AB - We revisit the evidence for the contribution of the long-lived radioactive nuclides 44Ti, 55Fe, 56Co, 57Co, and 60Co to the UVOIR light curve of SN 1987A. Consideration of the kinetic energy of these electrons is essential in lowering our best fit nickel isotope production ratio to [57Ni/56Ni] = 2.5 ± 1.1, which is still somewhat high but is in agreement with gamma-ray observations and model predictions. The light curve of SN 1987A revisited: Constraining production masses of radioactive nuclides, Constraining production masses of radioactive nuclides, nuclear reactions, nucleosynthesis, abundances. Together they form a unique fingerprint.

In this model, the energy liberated from the pulsar is assumed to be confined in the cavity and the cavity expands by pushing the supernova ejecta.

Our best fit 44Ti mass is M(44Ti) = (0.55 ± 0.17) × 10-4 M ⊙, which is in disagreement with the much higher (3.1 ± 0.8) × 10-4 M ⊙ recently derived from INTEGRAL observations. The optical display of the supernova will commence when the blast arrives at the photosphere, an event called shock breakout.

T1 - The light curve of SN 1987A revisited, T2 - Constraining production masses of radioactive nuclides. The associated uncertainties far exceed the best fit values for 55Co and 60Co and, as a result, we only give upper limits on the production masses of M(55Co) < 7.2 × 10-3 M ⊙ and M(60Co) < 1.7 × 10-4 M ⊙.

Within 107 minutes of the Kamiokande 1MB neutrino event the region of the supernova was being observed by Albert Jones, although it was not until 0.8 days after the event that the supernova was officially discovered by Shelton. By continuing you agree to the use of cookies. During this time the supernova steadily brightened in V, although theory predicts that it was rapidly fading bolometrically and cooling, after the intense heating that occurred when the shock wave reached the stellar surface about 3 hours after core collapse. Full text views reflects the number of PDF downloads, PDFs sent to Google Drive, Dropbox and Kindle and HTML full text views. Considering the five most relevant decay chains starting at 44Ti, 55Co, 56Ni, 57Ni, and 60Co, we perform a least squares fit to the constructed composite bolometric light curve.

Furthermore, the distance to the LMC is known in absolute units with a precision of about ± 15% (m-M = 18.45, Feast 1988) which combined with the above data and subseguent photometric observations permits detailed comparison with theory.

We revisit the evidence for the contribution of the long-lived radioactive nuclides 44 Ti, 55 Fe, 56 Co, 57 Co, and 60 Co to the UVOIR light curve of SN 1987A.
