In this part of the electromagnetic spectrum, the continuum ‘optical’ radiation is usually fairly close to a blackbody.

After more reading, I now know that the text here refers to “effective temperature”, which as best I can tell is the temperature a black body would have to be to emit the star’s radiation.
