HCO and the Effect of Mixing in SN 1987A
H. M. Davies, M. Matsuura, H. L. Gomez +8
We present high angular resolution observations of the HCO emission in the central ejecta of the supernova remnant SN 1987A using the Atacama Large Millimeter Array (ALMA). We…
Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…
The evolution of the mid-infrared spectrum of SN 1987A observed with the JWST/MIRI-MRS
P. J. Kavanagh, M. J. Barlow, C. Fransson +19
Supernova (SN) 1987A provides a unique laboratory for investigating many aspects of SN physics and evolution. An observation at Day 12927 (35.4 yr) since the explosion with the Mid…
Dust destruction by the supernova remnant forward shock in a turbulent interstellar medium
Tassilo Scheffler, Nina S. Sartorio, Florian Kirchschlager +3
Context. While supernova remnants (SNRs) are observed to produce up to 1 M of dust, the amount of dust destroyed by the forward shock (FS) is poorly constrained, raising th…
WEAVE imaging spectroscopy of NGC 6720: an iron bar in the Ring
R. Wesson, J. E. Drew, M. J. Barlow +23
We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE, a new instrument m…
The Supernova 1987A system and its recent evolution - a review
Michael J. Barlow
Supernova 1987A was the closest supernova event to be observed in nearly 400 years. The outflowing ejecta from the explosion continues to interact with extended circumstellar mater…
