Luminescent cometary continuum in spectra of comets 81P/Wild 2, 103P/Hartley 2, C/2009 K5 (McNaught), C/2009 P1 (Garradd) and C/2007 N3 (Lulin)
Abstract
Results of observations and study of middle-resolution optical spectra (λ/Δλ=1500 and λ/Δλ=15000) of comets 81P/Wild 2, 103P/Hartley 2, C/2009 K5 (McNaught), C/2009 P1 (Garradd) and C/2007 N3 (Lulin) are presented. The spectra were obtained with the echelle spectrograph and with the slit spectrograph installed on the 2-m Zeiss reflector of the High-mountain astronomical station of Institute of Astronomy of Russian Academy of Sciences and Main Astronomical Observatory of National Academy of Sciences of Ukraine at Terskol in 2009-2011 years. Luminescent cometary continuum level (nonsolar origin) in the spectra of comets was detected. Parameters of luminescent continuum were obtained. Substances that are luminophors in cometary atmospheres have been proposed. Peculiarities of luminescent continuum of these comets were discussed.
