First reported seismic detection of an internal magnetic field reaching approximately 4 kG in the radiative envelope of the gamma Doradus star KIC 2309579 using the variable delta Ka sensitive to Kelvin gravito-inertial modes.
Using occultation-derived sizes and Herschel thermal data, the study identifies three previously unknown likely binary TNOs and reports satellite size estimates while confirming no sizable satellites are needed for three others.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
ALMA CO(3-2) observations with MCMC retrievals show latitudinal temperature trends on Neptune, including a cold southern polar layer at 300-600 mbar, consistent with Voyager at 10-100 mbar but new at deeper levels.
Eccentricity posteriors of dynamically captured binaries can be mapped to capture parameters and compared against environment velocity distributions to constrain host and infer decay time.
GJ 1132 b is estimated to have received at least 50 times the cumulative XUV flux of modern Earth with over 95% probability across models, supporting its classification as an atmosphere-free world.
SHAMe-SF modeling of small-scale DESI ELG clustering delivers 6% precision on σ8 and Ωm h², matching full DR1 results with 1% volume.
Reassessment of 12 TTV claims finds only two systems with compelling unique solutions for the perturbing planet, six with multiple viable solutions, and two with weak evidence overall.
dynesty is an open-source Python package for dynamic nested sampling that improves efficiency in Bayesian posterior and evidence estimation compared to MCMC on certain problems.
BAGPIPES fitting of 9289 massive quiescent galaxies shows most SFHs rise gradually then quench in 1-2 Gyr, with faster quenching at z>1 and slower at z<1, interpreted as multiple AGN feedback and gas-supply mechanisms.
Validates redshift-space power spectrum and bispectrum analysis on Abacus-PNG mocks to recover unbiased f_NL constraints for Euclid spectroscopic sample.
Lunar impact flashes on highlands exhibit longer and shallower decay than on maria, with the dual-size ejecta model attributing the difference mainly to fine droplets and indicating lithology dependence in early cratering.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
A centered swept-back multipolar magnetic field up to octupole order reproduces the bolometric thermal X-ray light curve of MSP J0030+0451.
TOI-1710 b has a true obliquity of 149 degrees indicating retrograde motion, favoring high-eccentricity migration via planet-planet scattering and Kozai-Lidov cycles for this tidally detached super-Neptune.
A transit search on TESS Cycle 1 full-frame images produced 10,091 new planet candidates down to T=16 mag, more than doubling the known TESS total, with one hot Jupiter confirmed by radial velocity.
Ca-rich gap transients and 91bg-like SNe occupy similar massive quiescent host parameter space with peak delay times around 10^4 Myr, unlike normal Type Ia (~10^3 Myr) and Type II (~10 Myr) SNe.
COLIBRE calibrates supernova and AGN feedback parameters in multi-phase ISM cosmological simulations using emulator-based fitting to reproduce the z=0 galaxy stellar mass function and size-stellar mass relation at three resolutions.
No significant environmental dependence is found for the galaxy size-mass relation at low redshift across clusters, voids, cluster masses, and cluster-centric distances.
A modified ellipsoidal modulation model with precessing disk irradiation effects revises the SMC X-1 pulsar mass to approximately 1.35 solar masses.
TOI-159 b is confirmed as the hottest known eccentric hot Jupiter (e = 0.24) with a 13-sigma Keplerian detection around a young gamma Doradus star, including a preliminary low-resolution transmission spectrum.
Comparison of Galactic magnetic field models to polarized synchrotron observations shows good agreement on angles but poor match on intensity, indicating local foreground structures must be incorporated.
