The eRASS1 data release catalogs nearly 930,000 X-ray sources from the first six months of the eROSITA survey, increasing known sources by over 60% and resolving 20% of the 1-2 keV cosmic X-ray background.
Spectroscopic monitoring detects phase-locked flares to Proxima d and flare-intensity modulation by Proxima b, producing a -16 G polar field estimate for the inner planet via Poynting-flux modeling.
Four transiting sub-Neptunes with radii measured to <1.7% precision and masses >3 sigma for three planets, plus an outer non-transiting companion, discovered around TOI-5624 via TESS, CHEOPS photometry, and ground-based RV data.
Deep learning reanalysis of the SHINE F150 sample recovers known companions and identifies 13 new substellar candidates, three of which are photometrically promising with one strong follow-up target.
The RRc star IY Lyr shows a 3.94-year orbital wobble consistent with a ~1.37 solar-mass compact companion, likely a neutron star, and is claimed to be the first such system found in the Galactic thick disk.
Simulations show Plato can recover relativistic photometric signatures of supermassive black hole binaries in bright quasars (G≤18) via Bayesian inference on mock light curves.
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.
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.
A gradient boosted classifier on X-ray light curve features detects stellar flares at 97.1% test accuracy and generates the largest public catalog of such events.
Sco-Cen shows abrupt jumps and plateaus in velocity dispersion correlated with star formation bursts, indicating isotropic expansion, inside-out propagation at 5-6 km/s, and stellar feedback as the primary driver.
New C, N, O, S, K, Cu abundances for 714 solar-neighbourhood stars show that ratios relative to oxygen discriminate thin- and thick-disk populations more clearly than traditional [X/Fe] trends.
IZ Tel and UW Vir are oEA binaries with δ Sct primaries showing mass transfer, derived masses of 1.48/0.33 and 2.39/0.67 solar masses, and multi-frequency pulsations including combination modes.
