Late Spectral Evolution of SN 1987A: I. Temperature and Ionization
The temperature and ionization of SN 1987A is modeled between 200 and 2000 days in its nebular phase, using a time-dependent model. We include all important elements, as well as the primary composition zones in the supernova. The energy input is provided by radioactive decay of 56Co, 57Co, and 44Ti. The thermalization of the resulting gamma-rays and positrons is calculated by solving the Spence...
متن کاملPolarization of SN 1987A Revisited
The conventional picture for the origin of the polarization of a supernova is based on a model of Thomson or resonance scattering of photons traveling through an aspherical supernova atmosphere. Positive detection of intrinsic polarization in SN 1987A is then interpretated as evidence of an asymmetrical supernova atmosphere. We show here a di erent view based on the scattering of the supernova ...
متن کاملCCD photometry of young MC clusters I : NGC 2172 ?
We present a new CCD photometry for the young LMC cluster NGC 2172, giving B, V, I magnitudes for more than 600 stars within 70 ′′ from the cluster center, down to approximatelyV = 21 mag. After correction for completeness and field stars contamination, we discuss the cluster HR diagram and the MS luminosity function in the light of current evolutionary theories and in connection with the probl...
متن کاملX-ray Evolution of SN 1987A
The X-ray observations of SN 1987A over the previous 20 years have seen the emergence of soft X-rays from the interaction of the explosion shock wave with the ambient medium. This shock wave is now interacting strongly with the inner ring and might have passed already the highest density regions. The emission can be described by thermal models with temperatures of ∼0.28 keV and ∼2.8+0.7 −1.0 ke...
متن کاملUbv Ri Photometry of Sn 1993j in M81: Days 3 to 365
We present optical photometry of SN 1993J in M81 over the period 1993 March 30 to 1994 March 28, exactly one year after its discovery, recalibrating early data we had published in a previous paper and describing new data which cover the latter six months. At late times, the supernova's luminosity declined exponentially in BV RI, at a rate much faster than that of most Type II SNe. The rate of d...
