Blue straggler stars in old open clusters exhibit a Kraft break in rotation, with rapid rotators above the break and slow rotators below, indicating their envelopes behave like those of single stars.
Spectroscopic members of the M92 stream yield a Milky Way bar pattern speed of 29.1 +0.7/-0.4 km s^{-1} kpc^{-1}.
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.
Reconstruction of GCIMF from present-day systems via environment-dependent mass-loss inversion yields power-law high-mass ends whose slopes correlate with host halo mass.
Blue straggler stars in old open clusters predominantly appear near the terminal-age main sequence because mass transfer from asymptotic giant branch donors enriches their cores with helium.
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.
Using Gaia data on 79 globular clusters, a new C_index ranks clusters by radial and kinematic substructure and finds no sign of artificial phase-space structures, only a few known-dynamically-complex outliers.
Dynamical dissolution of soft primordial binaries fully explains observed main-sequence binary fractions in globular clusters under solar-neighborhood initial conditions.
BonFIRE and CampFIRE simulations show bursty clustered star formation in early galaxies and predict UV luminosity functions matching observations at faint magnitudes with a turnover at M_UV approx -14 but overpredicting brighter galaxies.
New SBF distance confirms NGC5846_UDG1 lies in the NGC 5846 group and reconciles prior GC counts to ~50 members, supporting a massive dark matter halo.
Photometric metallicities for 367k stars in Omega Centauri reveal no significant gradient within the half-light radius and well-mixed stellar subpopulations.
