Infrared emission from novae
A. Evans, R. D. Gehrz
We review infrared observations of classical and recurrent novae, at wavelengths >3microns, including both broad-band and spectroscopic observations. In recent years infrared spect…
Elemental Abundances in the Ejecta of Old Classical Novae from Late-Epoch Spitzer Spectra
L. Andrew Helton, Robert D. Gehrz, Charles E. Woodward +7
We present Spitzer Space Telescope mid-infrared IRS spectra, supplemented by ground-based optical observations, of the classical novae V1974 Cyg, V382 Vel, and V1494 Aql more than…
Infrared observations of the recurrent nova T Pyxidis: ancient dust basks in the warm glow of the 2011 outburst
A. Evans, R. D. Gehrz, L. A. Helton +15
We present Spitzer Space Telescope and Herschel Space Observatory infrared observations of the recurrent nova T Pyx during its 2011 eruption, complemented by ground-base optical-in…
Properties and Spatial Distribution of Dust Emission in the Crab Nebula
Tea Temim, George Sonneborn, Eli Dwek +4
Recent infrared (IR) observations of freshly-formed dust in supernova remnants (SNRs) have yielded significantly lower dust masses than predicted by theoretical models and measured…
Early Science with SOFIA, the Stratospheric Observatory for Infrared Astronomy
E. T. Young, E. E. Becklin, P. M. Marcum +38
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7-m telescope, flying at altitudes…
Presolar Grains from Novae: Evidence from Neon and Helium Isotopes in Comet Dust Collections
Robert O. Pepin, Russell L. Palma, Robert D. Gehrz +1
Presolar grains in meteorites and interplanetary dust particles (IDPs) carry non-solar isotopic signatures pointing to origins in supernovae, giant stars, and possibly other stella…
