Native-resolution retrievals on 0.97-5.27 micron JWST spectra of VHS 1256 b find a ~79% cloud deck, solar-like metallicity and C/O, and depleted 18O in a partially cloudy disequilibrium atmosphere.

A 6D kinematic census identifies 18 anomalous Cepheids with extreme orbits, including one possibly scattered by globular cluster E3, and finds consistency between dynamical and stellar ages.
A new redshift-correlation technique with third-generation GW detectors can constrain the BNS contribution to cosmic r-process nucleosynthesis to 5-6% precision via Fisher forecasts on mock bright- and dark-siren data.
A new PSF-fitting tool extracts TESS light curves for 91 SMC massive stars, revealing binarity, pulsations, and SLF variability whose morphology tracks HR diagram position similarly to Galactic stars.
A neural network trained on simulations infers stripping times for Sagittarius stream stars from phase-space data, measuring a 0.3 dex/Gyr metallicity gradient and estimating ages for globular clusters such as Pal 12 and NGC 2419.
AGILE archival data reveal gamma-ray flares from a source matching IGR J17354-3255, with orbital phase correlation supporting physical association and high-energy emission from SFXTs.
Type Ib supernovae are systematically bluer than Type Ic supernovae in optical colors, likely due to helium-rich versus helium-poor progenitors.
Panchromatic JWST spectrum of WASP-121 b detects SiO and measures refractory-to-volatile ratios 3x stellar, consistent with mixed solid-gas accretion or migration with continued solid accretion.
Spectroscopic measurements confirm a tight 6D phase-space clump of four RGB stars as part of the distant southern spur of the Sagittarius stream, likely stripped from Sagittarius's halo in the earliest interaction phases.
Radio observations of Faraday rotation in CARLA J1510+5958 at z=1.72 yield a lower limit of 0.4 μG on the average magnetic field strength in the proto-intra-cluster medium.
Bar-induced migration can move ω Cen from the GSE phase-space region, but requires Ω_b ≲ 26 km s^{-1} kpc^{-1}, challenging consensus on the bar speed.
JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
High-contrast imaging with PACO and REXPACO reveals a new candidate companion at ~14 au and a tightly wound H-alpha spiral in the inner disk of HD 142527, suggesting ongoing companion-disk interactions.
Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.
A new SPHEREx-based spectral library doubles the sample of ultracool dwarfs with 0.75-5.0 micron spectrophotometry to 7402 objects and provides automated typing tools.
FUor masses inferred from Keplerian line broadening in H-band spectra match the solar neighborhood IMF, indicating a universal eruptive phase during star formation.
Radial velocity data reveal a 310-day orbital period in NaSt1 with opposing phases in two groups of emission lines, supporting its nature as a post-mass-transfer massive binary system.
New high-resolution spectra yield abundances for 7 neutron-capture elements in open cluster stars, revealing flat Milky Way gradients for second-peak s- and r-process species and shallower slopes for first-peak s-process.
Simulations show Lindblad-resonance wrinkles from non-winding spirals are filled with zero-age stars on orbits normally occupied by much older populations, offering an age-based constraint on past transient spiral patterns.
Generates and publicly releases 81,498 detrended Kepler light curves plus a catalog of 87 periodic variables (26 new) in the 2.5 Gyr cluster NGC 6819 using Gaia DR3 for membership.
Gaia-HELIX is a new catalogue of 28,394 bona-fide Hα emitters identified in Gaia DR3 XP spectra, after removing 95% of initial candidates that were M-type star mimics.
Gaia-derived parameters for 13 Orion clusters fed into N-body simulations reveal two regimes: seven with α_vir ≲ 7 retain bound cores for ≳170 Myr while six with α_vir ≳ 7 dissolve before 120 Myr.
First blind optical identification of a z=0.153 sub-luminous GRB afterglow with Ic-BL SN, yielding a volumetric rate consistent with on-axis high-luminosity long GRBs.
Catalog of 1,573 molecular clouds with robust distances from 150 to 3000 pc determined by matching CO intensity maps to dust extinction maps, 90% measured for the first time with ~20% statistical and ~10% systematic uncertainties.
