A PN in a 90 Myr M31 cluster is associated via position and velocity, implying a 5.66 solar mass progenitor with nitrogen enhancement.
CRIRES+ spectra of 30 RGB stars in Liller 1 reveal multi-metallicity sub-populations with abundance trends matching the bulge field and Terzan 5, indicating in-situ formation rather than globular-cluster origin.
TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.
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.
N6946-BH1's remnant is roughly 10 times fainter than its progenitor while stellar merger remnants are 10-100 times brighter, and asymmetric dust cannot explain the difference.
Axisymmetric self-consistent models fitted to NSD kinematic data yield a mass of 1.05 x 10^9 solar masses, radial scale length ~89 pc, vertical scale ~28 pc, and declining velocity dispersion.
A homogeneous catalogue of age, [Fe/H], heliocentric distance and E(G_BP-G_RP) for 5056 open clusters is produced from uniform Bayesian nested sampling of Gaia DR3 CMDs against PARSEC isochrones with physically motivated priors.
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.
Simulations indicate the Vera C. Rubin Observatory can optimally localize nearly all observable galactic supernova neutrino triggers and has a 57-97% chance of catching the optical supernova.
A millimeter survey detects disks around five Herbig Be stars and shows no evidence of rapid disk dissipation with increasing stellar mass.
SED analysis of blue stragglers in open clusters finds UV excesses indicating hot degenerate companions in 15 of 35 candidates, supporting binary evolution.
