Shestakova L. I., Serebryanskiy A. V., Krugov M. A., Aimanova G. K., and Omarov Ch. T. Signs of Emissions of Alkali Metals Na I, Li I, and K I During First Minutes After DART Probe Crash on Dimorphos. // Research Notes of the AAS. – 2022. – Vol. 6, N 10, P.223. – DOI: 10.3847/2515-5172/ac9d33
We present the results of the analysis of spectral observations taken a few minutes before, at the time, and in the first minutes after the impact of the DART probe on the asteroid Dimorphos. Our analysis showed signs of Na I, Li I, and K I alkali metal emissions appearing at the time of the impact and for several minutes after it.
