Water Around the Protostar AFGL 2591
Date
Spectra of protostar AFGL 2591 and standard star Vega from 6.085 to 6.130 microns, superimposed. This specific wavelength range is not observable from any ground-based observatory. The strong absorption lines (wavelengths with low intensity) appearing in both spectra are caused by water vapor in Earth’s atmosphere.
