Disk Detective Talk

Unknown thing that's bright in infrared.

  • Artman40 by Artman40

    While I was headbanging to William Herschel symphonies, I found this object. This looks like a star with something that can vaguely described as diffraction spikes. SED diagram also shows rather star-like figure with small error bars. However, this object peaks its brightness in K-band (2.16 ┬Ám). SIMBAD decides to stay silent when it comes to this object.
    What is this thing?

    NED shows a galaxy

    Interesting. What kind of a galaxy it might be?

    I think that NED is wrong in this case. Object seems more like a star than like a galaxy. At least to me.

    Yes the image and SED look like a star, but I can't get more info

    Guess it's time to wait for someone who knows more about this. I think if this had been a brown dwarfs of that apparent magnitude, it would have been already discovered.

    Well I am probably not the right scientist to answer these queries (as I am a theoretical astronomer), but this object could be a YSO disk with a huge NIR excess, possible a Herbig Ae. That said, this also looks to me like it could pass as an agn... which often give the same spectral signatures. C'est la vie! An interesting find nonetheless!
