Propagation of Solar Energetic Particles in the Outer Heliosphere: Interplay between Scattering and Adiabatic Focusing
H.-Q. He; W. Wan
<jats:title>Abstract</jats:title> <jats:p>The turbulence and spatial nonuniformity of the guide magnetic field cause two competitive effects, namely, the scattering effect and the adiabatic focusing effect, respectively. In this work, we numerically solve the five-dimensional Fokker–Planck transport equation to investigate the radial evolutions of these important effects undergone by the solar energetic particles (SEPs) propagating through interplanetary space. We analyze the interplay process between the scattering and adiabatic focusing effects in the context of three-dimensional propagation, with special attention to the scenario of the outer heliosphere, in which some peculiar SEP phenomena are found and explained. We also discuss the radial dependence of the SEP peak intensities from the inner through the outer heliosphere, and conclude that it cannot be simply described by a single functional form such as <jats:italic>R</jats:italic> <jats:sup>−<jats:italic>α</jats:italic> </jats:sup> (<jats:italic>R</jats:italic> is radial distance), which is often used.</jats:p>

First Detection of Submillimeter-wave [13C i] 3P1–3P0 Emission in a Gaseous Debris Disk of 49 Ceti with ALMA
Aya E. Higuchi; Yoko Oya; Satoshi Yamamoto
<jats:title>Abstract</jats:title> <jats:p>We have detected the submillimeter-wave fine-structure transition (<jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>1</jats:sub>–<jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>0</jats:sub>) of <jats:sup>13</jats:sup>C, [<jats:sup>13</jats:sup>C <jats:sc>i</jats:sc>], in the gaseous debris disk of 49 Ceti with the Atacama Large Millimeter/submillimeter Array (ALMA). Recently, the [C <jats:sc>i</jats:sc>] <jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>1</jats:sub>–<jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>0</jats:sub> emission has been spatially resolved in this source with ALMA. In this data set, the <jats:italic>F</jats:italic> = 3/2–1/2 hyperfine component of [<jats:sup>13</jats:sup>C <jats:sc>i</jats:sc>], which is blueshifted by 2.2 km s<jats:sup>−1</jats:sup> from the normal species line, [C <jats:sc>i</jats:sc>], has been identified in the outer part of the 49 Ceti disk, thanks to the narrow velocity widths of the gas components. The [C <jats:sc>i</jats:sc>]/[<jats:sup>13</jats:sup>C <jats:sc>i</jats:sc>] line intensity ratio is found to be 12 ± 3, which is significantly lower than the <jats:sup>12</jats:sup>C/<jats:sup>13</jats:sup>C abundance ratio of 77 in the interstellar medium. This result clearly reveals that the [C <jats:sc>i</jats:sc>] emission is optically thick in 49 Ceti at least partly, as speculated by the previous work. As far as we know, this is the first detection of [<jats:sup>13</jats:sup>C <jats:sc>i</jats:sc>] <jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>1</jats:sub>–<jats:sup>3</jats:sup> <jats:italic>P</jats:italic> <jats:sub>0</jats:sub> emission at 492 GHz not only in debris disks but also in the interstellar medium.</jats:p>
