[vsnet-newvar 753] IRAS08005-2356 = TmzV429

[Taichi Kato <tkato>]

IRAS08005-2356 = TmzV429

   I noticed that the Takamizawa variable TmzV429 is identical with
the proto-planetary nebula (PPN) IRAS 08005-2356 (ref. Slijkhuis et al. 1991,
A&A 248, 547).  This is probably the first-ever demonstration of
the detection of PPN variability by Takamizawa's variabile star survey.
The spectrum is F-supergiant.  Together with Takamizawa's observations,
the object seesm to be classfied as an (high luminosity) SRD-type variable.
Slijkhuis et al. 1991 reported that Te Lintel Hekkert et al. (1991)
reported a possible brightening by a several tenths of magnitude since
1986.  This possible variation seems to be more likely attibuted to
shorter time-scale variations discovered by Takamizawa.
