Optimized filters centered at 3920-3960 Angstrom yield metallicity estimates with 0.18-0.39 dex precision down to [Fe/H] ~ -4 for metal-poor stars from Gaia XP spectra, enabling a catalog of 14.5 million such stars.

Negative Ca II IRT residual indices in FGK stars arise mainly because synthetic photospheric templates miss chromospheric structure and NLTE effects that deepen the observed cores.
Observational study of 290 exoplanet-host stars finds higher C, O, S, Fe, Ni abundances in giant-planet hosts than small-planet hosts, with C/O ratios, hot/warm differences, and mass correlations that vary by subpopulation.
Three massive planets detected around HD125136 (2.26 MJup, 850 d) and HD127195 (0.66 and 0.78 MJup, 535 d and 834 d) via Bayesian Keplerian modeling of CORALIE RV series; one additional signal attributed to activity.
Resolves six speculative companions into one giant planet, one eccentric brown dwarf, two low-mass stars, and two stars with no detectable companions.
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.
Empirical zero-point constants for Gaia bolometric corrections are derived as weighted averages 0.8677, 1.0449, and 2.0510 mag for G, GBP, and GRP from 88 stars, yielding corresponding magnitude zero-points via IAU definitions.
X-ray data from V834 Tau, LQ Hya, and BY Dra show two-temperature quiescent coronae with iron depletion and six superflares, with recurrent events on LQ Hya suggesting stable magnetic structures.
