we propose to observe a number of bright be stars photometrically with isophot at 16, 25, 60, 90 and 160 micron to accurately establish the infrared energy distribution. these data will provide important information about the mass loss of these stars.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
