Discovery of detached post-Algol eclipsing binaries in the LMC with measured subgiant Roche-lobe fill factors of 73-89% that match the predicted TAMS contraction phase between Case A and Case AB mass transfer.
Secular chaos regulated by the inner-to-outer ZLK timescale ratio R enables high-eccentricity tidal migration in 3+1 systems at sub-critical inclinations, producing polar hot Jupiters.
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.
18-year monitoring finds stable metal line strengths and accretion rates in four of five polluted white dwarfs over hundreds to thousands of diffusion timescales.
Five new HI 21-cm absorption detections in LERGs and HERGs at z<0.5 reveal disturbed gas kinematics with velocity offsets over 350 km/s and a 3% detection rate consistent with lower-redshift samples.
Reanalysis of 79 solar twins indicates the Sun's chemical peculiarity is largely explained by Galactic chemical evolution, with 2-6 candidates possibly showing planetary engulfment.
New abundance measurements for NGC 6723 align its chemical patterns with other metal-intermediate globular clusters rather than indicating a transition to metal-rich properties.
New abundance measurements confirm two stars as r-II and one as borderline r-I, with r-process material older than 10 Gyr and possible links to the Thamnos structure.

Chemical abundances in the metal-intermediate GC NGC 6723
New abundance measurements for NGC 6723 align its chemical patterns with other metal-intermediate globular clusters rather than indicating a transition to metal-rich properties.
