Universe, 2022 In this paper, we make use of data collected for open cluster members by high-resolution spectroscopic surveys and programmes (i.e., APOGEE, Gaia-ESO, GALAH, OCCASO, and SPA). These data have been homogenised and then analysed as a whole.

Heavy Metal Rules. I. Exoplanet Incidence and Metallicity
Geosciences, 2019 The discovery of only a handful of exoplanets required establishing a correlation between giant planet occurrence and metallicity of their host stars.

The chemical enrichment in the early Universe as probed by JWST via direct metallicity measurements at z ∼ 8 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We analyse the chemical properties of three z∼ 8 galaxies behind the galaxy cluster SMACS J0723.3-7327, observed as part of the Early Release Observations programme of the James Webb Space Telescope (JWST).

Nanomaterials, 2021 Determining the metallicity and semiconductivity of a multi-walled carbon nanotube (MWCNT) bundle plays a particularly vital role in its interconnection with the metal electrode of an integrated circuit.

Astrophysical Journal Supplement Series, 2023 We present the evolution of the mass–metallicity (MZ) relation at z = 4–10 derived with 135 galaxies identified in JWST/NIRSpec data taken from the three major public spectroscopy programs of ERO, GLASS, and CEERS.

Progenitors of Long-Duration Gamma-ray Bursts
Galaxies, 2021 We review the current scenario of long-duration Gamma-ray burst (LGRB) progenitors, and in addition, present models of massive stars for a mass range of 10–150M⊙ with ΔM=10M⊙ and rotation rate v/vcrit=0 to 0.6 with a velocity resolution Δv/vcrit=0.1.

The MOSDEF Survey: The Variation of the Dust Attenuation Curve with Metallicity [PDF]
Astrophysical Journal, 2020 We derive a UV-optical stellar dust attenuation curve of galaxies at z = 1.4–2.6 as a function of gas-phase metallicity. We use a sample of 218 star-forming galaxies, excluding those with very young or heavily obscured star formation, from the MOSFIRE ...

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.

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.
