Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light and radio, which radiates from stars and other celestial objects.
Bengt Edlén (2 November 1906, Gusum – 10 February 1993, Lund) was a Swedish professor of physics and astronomer who specialized in spectroscopy.
Charles Augustus Young (December 15, 1834 – January 4, 1908) one of the foremost solar spectroscopist astronomers in the United States, died of pneumonia after a brief illness, at his home in Hanover, New Hampshire, on 4 January 1908.
A chemical element is a species of atoms having the same number of protons in their atomic nuclei (that is, the same atomic number, or Z).
A corona (Latin, 'crown') is an aura of plasma that surrounds the Sun and other stars.
Dmitri Ivanovich Mendeleev (a; 8 February 18342 February 1907 O.S. 27 January 183420 January 1907) was a Russian chemist and inventor.
Highly charged ions (HCI) are ions in very high charge states due to the loss of many or most of their bound electrons by energetic collisions or high-energy photon absorption.
Iron is a chemical element with symbol Fe (from ferrum) and atomic number 26.
In the late 19th century, luminiferous aether or ether ("luminiferous", meaning "light-bearing"), was the postulated medium for the propagation of light.
Nebulium was a proposed element found in astronomical observation of a nebula by William Huggins in 1864.
Nickel is a chemical element with symbol Ni and atomic number 28.
A total solar eclipse occurred on August 7, 1869.
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
Spectroscopy is the study of the interaction between matter and electromagnetic radiation.
Walter Robert Wilhelm Grotrian (21 April 1890 in Aachen; † 3 March 1954 in Potsdam) was a German astronomer and astrophysicist.
William Harkness (December 17, 1837 – February 28, 1903) was an astronomer, born at Ecclefechan, Scotland, a son of James (1803–78) and Jane (née Wield) Harkness.
