New VLT observations of He I* absorbers yield a primordial ³He/⁴He ratio of (1.15^{+0.24}_{-0.21})×10^{-4} consistent with standard Big Bang nucleosynthesis, plus an updated stellar yield scaling factor.
Bulge Fossil Fragments are estimated to generate 15-250 times more binary black hole mergers than typical globular clusters, marking them as a new class of gravitational wave sources.
Multi-element Bayesian modeling of 23 EELGs reveals short depletion timescales and large mass-loading factors in a burst-driven regime, with abundance ratios isolating star-formation efficiency, outflows, and inflows.
Reanalysis of 79 solar twins indicates the Sun's chemical peculiarity is largely explained by Galactic chemical evolution, with 2-6 candidates possibly showing planetary engulfment.
GALEX NUV excess shows an 8 sigma anti-correlation with [Fe/H] in 492 halo stars, enabling distinction of VMP stars but limited for EMP stars by chromospheric variability.
