SPH simulations of star/planet formation triggered by cloud-cloud collisions
Spyridon Kitsionas, Anthony P. Whitworth, Ralf S. Klessen
We present results of hydrodynamic simulations of star formation triggered by cloud-cloud collisions. During the early stages of star formation, low-mass objects form by gravitatio…
Freshly Formed Dust in the Cassiopeia A Supernova Remnant as Revealed by the Spitzer Space Telescope
J. Rho, T. Kozasa, W. T. Reach +6
We performed Spitzer Infrared Spectrograph mapping observations covering nearly the entire extent of the Cassiopeia A supernova remnant (SNR), producing mid-infrared (5.5-35 micron…
Ion pick-up by finite amplitude parallel propagating Alfvén wave
X. Li, Q. M. Lu, B. Li
Two scenarios of possible ion heating due to finite amplitude parallel propagating Alfvén waves in the solar atmosphere are investigated using a 1D test particle approach. 1. An fi…
O VI and H_2 Lines in Sunspots
Nicolas Labrosse, Huw Morgan, Shadia Rifai Habbal +1
Sunspots are locations on the Sun where unique atmospheric conditions prevail. In particular, the very low temperatures found above sunspots allow the emission of H_2 lines. In thi…
Spectral Diagnostics of Active Prominences
Nicolas Labrosse, Pierre Gouttebroze, Jean-Claude Vial
Active prominences exhibit plasma motions, resulting in difficulties with the interpretation of spectroscopic observations. These solar features being strongly influenced by the ra…
Spitzer IRAC Images and Sample Spectra of Cassiopeia A's Explosion
J. A. Ennis, L. Rudnick, W. T. Reach +5
We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most se…
