The Slow‐Rotating Nucleus of Comet C/2013 R1 (Lovejoy)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.
