Evidence for Spatially Distinct Galactic Dust Populations

The Astrophysical Journal
We present an implementation of a Bayesian mixture model using Hamiltonian Monte Carlo techniques to search for the spatial separation of Galactic dust populations. Utilizing intensity measurements from the Planck High Frequency Instrument, we apply this

Determination of interstellar pickup ion distributions in the solar wind with SOHO and Cluster

Annales Geophysicae
Over the last 10 years, the experimental basis for the study of the local interstellar medium has been substantially enhanced by the direct detection of interstellar pickup ions and of interstellar neutral helium within the heliosphere.

Deep Search for Phosphine in a Prestellar Core

The Astrophysical Journal Letters
Understanding in which chemical forms phosphorus exists in star- and planet-forming regions and how phosphorus is delivered to planets are of great interest from the viewpoint of the origin of life on Earth.

A Framework for Incorporating Binding Energy Distribution in Gas-ice Astrochemical Models

The Astrophysical Journal
One of the most serious limitations of current astrochemical models with the rate equation (RE) approach is that only a single type of binding site is considered in grain surface chemistry, although laboratory and quantum chemical studies have found that

Possible interaction of interstellar particles with the solar and terrestrial environment [PDF]

The possibility for detection of interstellar particles in the earth's environment is considered on the basis of the passage of the solar system through the interstellar medium.
