Connection of the solar wind with the interstellar medium through numerical modeling

AIP Conference Proceedings, 2013
In this paper we investigate the interaction between the solar wind (SW) and the local interstellar medium (LISM) using spacecraft data and numerical simulations. In particular, we will focus on neutral atom results from NASA’s Interstellar Boundary EXplorer (IBEX) mission, and compare these with implementations of our neutral atom models that look at ...

How catching the interstellar wind in the inner solar system led the way on a road to interdisciplinary research between heliophysics and astrophysics

Frontiers in Astronomy and Space Sciences, 2023
Combined in situ observations of the interstellar wind through the solar system and of its pickup ions (PUIs), implanted after ionization in the solar wind, explain, in comparison with interstellar absorption lines of nearby stars, that the Sun is in an ...

STELLA—Potential European contributions to a NASA-led interstellar probe

Frontiers in Astronomy and Space Sciences, 2022
The discovery of a myriad of exoplanets in the past decades has revolutionized the understanding of our place in the Universe. How different are exoplants and do some of them harbor life, just like Earth? To do so, their parent stars must drive a stellar

Propagation of large-scale solar wind events in the outer heliosphere from a numerical MHD simulation

Earth and Planetary Physics, 2021
Voyager 1 occasionally detected sudden jumps of the local interstellar magnetic field strength since its heliopause crossing in August 2012. These events were believed to be associated with outward propagating solar wind shocks originating in the inner ...

Voyager Observations of Electron Densities in the Very Local Interstellar Medium

The Astrophysical Journal, 2023
The two Voyager spacecraft have now been immersed in the very local interstellar medium for several years. Both spacecraft carry a plasma wave instrument capable of detecting plasma waves that yield electron density through the determination of the ...

A future interstellar probe on the dynamic heliosphere and its interaction with the very local interstellar medium: In-situ particle and fields measurements and remotely sensed ENAs

Frontiers in Astronomy and Space Sciences, 2023
The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

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

The Astrophysical Journal, 2023
Angular scattering (AS) in charge exchange and elastic collisions between interstellar ions and neutral (ISN) atoms has been assumed to be negligible in previous studies.

The Direction of the Flow of Interstellar Neutral H Based on Photometric Observations from SOHO/SWAN

The Astrophysical Journal, 2023
Interstellar neutral hydrogen flows into the heliosphere as a mixture of the primary and secondary populations from two somewhat different directions due to splitting occurring in the magnetized outer heliosheath.

Determining the Ionization Rates of Interstellar Neutral Species Using Direct-sampling Observations of Their Direct and Indirect Beams

The Astrophysical Journal Supplement Series, 2023
A good understanding of the ionization rates of neutral species in the heliosphere is important for studies of the heliosphere and planetary atmospheres.

Relative In-flight Response of IBEX-Lo to Interstellar Neutral Helium Atoms

The Astrophysical Journal Supplement Series, 2023
The IBEX-Lo instrument on the Interstellar Boundary Explorer (IBEX) mission measures interstellar neutral (ISN) helium atoms. The detection of helium atoms is made through negative hydrogen (H ^− ) ions sputtered by helium atoms from the IBEX-Lo’s ...
