Energy release from radioactive decays contributes significantly to supernova light curves. Previous works, which considered the energy deposited by γ-rays and positrons produced by 56 Ni, 56 Co, 57 Ni, 57 Co, 44 Ti and 44 Sc, have been quite successful in explaining the light curves of both core collapse and thermonuclear supernovae. We point out that Auger and internal conversion electrons, together with the associated X-ray cascade, constitute an additional heat source. When a supernova is…

Seitenzahl et al. have predicted that roughly three years after its explosion, the light we receive from a Type Ia supernova (SN Ia) will come mostly from reprocessing of electrons and X-rays emitted

Prospects of direct detection of 48V gamma-rays from thermonuclear supernovae

Detection of gamma-rays emitted by radioactive isotopes synthesized in stellar explosions can give important insights into the processes that power transients such as supernovae, as well as

Constraints on the density distribution of type Ia supernovae ejecta inferred from late-time light-curve flattening

The finite time, τdep, over which positrons from β+ decays of 56Co deposit energy in type Ia supernovae ejecta lead, in case the positrons are trapped, to a slower decay of the bolometric

The Remnant of Supernova 1987A

Although it has faded by a factor of ∼107, SN 1987A is still bright enough to be observed in almost every band of the electromagnetic spectrum. Today, the bolometric luminosity of the debris is

The late-time light curve of the type Ia supernova SN 2011fe

We present late-time optical R-band imaging data from the Palomar Transient Factory (PTF) for the nearby Type Ia supernova SN 2011fe. The stacked PTF light curve provides densely sampled coverage

Late-time Flattening of Type Ia Supernova Light Curves: Constraints from SN 2014J in M82

The very nearby Type Ia supernova 2014J in M82 offers a rare opportunity to study the physics of thermonuclear supernovae at extremely late phases (≳800 days). Using the Hubble Space Telescope, we


In most astrophysical situations, the radioactive decay of to occurs via electron capture with a fixed half-life of 6.1 days. However, this decay rate is significantly slowed when the nuclei are


The Type Ia supernova SN 2011fe is one of the closest supernovae of the past decades. Due to its proximity and low dust extinction, this object provides a very rare opportunity to study the extremely

The light curve of SN 1987A revisited: constraining production masses of radioactive nuclides

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. We show that the V-band luminosity



Late Light Curves of Type Ia Supernovae

We extend earlier efforts to determine whether the late (t ≥ 60 days) light curves of Type Ia SNe are better explained by the escape of positrons from the ejecta or by the complete deposition of

Positron Escape from Type Ia Supernovae

We generate bolometric light curves for a variety of Type Ia supernova models at late times, simulating gamma-ray and positron transport for various assumptions about the magnetic field and

Gamma-Ray Transfer and Energy Deposition in Supernovae

Solutions to the energy-independent (gray) radiative transfer equations are compared to results of Monte Carlo simulations of the Ni-56 and Co-56 decay gamma-ray energy deposition in supernovae. The

Hard emission at late times from SN 1987A

A model for the explosion that has been successful in predicting and explaining the evolution of SN 1987A during its first one and one-half years is used to calculate the future photometric evolution

Bolometric Light Curves of Supernovae and Postexplosion Magnetic Fields

The various effects leading to diversity in the bolometric light curves of supernovae are examined; nucleosynthesis, kinematic differences, ejected mass, degree of mixing, and configuration and

Gamma rays, X-rays, and optical light from the cobalt and the neutron star in SN 1987A

Recent developments in modeling the X-ray and gamma-ray emission from SN 1987A are discussed by taking into account both the decaying cobalt and the buried neutron star. The light curve and the

Positrons from supernovae

Positrons are produced in the ejecta of supernovae by the decay of nucleosynthetic Co-56, Ti-44, and Al-26. We calculate the probability that these positrons can survive without annihilating in the

Late Spectral Evolution of SN 1987A. I. Temperature and Ionization

The temperature and ionization of SN 1987A are modeled time-dependently in its nebular phase between 200 and 2000 days. We include all important elements, as well as the primary composition zones in

The Freeze-out Phase of SN 1987A: Implications for the Light Curve

After ∼800 days, time-dependent effects due to long recombination and cooling times lead to a frozen-in structure of the ejecta of SN 1987A. The result is a higher bolometric luminosity, compared to

SN 1987A - Out on the tail

The expected light curve of Supernova 1987A is calculated for the next 10 yr based solely upon energy input from radioactive decay of Co-56 and Co-57. During the third year, energy input from Co-57
