From: Newly formed dust within the circumstellar environment of SN Ia-CSM 2018evt

Extended Data Fig. 4: The optical and MIR light curves of SN 2018evt.

Panel (a) The BV gri band light curves of SN 2018evt. Panels (b) and (c) present the ~ 3.5 μm (Spitzer CH1 and NEOWISE W 1) and ~ 4.6 μm (Spitzer CH2 and NEOWISE W 2) photometry of SN 2018evt, respectively. Black-solid lines show polynomial fits to the light curves before and after day +310. The MIR light curves of several other SNe Ia-CSM at similar phases are shown for comparison, including SNe 2002ic, 2005gj35, PTF11kx69, 2012ca, 2013dn31,71, and 2020eyj72. The error bars shown represent 1 - σ uncertainties of magnitudes.
