AN INFRARED NEBULA ASSOCIATED WITH δ CEPHEI: EVIDENCE OF MASS LOSS?

We present the discovery of an infrared nebula around the Cepheid prototype δ Cephei and its hot companion HD 213307. Large-scale (~2.1 × 10[superscript 4] AU) nebulosity is detected at 5.8, 8.0, 24, and 70 μm. Surrounding the two stars, the 5.8 and 8.0 μm emission is largely attributable to polycyc...
