Stellar infrared astronomy with EDISON
Space Science Reviews, 1992In this review the IR emission from circumstellar material is discussed, both of ionized gas and dust grains, and the astrophysical information that can be extracted from such observations. Some emphasis is placed on the possibilities of stellar IR astronomy using a large space-borne telescope, especially with respect to the much better spatial and ...

1972
The extension of astronomy in the wavelength region of 1 μ to 1 mm has in the past been limited by lack of detectors of high sensitivity and by the obscuration of the Earth’s atmosphere. Ground-based near infrared astronomy could be carried out within certain partial windows: i.e. from 2.1 μ to 2.4 μ, 3.5 μ to 4.0 μ, 4.6 μ to 4.7 μ, 8–13 μ, and 20–25 μ.
