$data is an object of model class having single row of data. author is a relation to another model of the model whose instance is $data. $data->author->username Here username is a variable of the model whom author points. $data->author also treated as an object. It will just execute a relational query to the model whom author points.

You can see the relations of the model in relations() function of the model. Try out guide of yii you will find your answer.

See documentation for CListView:

The above code first creates a data provider for the Post ActiveRecord class. It then uses CListView to display every data item as returned by the data provider. The display is done via the partial view named '_post'. This partial view will be rendered once for every data item. In the view, one can access the current data item via variable $data. For more details, see itemView.

So in your context, $data is the Post being rendered.
