Query: Near-Infrared observations of the type Ib Supernova SN2006jc: evidence
  of interactions with dust   In the framework of a program for the monitoring of Supernovae in the
Near-Infrared (NIR) carried out by the Teramo, Rome and Pulkovo observatories
with the AZT-24 telescope, we observed the Supernova SN2006jc in the J,H,K
photometric bands during a period of 7 months, starting ~36 days after its
discovery. Our observations evidence a NIR re-brightening, peaking ~70 days
after discovery, along with a reddening of H-K and J-H colors until 120 days
from discovery. After that date, J-H seems to evolve towards bluer colors. Our
data, complemented by IR, optical, UV and X-ray observations found in the
literature, show that the re-brightening is produced by hot dust surrounding
the supernova, formed in the interaction of the ejecta with dense circumstellar
matter.
