Plasma Turbulence in the Lunar Environment Across Solar Wind and Magnetotail Conditions: Observations from Chandrayaan-2 Radio Science experiment

Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +1

The Moon's transit between the solar wind and Earth's magnetotail exposes the near-lunar environment to large and rapid variations in plasma density and flow structure. Two-way coh…

A study on the contribution of the interplanetary medium in radio occultation experiments

Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +4

Irregularities in electron density within the interplanetary medium (IPM) can cause fluctuations in the Doppler frequency of spacecraft radio signals. The amplitude of these fluctu…

A generalized method for estimating solar wind speeds and densities using spectral broadening for a Kolmogorov turbulence spectrum

Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +3

We present a unified method to derive both solar wind velocities and coronal electron densities in the near-Sun corona using Doppler spectral broadening of spacecraft radio signals…

A turbulence index independent framework for deriving solar wind speed and coronal electron density from radio spectral broadening

Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +3

We present a turbulence index independent framework for simultaneously deriving solar wind velocity and coronal electron density in the near-Sun region using the spectral broadenin…

On the estimation of solar wind velocity under varying solar activity conditions using Akatsuki measurements

Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +1

We present an analysis of solar wind dynamics based on Doppler spectral width measurements of X-band radio signals from the Japanese Akatsuki spacecraft. The dataset includes two s…
