Spectroscopic confirmation establishes the first intermediate-age RR Lyrae star as a member of open cluster Trumpler 5, with velocity and [Fe/H] matching the cluster but some element depletions.

Detection of 17.26-day eclipses in KQ Puppis reveals it as a hierarchical triple with dynamical masses of ~10 M⊙ for the RSG and ~14 M⊙ for the inner pair, plus the first orbital parallax for any red supergiant.
RX Gru is a pre-main-sequence eclipsing binary with twin components of mass ~1 solar mass each, age ~28 Myr, and a circumbinary companion of minimum mass 89 Mjup in a 23.8-year orbit.
Synthetic spectra tests show Zeeman broadening recovers M dwarf magnetic field strengths more reliably with joint abundance fitting and WAIC selection than with free line strengths or BIC/AIC, which underestimate by 30-50% in active cases.
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.
Alpha-element distributions in Fornax, Sextans, Draco, and Carina correlate with galaxy luminosity while nitrogen-rich stars in Fornax suggest destroyed globular cluster relics.
JH 223 shows a 250 G dipolar magnetic field truncating its disk near corotation, with accretion columns warping the inner disk to produce 3.31-day periodic dips in brightness.

Testing the reliability of magnetic field strength measurements for M dwarfs
Synthetic spectra tests show Zeeman broadening recovers M dwarf magnetic field strengths more reliably with joint abundance fitting and WAIC selection than with free line strengths or BIC/AIC, which underestimate by 30-50% in active cases.
