The Astrophysical Journal
The reason for the changes were given by the society as the increasing financial demands of the University of Chicago Press.[7] Articles accepted after October 11, 2022, will be published under the Creative Commons license CC-BY-SA 4.0.[9] In addition to the two founding editors, there was an international board of associate editors: M. A. Cornu, Paris; N. C. Dunér, Upsala; William Huggins, London; P. Tacchini, Rome; H. C. Vogel, Potsdam, C. S. Hastings, Yale; A.[10] It was intended that the journal would fill the gap between journals in astronomy and physics, providing a venue for publication of articles on astronomical applications of the spectroscope; on laboratory research closely allied to astronomical physics, including wavelength determinations of metallic and gaseous spectra and experiments on radiation and absorption; on theories of the Sun, Moon, planets, comets, meteors, and nebulae; and on instrumentation for telescopes and laboratories.[10] The further development of ApJ up to 1995 was outlined by Helmut Abt in an article entitled "Some Statistical Highlights of the Astrophysical Journal" in 1995.
