Photographic Infrared Spectroscopy and Near Infrared Photometry of Be Stars: (Review Paper)
Published online by Cambridge University Press: 14 August 2015
Extract
As the title indicates two topics will be tackled in this presentation: spectroscopy and photometry. Let us therefore define first what ‘infrared’ means for these two subjects. I chose the following definitions:
– photographic infrared spectroscopy: wavelengths Hα ≤ λ < 1.2 μ
– near infrared photometry: wavebands: 1.6 μ ≤ λ ≤ 20 μ
