IR Imaging of SN1987A

Résumé

We present IR imaging observations obtained at various phases in the evolution of SN1987A. They have been obtained with ground-based telescopes in Chile. Some of the early and late ones have not been shown before. Particular emphasis is placed on the recently resolved mid-IR images showing dust in the inner ring being heated by the interaction with the ejecta. Some of its properties are elaborated as well as the importance of such observations now and in the future. Attention is also drawn to the IR emission from the central ejecta and its behaviour. Temporal variations are highlighted.
