Coronal radio sounding experiment results for solar wind flow speeds from the Indian mars orbiter mission

Abstract

The complexity of the solar wind near the sun was shown by the first radio signal measure ments taken by a space probe. The oscillations in radio frequency that are recorded during conjunction can provide information about the turbulent plasma that is present in the solar wind. Radio occultation is a technique that was employed in 1965 by the Mariner IV space craft to estimate the atmosphere of Mars. This method involves detecting changes in the phase, frequency, and amplitude of radio signals as they pass through the atmosphere. In this thesis, we demonstrate how the Doppler method can be utilized to study the solar corona and wind by showing how it may be applied in various contexts. This investigation will collect data from October 2, 2021, all the way through October 14, 2021, and the heliocentric distance will range between 5 and 9 Rodot over the whole observation period. The range of velocities that can be attained for the given parameters of distance and time is 112-260 kilometers per second. Comparing electron number density models from earlier research with profiles made in Octo ber 2021 using data acquired by the Indian DSN during the Indian MOM is a part of our work. These profiles were created using data obtained by the Indian DSN during the Indian MOM.
