Local Interstellar Flow Parameters from the First Intersection of IMAP-Lo's Parameter Tubes

Nathan A. Schwadron, Mitchell M. Shen, Fatemeh Rahmanifard +24

The Sun's motion through the interstellar medium creates a flow of interstellar neutral (ISN) atoms through the heliosphere. ISN He, due to its high universal abundance and relativ…

Fluctuating polytropic processes, turbulence, and heating

G. Livadiotis, D. J. McComas

This paper explores the thermodynamics of fluctuating polytropic processes and their connection to turbulence. It is shown that random fluctuations of polytropic processes produce…

Ionization Rate of Interstellar Neutral Helium from New Horizons/SWAP Observations

Małgorzata Antonik, Paweł Swaczyna, David J. McComas +2

Interstellar neutral (ISN) atoms enable studies of the physical conditions in the local interstellar medium surrounding the heliosphere. ISN helium, which is the most abundant spec…

The Effect of Angular Scattering Imposed by Charge Exchange and Elastic Collisions on Interstellar Neutral Hydrogen Atoms

F. Rahmanifard, P. Swaczyna, E. J. Zirnstein +7

Angular scattering in charge exchange and elastic collisions between interstellar ions and neutral (ISN) atoms has been assumed to be negligible in previous studies. Here, we inves…

Investigating the IBEX Ribbon Structure a Solar Cycle Apart

Maher A. Dayeh, Eric J. Zirnstein, Pawel Swaczyna +1

A Ribbon of enhanced energetic neutral atom (ENA) emissions was discovered by the Interstellar Boundary Explorer (IBEX) in 2009, redefining our understanding of the heliosphere bou…
