Global Heliospheric Termination Shock Strength in the Solar-Interstellar Interaction
E. J. Zirnstein, R. Kumar, B. L. Shrestha +4
A heliospheric termination shock (HTS) surrounds our solar system at approximately 100 astronomical units from the Sun, where the expanding solar wind (SW) is compressed and heated…
Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models
P. Swaczyna, M. Bzowski, K. Dialynas +12
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge exchange collisions in the outer he…
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…
Slowdown and Heating of Interstellar Neutral Helium by Elastic Collisions Beyond the Heliopause
P. Swaczyna, F. Rahmanifard, E. J. Zirnstein +2
Direct sampling of interstellar neutral (ISN) atoms close to the Sun enables studies of the very local interstellar medium (VLISM) around the heliosphere. The primary population of…
Interstellar neutral helium in the heliosphere from IBEX observations. VI. The He density and the ionization state in the Very Local Interstellar Matter
M. Bzowski, A. Czechowski, P. C. Frisch +14
Interstellar neutral gas atoms penetrate the heliopause and reach 1~au, where they are detected by IBEX. The flow of neutral interstellar helium through the perturbed interstellar…
Interstellar neutral helium in the heliosphere from IBEX observations. V. Observations in IBEX-Lo ESA steps 1, 2, & 3
Paweł Swaczyna, Maciej Bzowski, Marzena A. Kubiak +9
Direct-sampling observations of interstellar neutral (ISN) He by Interstellar Boundary Explorer (IBEX) provide valuable insight into the physical state of and processes operating i…
Modeling Emission of Heavy Energetic Neutral Atoms from the Heliosphere
Pawel Swaczyna, Maciej Bzowski
Observations of energetic neutral atoms (ENAs) are a fruitful tool for remote diagnosis of the plasma in the heliosphere and its vicinity. So far, instruments detecting ENAs from t…
Helium Energetic Neutral Atoms from the Heliosphere: Perspectives for Future Observations
Paweł Swaczyna, Stan Grzedzielski, Maciej Bzowski
Observations of energetic neutral atoms (ENAs) allow for remote sensing of plasma properties in distant regions of the heliosphere. So far, most of the observations have concerned…
The energy-dependent position of the IBEX ribbon due to the solar wind structure
Paweł Swaczyna, Maciej Bzowski, Justyna M. Sokół
Observations of energetic neutral atoms (ENAs) allow for remote studies of the plasma condition in the heliosphere and the neighboring local interstellar medium. The first IBEX res…
Distance to the IBEX Ribbon Source Inferred from Parallax
P. Swaczyna, M. Bzowski, E. R. Christian +3
Maps of Energetic Neutral Atom (ENA) fluxes obtained from Interstellar Boundary Explorer (IBEX) observations revealed a bright structure extending over the sky, subsequently dubbed…

With the velocity vector and temperature of the pristine interstellar neutral (ISN) He recently obtained with high precision from a coordinated analysis summarized by McComas et al…
Reconstruction of Helio-latitudinal Structure of the Solar Wind Proton Speed and Density
Justyna M. Sokół, Paweł Swaczyna, Maciej Bzowski +1
The modeling of the heliosphere requires continuous three-dimensional solar wind data. The in-situ out-of-ecliptic measurements are very rare, so that other methods of solar wind d…
