Abstract

We carried out VLBI observations of SiO v = 2 and v = 3 J = 1 → 0 masers towards 12 long-period variables (LPVs) using four telescopes of the VLBI Exploration of Radio Astrometry (VERA) combined with the Nobeyama 45 m telescope. We found some correlation of the relative maser distributions with the stellar light curves. The location of the v = 2 masers coincide with the v = 3 masers region at pulsation phase ϕ = 0.0 − 0.2.
