Scientific paper
We present results of an ISOPHOT program (ISMAGB) dedicated to study the structure and infrared emission of interstellar matter surrounding red giants. This emission is detectable within about 2 pc of these stars, and the dust is heated to temperatures of 30-50 K, significantly warmer than the average temperature of diffuse ISM dust. In most cases, the dust mass within this volume is dominated by interstellar dust rather than circumstellar dust. We briefly present here the illustrating cases of R Aqr and μ Cep.
