The effect of the metallicity-specific star formation history on double compact object mergers [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We investigate the impact of uncertainty in the metallicity-specific star formation rate over cosmic time on predictions of the rates and masses of double compact object mergers observable through gravitational waves.

The mass–metallicity and the fundamental metallicity relation revisited on a fully Te-based abundance scale for galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The relationships between stellar mass, gas-phase metallicity and star-formation rate (i.e. the mass–metallicity, MZR, and the fundamental metallicity relation, FMR) in the local Universe are revisited by fully anchoring the metallicity determination ...

The progenitors of compact-object binaries: impact of metallicity, common envelope and natal kicks [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Six gravitational wave events have been reported by the LIGO-Virgo collaboration (LVC), five of them associated with black hole binary (BHB) mergers and one with a double neutron star (DNS) merger, while the coalescence of a black hole-neutron star (BHNS)

The Origin of the Mass-Metallicity Relation: Insights from 53,000 Star-forming Galaxies in the Sloan Digital Sky Survey [PDF]
, 2004 We utilize Sloan Digital Sky Survey imaging and spectroscopy of ~53,000 star-forming galaxies at z ~ 0.1 to study the relation between stellar mass and gas-phase metallicity.

Inducing metallicity in graphene nanoribbons via zero-mode superlattices [PDF]
Science, 2019 Making metallic ribbons In its usual two-dimensional form, graphene does not have an energy gap in its electronic structure. However, one-dimensional ribbons made of the material are semiconducting and making them metallic is tricky.

The Close Binary Fraction of Solar-type Stars Is Strongly Anticorrelated with Metallicity [PDF]
Astrophysical Journal, 2018 There is now strong evidence that the close binary fraction (P < 104 days; a < 10 au) of solar-type stars (M1 ≈ 0.6–1.5 ) decreases significantly with metallicity. Although early surveys showed that the observed spectroscopic binary (SB) fractions in the

Grids of stellar models with rotation - I. Models from 0.8 to 120 M⊙ at solar metallicity (Z = 0.014) [PDF]
, 2011 Aims. Many topical astrophysical research areas, such as the properties of planet host stars, the nature of the progenitors of different types of supernovae and gamma ray bursts, and the evolution of galaxies, require complete and homogeneous sets of ...

Resolving the Metallicity Distribution of the Stellar Halo with the H3 Survey [PDF]
Astrophysical Journal, 2019 The Galactic stellar halo is predicted to have formed at least partially from the tidal disruption of accreted dwarf galaxies. This assembly history should be detectable in the orbital and chemical properties of stars.

Metallicity and Superconductivity in Doped Strontium Titanate [PDF]
Annual Review of Condensed Matter Physics, 2018 Strontium titanate is a wide-gap semiconductor avoiding a ferroelectric instability thanks to quantum fluctuations. This proximity leads to strong screening of static Coulomb interaction and paves the way for the emergence of a very dilute metal with ...

Spatial metallicity variations of mono-temperature stellar populations revealed by early-type stars in LAMOST [PDF]
A&A 674, A129 (2023), 2023 We investigate the radial metallicity gradients and azimuthal metallicity distributions on the Galactocentric $X$--$Y$ plane using mono-temperature stellar populations selected from LAMOST MRS young stellar sample. The estimated radial metallicity gradient ranges from $-$0.015\,dex/kpc to $-$0.07\,dex/kpc, which decreases as effective temperature ...
