We present Spitzer observations at 3.6 and 4.5 μm of the supernova SN 2011dh (PTF 11eon) in M51 from 18 days to 625 days after explosion. The mid-infrared emission peaks at 24 days after explosion at a few ×107 L , and decays more slowly than the visible-light bolometric luminosity. The infrared color temperature cools for the first 90 days and then is… CONTINUE READING
