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.

Six seismic solar analogs have masses 0.91-1.04 solar masses, radii 0.95-1.08 solar radii, and ages 1.8-9.1 Gyr, with one star matching the Sun closely enough to be called a solar twin.
