Abstract
We have carried out almost simultaneous observations of H2O and SiO (J = 1-0, v = 1) masers for 171 known late-type maser stars with the 34 m radio telescope at Kashima. We found a systematic change in the H2O maser spectra related to the evolution of the stars. Typically, H2O maser spectral profiles are singly peaked in Mira variables, but doubly peaked in IRC/AFGL objects and OH/IR stars. The expansion velocity of H2O masers increases with decreasing IRAS color temperature. This is explained by the shock excitation model proposed by Cooke and Elitzur (1985). The blue shifted peak in the profiles is more prominent than the red shifted peak in most of the IRC/AFGL objects and OH/IR stars. A blocking model of the redshifted peak is introduced.

Distribution of sources in IRAS color-color diagram

Tip: Use "Box select" or "Lasso select" to display colour-selected sources in Aladin all-sky view

Tip: Click on some source to look at the different surveys. You must select some surveys in previous page at "View images"

Original color diagram is taken form van der Veen & Habing (1987)

Type	Description
I	Oxygen-rich non-variable stars without circumstellar shells
II	Variable stars with "young" O-rich circumstellar shells
IIIa	Variable stars with more evolved O-rich circumstellar shells
IIIb	Variable stars with thick O-rich circumstellar shells
IV	Variable stars with very thick O-rich circumstellar shells
V	Planetary nebulae and non- variable stars with very cool circumstellar shells
VIa	Variable stars with relatively cold dust at large distances; a significant part of the stars is carbon-rich
VIb	Variable stars with relatively hot dust close to the star and relatively cold dust at large distances; Some of the objects have proven to be O-rich
VII	Variable stars with more evolved C-rich circumstellar shells
VIII	Different sort of objects
