Observational Study and Analysis of Point Sources Found by the Infrared Astronomy Satellite
Abstract
Results are presented of studies of the space distribution and other properties of two significant classes of compact astrophysical sources which are bright at midinfrared wavelengths: stars with excess infrared emission due to heated dust, and galaxies with nuclei that heat surrounding dust to anomalously high temperatures. The stellar studies reveal a complex structure for the galactic disk, which must be taken into account in the development of realistic infrared sky models. The extragalactic studies have been temporarily stalled by the remarkable discovery of low-luminosity stars with strong far-infrared spectral energy distributions mimicking warm galaxies Much further observational work is needed to understand the origin of this emission.
