Indexes in Enterprise Manager under "Table Info" tab

Does anyone knows what kind of indexes are the ones showing up under certain
tables in the "Table Info" tab? The indexes in question start with "_WA".
Also, I would like to know when they get created? and when are they being
used?It is my understanding that _wa objects are system created statistics.

They're auto statistics entries. Take a look at the space usage columns and
you'll see the value 0.
