| dc.description | We discovered that GSC 6554.559 is a previously unknown variable star, and named as TmzV429. We noticed that TmzV429 is identified with the IRAS-selected proto-planetary nebula (PPN), IRAS 08005-2356, which is undergoing a vigorous mass-loss episode. The analysis of photometric data suggests that TmzV429 a short-period pulsator, resembling a high-latitude yellow supergiant variable. TmzV429 is considered to be one of rare objects caught in the rapid course of PPN evolution, and shows one of the most striking mass-loss features among variable stars in the PPN stage. Since its evolutionary time-scale is estimated to be quite short (~150 yrs), future observations of pulsations of TmzV429 is expected to provide an excellent opportunity to study the stellar evolution in real time. | |
