Supernova Remnants in the Sedov Expansion Phase: Thermal X-Ray Emission
Improved calculations of X-ray spectra for supernova remnants (SNRs) in the Sedov-Taylor phase are reported, which for the first time include reliable atomic data for Fe L-shell lines. This new set
Transition to the Radiative Phase in Supernova Remnants
The evolution of a supernova remnant through the transition from an adiabatic Sedov-Taylor blast wave to a radiative pressure-driven snowplow phase is studied using one- and two-dimensional
Systematic Spatial Variations of the Spectrum of Synchrotron X-rays from the Youngest Galactic Supernova Remnant G1.9+0.3
Our 50 ks Chandra observation of the small radio supernova remnant (SNR) G1.9+0.3 shows a complete shell structure with strong bilateral symmetry, about 100'' in diameter. The radio morphology is
Constraints on the physics of type ia supernovae from the x-ray spectrum of the tycho supernova remnant
We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion. Most models for Type Ia
RADIOACTIVE SCANDIUM IN THE YOUNGEST GALACTIC SUPERNOVA REMNANT G1.9+0.3
We report the discovery of thermal X-ray emission from the youngest Galactic supernova remnant G1.9+0.3, from a 237 ks Chandra observation. We detect strong K? lines of Si, S, Ar, Ca, and Fe. In
The radio expansion and brightening of the very young supernova remnant G1.9 + 0.3
Recent radio observations of the small Galactic supernova remnant G1.9 + 0.3 made at 4.86 GHz with the Very Large Array are presented, and compared with earlier observations at 1.49 GHz which have a
ROSAT/ASCA observations of the mixed-morphology supernova remnant W28
We present three sets of ROSAT Position Sensitive Proportional Counter and four sets of ASCA observations of the supernova remnant (SNR) W28. The overall shape of X-ray emission in W28 is elliptical,
RCW 86: A TYPE Ia SUPERNOVA IN A WIND-BLOWN BUBBLE
We report results from a multi-wavelength analysis of the Galactic supernova remnant RCW?86, the proposed remnant of the supernova of 185 A.D. We show new infrared observations from the Spitzer Space
A Massive Shell of Supernova-Formed Dust in SNR G54.1+0.3
While theoretical dust condensation models predict that most refractory elements produced in core-collapse supernovae (SNe) efficiently condense into dust, a large quantity of dust has so far only
Radiative magnetized thermal conduction fronts
The evolution of plane-parallel magnetized thermal conduction fronts in the interstellar medium (ISM) was studied. Separating the coronal ISM phase and interstellar clouds, these fronts have been
