The decay phase of the SEP event after the maximum contains information about solar wind velocity, turbulence of the IMF, and other parameters of the
interplanetary medium. The level of disturbance of IMF is one of the main factors of the state of
interplanetary medium characterized by the diffusion coefficient of particles in the medium, and the solar wind velocity determines the form of temporal profile of particle flux, the rate of its increase, and decay after maximum.
"Since other researchers have established how fast the carbon moves away from the comet, we could use the fall-off of the light as a function of distance to measure how long the carbon lives in the
interplanetary medium before it is ionized," said Morgenthaler, lead author of a recent paper on the topic that appeared in the Astrophysical Journal.
The 118 papers cover the sun, planets, and the
interplanetary medium; our galaxy's stars, exoplanets, and the interstellar medium; extragalactic astrophysics and cosmology; dynamical astronomy and relativistic astrophysics; astronomical infrastructure, and history and education in astronomy.
In Chapter 28 he talks about the dangers posed to astronauts traveling through space and invokes images from movies to introduce the concept of space weather, the disturbances imparted in the
interplanetary medium by flares and other outbursts from the Sun.
So it's reasonable to say that the
interplanetary medium delivered large amounts of organic materials onto Earth.
