Abstract
First orbits have been calculated for the visual binaries WDS 00090-5400, 01061-4643, 05248-5219 and 08447-5443 (Alzner & Argyle 2000; Argyle & Alzner 2000). The current period for the orbit of (Wierzbinski 1958) is too short to represent recent observations. The period has been lengthened to 450 years (Alzner & Argyle 2001). For 00090-5400 the period is 221 years with a moderate eccentricity; 01061-4643 is currently near periastron but is underobserved; 05248-5219 has passed periastron but there have been no observations since 1993. The visual component of WDS 08447-5443 (= $\delta$ Vel), which is not the same as the eclipsing component recently discovered by Otero (2000), has an unexpectedly short period.

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.
