Abstract
Context. Both 22 GHz water and 6.7 GHz methanol masers are usually interpreted as signposts of early stages of high-mass star formation but little is known about their associations and the physical environments in which they occur. Aims: We attempt to derive accurate positions and morphologies of the water maser emission and relate them to the methanol maser emission mapped earlier with Very Long Baseline Interferometry. Methods: We searched for 22 GHz water masers in 31 methanol maser sources was searched for 22 GHz water masers using the VLA and observed in the 6.7 GHz methanol maser line with the 32 m Torun dish simultaneously. Results: Water maser clusters are detected towards 27 sites leading to the identification of 15 new sources. The detection rate of water maser emission associated with methanol sources is as high as 71%. In a large number of objects (18/21), the structure of water maser is well aligned with that of the extended emission at 4.5 μm confirming the origin of water emission in outflows. The sources of methanol emission with ring-like morphologies, which likely trace a circumstellar disc/torus, either do not show associated water masers or the distribution of water maser spots is orthogonal to the major axis of the ring. Conclusions: The two maser species are generally powered by the same high-mass young stellar object but probe different parts of its environment. The morphology of water and methanol maser emission in a minority of sources is consistent with a scenario where 6.7 GHz methanol masers trace a disc/torus around a protostar while the associated 22 GHz water masers arise in outflows. The majority of sources in which methanol maser emission is associated with the water maser appear to trace outflows. The two types of associations may be related to different evolutionary phases.

Distribution of sources in all sky (l,b)

Distribution of sources in all sky using Aladin

Tip: Click on some source to get more informaiton

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
