The stellar content of the WR galaxy NGC5253 from ISO/SWS spectroscopy (2007)
Paul A. Crowther, Sara C. Beck, Allan J. Willis, Peter S. Conti, Patrick W. Morris, Ralph S. Sutherland
1. Why mid-IR spectroscopy of WR galaxies? Wolf-Rayet (WR) galaxies are a subset of blue emission-line galaxies whose spectra show the signature of large numbers of WR stars with ages in the range
Morris, Patrick W., Stolovy, Susan, Wachter, Stefanie, Noriega-Crespo, Alberto, Pannuti, Thomas G., Hoard, D. W.
We have discovered an axially symmetric, well-defined shell of material in the constellation of Cepheus, based on imaging acquired as part of the Galactic First Look Survey with the Spitzer Space...
Quantitative analysis of WC stars: Constraints on neon abundances from ISO/SWS spectroscopy (2000)
Dessart, Luc, Crowther, Paul A., Hillier, D. John, Willis, Allan J., Morris, Patrick W., Van Der Hucht, Karel A.
Neon abundances are derived in four Galactic WC stars -- gamma Vel (WR11, WC8+O7.5III), HD156385 (WR90, WC7), HD192103 (WR135, WC8), and WR146 (WC5+O8) - using mid-infrared fine structure lines...
