A binary merger model for the formation of the supernova 1987A triple-ring nebula.
MORRIS T. and PODSIADLOWSKI Ph.
Abstract (from CDS):
We present a parameter study from which we determine a mass-loss rate in the blue supergiant wind in the range 1.5-3 x10–7M☉/yr in agreement with previous estimates. The morphology of the best model is consistent with the well-known Hubble Space Telescope image at better than 5 per cent and is also in broad agreement with light-echo observations. The circumstellar environment on larger scales (up to 3pc) is also investigated. We conclude with a brief discussion of the bipolar nebulae surrounding the Galactic stars, Sheridan 25, HD 168625 and η Carinae.
