiescent merger history, and four with mergers in their last 9 Gyr of evolution. We compare their structure at z = 0 by decomposing them intoExpand
The two regimes of the cosmic sSFR evolution are due to spheroids and discs
This paper aims at explaining the two phases in the observed specific star formation rate (sSFR), namely the high (>3/Gyr) values at z>2 and the smooth decrease since z=2. In order to do this, weExpand
