KIC 8462852: THE INFRARED FLUX by Marengo, Massimo, Hulsebus, Alan, Willis, Sarah E.

“…We analyzed the warm Spitzer/IRAC data of KIC 8462852. We found no evidence of infrared excess at 3.6 μm and a small excess of 0.43 ± 0.18 mJy at 4.5 μm below the 3σ threshold necessary to claim a detection. …”

Sudden Extreme Obscuration of a Sun-like Main-sequence Star: Evolution of the Circumstellar Dust around ASASSN-21qj by Jonathan P. Marshall, Steve Ertel, Francisca Kemper, Carlos del Burgo, Gilles P. P. L. Otten, Peter Scicluna, Sascha T. Zeegers, Álvaro Ribas, Oscar Morata

“…The deep aperiodic dimming and absence of previous infrared excess are reminiscent of KIC 8462852 (“Boyajian’s Star”). The observed occultations are consistent with a circumstellar cloud of submicron-sized dust grains composed of amorphous pyroxene, with a minimum mass of 1.50 ± 0.04 × 10 ^−9 M _⊕ derived from the deepest occultations, and a minimum grain size of ${0.29}_{-0.18}^{+0.01}\,\mu {\rm{m}}$ assuming a power-law size distribution. …”
