Three-dimensional modeling of the asymmetric blast wave from the 2006 outburst of RS Ophiuchi: Early X-ray emission (2008)

Orlando, S., Drake, J. J., Laming, J. M.

Chandra/HETG observations of the recurrent nova RS Ophiuchi at day 13.9 of its 2006 outburst reveal a spectrum covering a large range in plasma temperature and characterized by asymmetric and...

Non-Maxwellian Proton Velocity Distributions in Nonradiative Shocks (2008)

Raymond, J. C., Isenberg, Philip A., Laming, J. M.

The Balmer line profiles of nonradiative supernova remnant shocks provide the means to measure the post-shock proton velocity distribution. While most analyses assume a Maxwellian velocity...

A Deep Chandra Observation of Kepler's Supernova Remnant: A Type Ia Event with Circumstellar Interaction (2007)

Reynolds, S. P., Borkowski, K. J., Hwang, U., Hughes, J. P., Badenes, C., Laming, J. M., ...

We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence of O-rich ejecta,...

Collisional ionization equilibrium for optically thin plasmas. I. Updated recombination rate coefficients for bare through sodium-like ions (2006)

The Solar Helium Abundance in the Outer Corona Determined from Observations with SUMER/SOHO (2000)

Laming, J. M., Feldman, U.

At altitudes of about 1.05 solar radii or more, the corona above quiet solar regions becomes essentially isothermal. This obviates many of the difficulties associated with the inverse problem of...

Neutrino Induced Electrostatic Waves in Degenerate Electron Plasmas (1999)

Laming, J. M.

The plasma theory of electrostatic waves generated collisionlessly when neutrinos pass through degenerate electrons is developed. It is consistent with the results of calculations using quantum...
