Detection of CO ice in the planetary nebula NGC 6302
Charmi Bhatt, Simon W. Cao, Jan Cami +20
Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…
The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation
Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34
NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
Physical Properties of Fullerene-containing Galactic Planetary Nebulae
Masaaki Otsuka, F. Kemper, J. Cami +2
We searched the Spitzer Space Telescope data archive for Galactic planetary nebulae (PNe), that show the characteristic 17.4 and um features due to C60, also known as buckminsterfu…
Silicate features in Galactic and extragalactic post-AGB discs
C. Gielen, J. Bouwman, H. Van Winckel +7
Aims. In this paper we study the Spitzer and TIMMI2 infrared spectra of post-AGB disc sources, both in the Galaxy and the LMC. Using the observed infrared spectra we determine the…
The Spitzer discovery of a galaxy with infrared emission solely due to AGN activity
S. Hony, F. Kemper, Paul M. Woods +14
We present a galaxy (SAGE1CJ053634.78-722658.5) at a redshift of 0.14 of which the IR is entirely dominated by emission associated with the AGN. We present the 5-37 um Spitzer/IRS…
The 9.7 and 18 um silicate absorption profiles towards diffuse and molecular cloud lines-of-sight
J. M. van Breemen, M. Min, J. E. Chiar +8
Studying the composition of dust in the interstellar medium (ISM) is crucial in understanding the cycle of dust in our galaxy. The mid-infrared spectral signature of amorphous sili…
