Abstract
We have obtained infrared images in the J, H, and K bands of the field containing the post-AGB final-flash object V605 Aql. V605 Aql is the central star of the planetary nebula A58 but has been incorrectly identified with other stars in this field. In the infrared images V605 Aql appears as a very red star at the position of the A58 center. We present JHK photometry on two dates as well as astrometry of V605 Aql. The infrared light from V605 Aql originates in a thick dust cloud surrounding the star. There is no indication of variability over a three month time period.

Key words: stars: evolution -- stars: individual: V605 Aql -- stars: AGB and post-AGB -- planetary nebulae: individual: A58 -- infrared: stars

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
