K3V star the host of a bright triple?

  • JeanTate by JeanTate

    SDSS J170008.72+291903.7 has a position that's well within the resolution of FIRST source J170008.6+291904. And it's also pretty unambiguously a #triple. With nothing nearby (SDSS, photometrically).

    Yet it has an SDSS spectrum that is quite unambiguously that of a K3V star! 😮

    To quote myself

    http://arxiv.org/pdf/0906.3030v3.pdf

    Has this to say

    Resolved or complex radio morphology is typically associated with an extra-Galactic object such as a radio galaxy or quasar

    and

    Because these objects clearly show stellar spectra, we interpret them as optically-faint radio quasars in chance alignment with >bright foreground stars. We rejected the complex sources as obviously extra-Galactic

    still such almost perfect aligment ...

    Indeed. I had a vague feeling I'd seen this before, so thanks to your excellent memory, I now know that I had 😄
