Update 3/22: Tyler Ellis, an astronomy graduate student working with Tabetha Boyajian, updated Gizmodo via email this weekend to let us know that the follow-up response has so far been “pretty extensive.” For photometry (counting light particles being emitted in different parts of the electromagnetic spectrum) observers at the Los Cumbres Global Observatory and the KELT planet hunting network are viewing the star in optical, while the SWIFT ultraviolet space telescope, the Subaru telescope, and the Large Binocular Telescope are studying its infrared glow. Other collaborators are doing spectroscopy, trying to figure out which areas of the spectrum, exactly, are dimming. Still others are attempting to measure the polarization of light emitted by Tabby’s star, which can help determine whether the dimming is caused by something in the interstellar medium.
