    Abstract: From an observational standpoint the Chant Meteor Procession of 9 February, 1913 is particularly remarkable, being especially noted for its long ground track of at least 15,000 km, and for the slow motion and near parallel to the horizon paths adopted by the meteors. The circumstances surrounding the Procession are re-considered here in terms of th... Show More

    Abstract: The purpose of this work to reproduces the flux of lines emitted by the ionized gas, resulting in a good agreement between observed and predicted line fluxes, temperatures and electron density with the chemical abundances of ionic species with carbon and oxygen rich planetary. The model has been calculated using clouds of dust grains in order to ca... Show More
