Resonance lines of C IV and N V form out to 316 solar radii in the wind of an O-type star, favoring a beta-law velocity exponent of 0.5 over the usual 0.8.
Speckle imaging of 81 RR Lyrae stars detects 10 likely bound companions at 20-220 AU separations, yielding a binary fraction estimate above 12 percent.
A ~1 solar-mass main-sequence star with supersolar metallicity has been traced back to the galactic center as a hypervelocity star ejected by the Hills mechanism.
Identifies 596 WD-MS binary candidates within 100 pc (497 new) by detecting NUV excess in Gaia sources and fitting SEDs to estimate WD temperatures and masses.
VLBA observations of Orion young stellar binaries yield Keplerian orbits and dynamical masses for four systems, with two showing agreement to SED-based estimates and one confirming an intermediate-mass star with nonthermal emission.
Monte Carlo tests with mock clusters show that fitting Gaia-like photometry with isochrones from different stellar codes produces biases of 0.6 to 1.5 in ΔY/ΔZ unless identical models are used for generation and fitting.
A new compact hierarchical triple main-sequence star system G1010 was discovered through combined low- and high-SNR spectroscopy, Gaia DR3 data, and TESS light curve analysis, showing an inner eclipsing binary rather than a compact object companion.
Discovery of NGC 7531-UCD1 as a tidally stripped ultra-compact dwarf in shell-like debris of NGC 7531, with photometric, spectroscopic, and N-body simulation support for a radial-orbit merger ~1 Gyr ago.
654 WD-FGK binaries cataloged with mostly low-mass hot white dwarfs formed via binary interactions.
Rotating stellar models initialized with observed velocity distributions yield modestly lower initial mass estimates for SN II progenitors than non-rotating models, with an upper limit of 20.4 solar masses.
