The normalised spectra of the telluric standard taken at low and high air-mass values were com-bined with different weights to match the depth of the telluric lines in the Arcturus spectrum. Figures A.1, A.2, A.3, and A.4 show the rest-frame normalised spectra corrected for telluric absorption.
Aims.We investigate the infrared spectrum of Arcturus to clarify the nature of the cool component of its atmosphere, referred to as the CO-mosphere, and its relationship to the warm molecularenvelope or the MOLsphere in cooler M (super)giant stars.

ABSTRACT. A spectral atlas of the infrared spectrum of the bright K2 giant Arcturus has been completed using the 4-m Mayall telescope and FTS. The 0.9-5.3 ¡im spectrum of Arcturus was observed at high signal to noise with a resolution of 100,000. Telluric lines were removed by using telluric transmission spectra
1 Νοε 1995 · A spectral atlas of the infrared spectrum of the bright K 2 giant Arcturus has been completed using the 4 meter Mayall telescope and FTS. The 0.9-5.3 micron spectrum of Arcturus was observed at high signal-to-noise with a resolution of 100,000.
2 Ιουλ 2021 · Infographic showing the relationship between the continuous spectrum of a star whose light is shining on gas, the emission spectrum of glowing gas, and the absorption spectrum of that gas. The graphic is divided into two parts. The top half shows a light source, a light wave, and a cloud of gas.
The table below shows some of the characteristic absorption and emission lines of each star. You may not know where all of these elements have their emission lines. The chart below lists some of the more common ones and their approximate location in the electromagnetic spectrum.
