Mid- and far-infrared variability of PV Cep

Larionov, V. M.; Arkharov, A. A.; Di Paola, A. +4 more

We present the collection of all the mid- and far-IR observations (λ=3–170 µm) of the young eruptive variable PV Cep available so far in the literature. These data allow us to confirm that flux variability is a prominent feature at mid-IR wavelength (λ=3–25 µm). Color-magnitude plots clearly indicate that the observed variability is no…
