متن کاملThe time variation in infrared water - vapour bands in Mira variables ⋆
The time variation in the water-vapour bands in oxygen-rich Mira variables has been investigated using multi-epoch ISO/SWS spectra of four Mira variables in the 2.5–4.0 µm region. All four stars show H2O bands in absorption around minimum in the visual light curve. At maximum, H2O emission features appear in the ∼3.5– 4.0 µm region, while the features at shorter wavelengths remain in absorption...
