The compact object and innermost ejecta of SN 1987A
J. Larsson, C. Fransson, P. J. Kavanagh +12
The first JWST observations of SN 1987A provided clear evidence that a compact object is ionizing the innermost ejecta. Here we analyze a second epoch of JWST NIRSpec and MIRI/MRS…
Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
G. C. Sloan, K. E. Kraemer, B. Aringer +9
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significan…
Evidence for late-time dust formation in the ejecta of supernova SN~1995N from emission-line asymmetries
R. Wesson, A. M. Bevan, M. J. Barlow +4
We present a study of the dust associated with the core-collapse supernova SN~1995N. Infrared emission detected 14--15 years after the explosion was previously attributed to therma…
Properties of shocked dust grains in supernova remnants
F. D. Priestley, H. Chawner, M. J. Barlow +3
Shockwaves driven by supernovae both destroy dust and reprocess the surviving grains, greatly affecting the resulting dust properties of the interstellar medium (ISM). While these…
Quantifying the dust in SN 2012aw and iPTF14hls with ORBYTS
Maria Niculescu-Duvaz, M. J. Barlow, W. Dunn +32
Core-collapse supernovae (CCSNe) are potentially capable of producing large quantities of dust, with strong evidence that ejecta dust masses can grow significantly over extended pe…
The Mass-Loss Return from Evolved Stars to the Large Magellanic Cloud II: Dust Properties for Oxygen-Rich Asymptotic Giant Branch Stars
Benjamin A. Sargent, S. Srinivasan, M. Meixner +11
We model multi-wavelength broadband UBVIJHKs and Spitzer IRAC and MIPS photometry and IRS spectra from the SAGE and SAGE-Spec observing programs of two oxygen-rich asymptotic giant…
OH/IR stars and their superwinds as observed by the Herschel Space Observatory
K. Justtanont, D. Teyssier, M. J. Barlow +4
Aim : In order to study the history of mass loss in extreme OH/IR stars, we observed a number of these objects using CO as a tracer of the density and temperature structure of thei…
The mass-loss return from evolved stars to the Large Magellanic Cloud III. Dust properties for carbon-rich asymptotic giant branch stars
Sundar Srinivasan, B. A. Sargent, M. Matsuura +9
We present a 2Dust model for the dust shell around a LMC long-period variable (LPV) previously studied as part of the OGLE survey. OGLE LMC LPV 28579 (SAGE J051306.40-690946.3) is…
Dust in the bright supernova remnant N49 in the LMC
M. Otsuka, J. Th. van Loon, K. S. Long +14
We investigate the dust associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC) as observed with the Herschel Space Observatory. N49 is unusually bright…
