SPHERE/ZIMPOL observations of 47 Cepheids detect companions in 17% of the sample, confirm known ones, reveal new wide components in three stars, and set 5-sigma contrast limits that exclude main-sequence companions more massive than late-K dwarfs beyond 0.5 arcsec for a subset.

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.
Dust depletion from UV spectra is associated with peaks in 3D extinction density maps to locate and chemically characterize local gas clouds at ~100 pc scales.
