Evolution of the optical spectrum of SN 1987a in the Large Magellanic Cloud

Ashoka, B. N; Anupama, G. C; Prabhu, T. P; Giridhar, S; Ghosh, K. K; Jain, S. K; Pati, A. K; Kameswara Rao, N (Indian Academy of Sciences, 1987-06)

The evolution of the spectrum of SN 1987a is traced from 1987 February 26 to March 31. Based on the low-resolution spectroscopic data the authors identify the lines of H, He I, Na I, Fe II, Sc II, Ca II which are known to ...
Neutrino emission from supernovae in the presence of magnetic fields

Sivaram, C (Kluwer Academic Publishers, 1989)

Neutrino burst observations from SN1987A indicate that the density and the temperature of the source and the propagation of the neutrinos in the medium are markedly different from those of solar and terrestrial conditions. ...
Supernova SN 1987A - Rotation rate of the central pulsar

Bhatt, H. C; Datta, B (Royal Astronomical Society, 1989-04)

Using available observational data on supernova SN 1987A, firm quantitative lower limits on the rotation period of the central pulsar (assuming the pulsar luminosity to power the supernova light curve) are derived. It is ...
