Astronomical research web-log

Welcome to the web-log (AKA, blog) about my astronomical research. These articles are designed to complement the main pages of my web site in the following way:

• The articles are in time order (with a ATOM blog feed) and can therefore be used to see easily what I've been working on recently
• These articles should not generally be considered reference information, but rather work in progress. The main web-pages are the source of reference information
• These articles have a comment mechanism which may be used by visitors
• Some of the articles are simply commentary or pointers on others people work in astronomy and contain no original research
• Some of the material first presented in the articles may later get published in refereed papers or transferred to the main web-pages

Articles on this blog up to 8th March 2012 were originally hosted on the http://bnikolicresearch.blogspot.com/ site. They are now fully incorporated on these pages all new posts will be posted here.
