Arclite Theme – Remove Sidebar Rss Categories?

This is the theme I use: http://ww.wp.xz.cn/extend/themes/arclite

This is the site http://www.staroversky.com

On the top right side you will see RSS feeds generated for each category that I have. How do I remove them properly?

I assume it has to do something with sidebar.php? Somewhere here:
