Surface-accretion disk models with fragile icy dust produce order-of-magnitude higher inner-disk water vapor enrichment and an anti-correlation between vapor concentration and residual gas mass.
Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
FICO procedure yields average precisions of 2.3% mass, 0.82% radius, 6.9% age and 0.49% mean density for 95 solar-like stars, outperforming direct frequency fitting for stars above 1.15 solar masses or 6050 K.
Numerical models of neutron star atmospheres from fusion ashes show a radiation-pressure layer limiting flux and absorption edges tied to chemical composition, with fits to diluted blackbodies plus edges for X-ray burst interpretation.
Population modeling of 50 tidally locked gas giants predicts cloud-driven evening-to-morning transit asymmetries reaching 500 ppm in optical bands for ultra-hot Jupiters, with regime-specific patterns from warm to ultrahot climates.
Segmenting EST into smaller subapertures reduces wavefront errors from high-altitude seeing, allowing higher-quality restored spectropolarimetric data before MCAO becomes available.
tPIC2.2 supplies a list of 217,741 stars for PLATO's LOPS2 field, including 202,315 FGK dwarfs/subgiants and 15,037 M dwarfs with uniformly estimated temperatures, radii, and masses.
Cosmic rays heat inner gas clouds in NGC 5728 and boost low-ionization optical and certain mid-IR lines while high-ionization lines remain insensitive, enabling multi-wavelength separation of CR, shock, and metallicity effects.
High CR ionization rates (above 10^-13 s^-1) in AGN and starburst models produce enhanced low-ionization emission that matches observations without super-solar metallicities and suggests revised BPT diagram boundaries.
Catalog of [Cr/Fe], [Co/Fe], [Ni/Fe] abundances for 4113 stars in globular clusters and dwarf galaxies derived from Keck/DEIMOS medium-resolution spectra with reported median uncertainties.

Heavy element enrichment of gas in surface-accretion disks: A possible origin of the mass-metallicity anti-correlation in exoplanets
Surface-accretion disk models with fragile icy dust produce order-of-magnitude higher inner-disk water vapor enrichment and an anti-correlation between vapor concentration and residual gas mass.

Origin and evolution of NiI and FeI in the coma of the interstellar comet 3I/ATLAS throughout its trajectory
Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
