Implication of the period-magnitude relation for massive AGB stars and its astronomical applications

Akiharu Nakagawa, Tomoharu Kurayama, Hiroshi Sudou +1

We present astrometric very long baseline interferometry (VLBI) studies of AGB stars. To understand the properties and evolution of AGB stars, distances are an important parameter.…
