Abstract:

Several H I related astrophysical parameters such as neutral hydrogen total mass and hydrogen mean projected density, indicative total mass as well as usual ratios $M_{{\rm H}}/L_{0}$ , $M_{{\rm H}}/M_{{\rm i}}$ and $M_{{\rm i}}/L_{0}$ for 23 galaxies from Kazarian lists are derived. Their variation ranges are rather wide almost coinciding with those for normal galaxies belonging to the same morphological types. Kazarian galaxies do not constitute a homogeneous sample by any of the commonly used H I related parameters. Comparison with Markarian and blue Haro galaxies demonstrate that Kazarian galaxies have quite similar H I properties and contain rather high relative numbers ( $\approx30\%$ ) of peculiar objects. Brief comments on the peculiar galaxies Kaz 63, Kaz 65, Kaz 69 and Kaz 211 are given.

Key words: UV-excess galaxies -- Kazarian galaxies -- hydrogen content

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.
