SDSS J100800.69+034332.0 - star with radio emission?

Rather intersting spectrum for QSO (sourcetype: QSO per SDSS ) ( or it is a star?? )
Or the source is behind the star? seems that the center of source is slightly to the right 😕

Intriguing! 😄
To me, the interactive SDSS spectrum of this star has no hint of anything other than normal K7 features (red is the model), but to an expert it might be otherwise. If there's something in the background - an AGN, say - it might (should?) show up in the WISE band 3 and band 4 images (K7 galactic stars would/should be invisible, in these bands, unless they have discs), but there seems to be nothing.
So, perhaps this is, in fact, a radio-active star? 😮

My knowledge of radio emission from stars is very limited. All I know is that they are rare (unless you have a supernova or a pulsar). I'll have to find someone to follow this up.

There is also a spectrum in DR6 available.: http://cas.sdss.org/dr6/en/tools/explore/obj.asp?id=588010358537126113
Specclass is also Star, but curiously it wasnt identified/classified as radiostar in following paper.:A Sample of Candidate Radio Stars in FIRST and SDSS

Maybe another such case, maybe not

I think this is a chance coincidence. They don't really line up within the errors. See FIRST contours over SDSSr below.

Yeah, that's what I thought
