Cometary Astropause of Mira Revealed in the Far-Infrared

, 2008
Evolved mass-losing stars such as Mira enrich the interstellar medium (ISM) significantly by their dust-rich molecular wind. When these stars move fast enough relative to the ISM, the interaction between the wind and ISM generates the structure known as ...

A Catalog of Pulsar X-Ray Filaments

The Astrophysical Journal
We present the first Chandra X-ray Observatory (CXO) catalog of “pulsar X-ray filaments,” or “misaligned outflows.” These are linear, synchrotron-radiating features powered by ultrarelativistic electrons and positrons that escape from bow shock pulsars ...

The Outer Shock of the Oxygen-Rich Supernova Remnant G292.0+1.8: Evidence for the Interaction with the Stellar Winds from its Massive Progenitor

, 2010
We study the outer-shock structure of the oxygen-rich supernova remnant G292.0+1.8, using a deep observation with the Chandra X-ray Observatory. We measure radial variations of the electron temperature and emission measure that we identify as the outer ...

An MHD study of the interaction between the solar wind and the interstellar medium [PDF]

The overall objective of this research program is to obtain a better understanding of the interaction between the solar wind and the interstellar medium through the use of numerical solutions of the time-dependent magnetohydrodynamic (MHD) equations. The

Positrons from pulsar winds

, 2010
Pulsars, or more generally rotation powered neutron stars, are excellent factories of antimatter in the Galaxy, in the form of pairs of electrons and positrons.

Signal Processing for the Measurement of the Deuterium/Hydrogen Ratio in the Local Interstellar Medium

Entropy, 2014
We report on a comprehensive signal processing procedure for very low signal levels for the measurement of neutral deuterium in the local interstellar medium from a spacecraft in Earth orbit.

Effects of interstellar particles upon the interplanetary magnetic field [PDF]

The flow of interstellar neutral particles into the interplanetary medium and their subsequent ionization in the presence of the electromagnetic field of the solar wind can cause a loss of field angular momentum by the solar wind. One effect of this loss

Anomalous Neutral Hydrogen Column Densities in Local Interstellar Medium Clouds

The Astrophysical Journal
Analysis of high-resolution spectra of the hydrogen and deuterium Ly α lines provides measurements of interstellar neutral hydrogen column densities N (H i ) to 113 stars within 50 pc of the Sun. Plots of N (H i ) versus distance through the LIC, G, Mic,

Shock evolution in non-radiative supernova remnants

, 2016
We present a new analytical approach to derive approximate solutions describing the shock evolution in non-radiative supernova remnants (SNRs). We focus on the study of the forward shock and contact discontinuity while application to the reverse shock is

Weakly Compressible Magnetohydrodynamic Turbulence in the Solar Wind and the Interstellar Medium

The Astrophysical Journal, 1998
A new four-field system of equations is derived from the compressible magnetohydrodynamic (MHD) equations for low Mach number turbulence in the solar wind and the interstellar medium, permeated by a spatially varying magnetic field. The plasma beta is assumed to be of order unity or less.
