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 ...

New Insights From Long-Term Measurements of Inner Belt Protons (10s of MeV) by SAMPEX, POES, Van Allen Probes, and Simulation Results. [PDF]
J Geophys Res Space Phys, 2020 Abstract The Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX) mission provided long‐term measurements of 10s of megaelectron volt (MeV) inner belt (L < 2) protons (1992–2009) as did the Polar‐orbiting Operational Environmental Satellite‐18 (POES‐18, 2005 to present).

Using Lyman-α to probe the interior and edges of the heliosphere
Frontiers in Astronomy and Space Sciences, 2022 Understanding the role of neutral atoms in the heliospheric interface (between the bow shock and heliopause) is critical to identifying dynamics within our local bubble.

On the Vitality, or Lack Thereof, in Heliospheric and Coronal Physics
Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023 Abstract Heliospheric physics is the study of all phenomena in the solar wind, which carves out the heliosphere from the local interstellar medium. Coronal physics is the study of all phenomena in the solar corona, which creates the supersonic wind and all disturbances and variations contained therein.

Ensemble Forecasts of Solar Wind Connectivity to 1 Rs Using ADAPT‐WSA
Space Weather, Volume 21, Issue 10, October 2023., 2023 Abstract The solar wind which arrives at any location in the solar system is, in principle, relatable to the outflow of solar plasma from a single source location. This source location, itself usually being part of a larger coronal hole, is traceable to 1 RS along the Sun's magnetic field, in which the entire path from 1 RS to a location in the ...

Perspectives of Earth and Space Scientists, Volume 3, Issue 1, December 2022., 2022 Abstract The last two decades of cosmic ray research have been eventful, to say the least. The Voyager spacecraft explored the outer‐most regions of the heliosphere and eventually left our local astrosphere to explore the galaxy. At the same time, the Parker Solar Probe spacecraft, amongst many other exciting recent missions, is exploring the inner ...

Meteoritics &Planetary Science, Volume 57, Issue 3, Page 603-634, March 2022., 2022 Abstract We report the concentrations and isotope ratios of light noble gases (He, Ne, Ar) in 10 small basalt fragments derived from lunar regolith soils at the Apollo 12 landing site. We use cosmic ray exposure (CRE) and shielding condition histories to consider their geological context.

1I/‘Oumuamua as an N2 Ice Fragment of an exo‐Pluto Surface: I. Size and Compositional Constraints
Journal of Geophysical Research: Planets, Volume 126, Issue 5, May 2021., 2021 Abstract The origin of the interstellar object 1I/‘Oumuamua has defied explanation. We perform calculations of the non‐gravitational acceleration that would be experienced by bodies composed of a range of different ices and demonstrate that a body composed of N2 ice would satisfy the available constraints on the non‐gravitational acceleration, size ...
