Tentative detection of a 21.8-day SB1 around V0885 Per that could set a new record for the shortest outer orbit in a compact hierarchical triple, but poor spectra quality prevents confirmation of physical association.
Differential reddening across the field, not rotation, drives the extended main-sequence turn-off in NGC 1647, whose age is 203 million years from lithium measurements.
Revised solar photospheric abundances yield Z/X = 0.0187 with C, N, O at 8.46, 7.83, 8.69, preserving the solar modeling discrepancy and revealing a modest volatile-refractory offset from CI chondrites.
LAMOST J052016.79+345651.7 is an EW contact binary with warm ionized gas from shock-driven outflows, cold circumstellar dust causing IR excess, and an evolutionary path toward a blue straggler via mass loss.
From LAMOST DR12, 504 classical Be stars are cataloged with 141 new, 14 RV-variable binaries, 60 RUWE-based candidates, 34 cluster members, and 37 runaways.
