摘要：

B stars are the major members of the hot stellar objects with a range from about 2 to 20 M☉. Within a short lifespan down to 10 Myr, avariety of phenomena can be seen from some of them including permitted, forbidden line spectra and stellar pulsation. An unfolding beauty of these forbidden line emitter, also called B[e] star, is their unresolved stage of evolution. Additionally, pulsating cepheid variables are stars within a similar mass range with faithfully beating as an indication of luminosity/distance. Here, I introduce you to our journey from searching the stage of the B[e] stars to anchoring an galaxy by Cepheids in the M33.
