The Origins and Physical Properties of the Complex of Local Interstellar Clouds
Jonathan D. Slavin
The Complex of Local Interstellar Clouds (CLIC) is a relatively tight grouping of low density, warm, partially ionized clouds within about 15 pc of the Solar System. The Local Inte…
X-Atlas: An Online Archive of Chandra's Stellar High Energy Transmission Gratings Observations
Owen W. Westbrook, Nancy Remage Evans, Scott J. Wolk +6
The high-resolution X-ray spectroscopy made possible by the 1999 deployment of the Chandra X-ray Observatory has revolutionized our understanding of stellar X-ray emission. Many pu…
The Boundary Conditions of the Heliosphere: Photoionization Models Constrained by Interstellar and In Situ Data
Jonathan D. Slavin, Priscilla C. Frisch
The boundary conditions of the heliosphere are set by the ionization, density and composition of inflowing interstellar matter. Constraining the properties of the Local Interstella…
Evaporation and Thermal Balance of Tiny HI Clouds
Jonathan D. Slavin
We discuss the thermal evaporation of tiny HI clouds in the interstellar medium. Cold neutral clouds will take ~10^6 - 10^7 yr to evaporate if they are embedded in warm neutral gas…
Evidence for a High Carbon Abundance in the Local Interstellar Cloud
Jonathan D. Slavin, Priscilla C. Frisch
The nature of the Local Interstellar Cloud (LIC) is highly constrained by the combination of in situ heliospheric and line-of-sight data towards nearby stars. We present a new inte…
The Sun's Journey Through the Local Interstellar Medium: The PaleoLISM and Paleoheliosphere
P. C. Frisch, J. D. Slavin
Over the recent past, the galactic environment of the Sun has differed substantially from today. Sometime within the past ~130,000 years, and possibly as recent as ~56,000 years ag…
Short-term Variations in the Galactic Environment of the Sun
Priscilla C. Frisch, Jonathan D. Slavin
The galactic environment of the Sun varies over short timescales as the Sun and interstellar clouds travel through space. Small variations in the dynamics, ionization, density, and…
The Chemical Composition and Gas-to-Dust Mass Ratio of Nearby Interstellar Matter
Priscilla C. Frisch Jonathan D. Slavin
Recent results on nearby interstellar gas and interstellar byproducts within the solar system are used to select among the equilibrium radiative transfer models of the nearest inte…
The Ionization of Nearby Interstellar Gas
Jonathan D. Slavin, Priscilla C. Frisch
We present new calculations of the photoionization of interstellar matter within ~5 pc of the Sun (which we refer to as the Complex of Local Interstellar Clouds or CLIC) by directl…
Photoionization of Galactic Halo Gas by Old Supernova Remnants
Jonathan D. Slavin, Christopher F. McKee, David J. Hollenbach
We present new calculations on the contribution from cooling hot gas to the photoionization of warm ionized gas in the Galaxy. We show that hot gas in cooling supernova remnants (S…
Dust in the Local Interstellar Wind
P. C. Frisch, J. M. Dorschner, J. Geiss +13
The gas-to-dust mass ratios found for interstellar dust within the Solar System, versus values determined astronomically for the cloud around the Solar System, suggest that large a…
An Interstellar Conduction Front Within a Wolf-Rayet Ring Nebula Observed with the GHRS
Bram Boroson, Richard McCray, Christina Oelfke Clark +4
With the High Resolution Spectrograph aboard the Hubble Space Telescope we obtained high signal-to-noise (S/N > 200 - 600 per 17 km/s resolution element) spectra of narrow absorpti…
