The mass of synthesised radioactive material is an important power source for all supernova (SN) types. Anderson 2019 recently compiled literature values and obtained $^{56}$Ni distributions for different core-collapse supernovae (CC-SNe), showing that the $^{56}$Ni distribution of stripped envelope CC-SNe (SE-SNe: types IIb, Ib, and Ic) is highly incompatible with that of hydrogen rich type II SNe (SNe-II). This motivates questions on differences in progenitors, explosion mechanisms, and $^{56… 
The γ-ray deposition histories of core-collapse supernovae
The γ-ray deposition history in an expanding supernova (SN) ejecta has been mostly used to constrain models for Type Ia SN. Here we expand this methodology to core-collapse SNe, including stripped
Comparing Moment-based and Monte Carlo Methods of Radiation Transport Modeling for Type II-Plateau Supernova Light Curves
Time-dependent electromagnetic signatures from core-collapse supernovae are the result of detailed transport of the shock-deposited and radioactively-powered radiation through the stellar ejecta. Due
The Nickel Mass Distribution of Stripped-envelope Supernovae: Implications for Additional Power Sources
We perform a systematic study of the 56Ni mass (M Ni) of 27 stripped-envelope supernovae (SESNe) by modeling their light-curve tails, highlighting that use of “Arnett’s rule” overestimates M Ni for
Constraints on the Explosion Timescale of Core-collapse Supernovae Based on Systematic Analysis of Light Curves
The explosion mechanism of core-collapse supernovae is not fully understood yet. In this work, we give constraints on the explosion timescale based on 56Ni synthesized by supernova explosions. First,
The iron yield of normal Type II supernovae
We present Ni mass estimates for 110 normal Type II supernovae (SNe II), computed here from their luminosity in the radioactive tail. This sample consists of SNe from the literature, with at least
Type Ic supernovae from the (intermediate) Palomar Transient Factory
Context. Type Ic supernovae represent the explosions of the most stripped massive stars, but their progenitors and explosion mechanisms remain unclear. Larger samples of observed supernovae can help
The double-peaked Type Ic supernova 2019cad: another SN 2005bf-like object
We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first ∼100 d from explosion. Based on the light-curve morphology, we find that SN 2019cad resembles the
Understanding the extreme luminosity of DES14X2fna
We present DES14X2fna, a high-luminosity, fast-declining type IIb supernova (SN IIb) at redshift z = 0.0453, detected by the Dark Energy Survey (DES). DES14X2fna is an unusual member of its class,
Supernovae Ib and Ic from the explosion of helium stars
Much difficulty has so far prevented the emergence of a consistent scenario for the origin of Type Ib and Ic supernovae (SNe). Either the SN rates or the ejecta masses and composition were in tension
Systematic investigation of the effect of 56Ni mixing in the early photospheric velocity evolution of stripped-envelope supernovae
Mixing of 56Ni, whose nuclear decay energy is a major luminosity source in stripped-envelope supernovae, is known to affect the observational properties of stripped-envelope supernovae such as


Observational and Physical Classification of Supernovae
This chapter describes the current classification scheme of supernovae (SNe). This scheme has evolved over many decades and now includes numerous SN Types and sub-types. Many of these are universally
A meta-analysis of core-collapse supernova56Ni masses
Context.A fundamental property determining the transient behaviour of core-collapse supernovae (CC SNe) is the amount of radioactive56Ni synthesised in the explosion. Using established methods, this
Physics of Luminous Transient Light Curves: A New Relation between Peak Time and Luminosity
Simplified analytic methods are frequently used to model the light curves of supernovae and other energetic transients and to extract physical quantities, such as the ejecta mass and amount of
The Disappearance of the Progenitors of Supernovae 1993J and 2003gd
Using images from the Hubble Space Telescope and the Gemini Telescope, the disappearance of the progenitors of two type II supernovae (SNe) are confirmed and the presence of other stars associated with them is evaluated and it is confirmed that these two supernova were produced by red supergiants.

The optical observations of Ic-4 supernova (SN) 2016coi/ASASSN-16fp, from ∼2 to ∼450  d after explosion, are presented along with analysis of its physical properties. The SN shows the broad lines
The Nickel Mass Distribution of Normal Type II Supernovae
Core-collapse supernova explosions expose the structure and environment of massive stars at the moment of their death. We use the global fitting technique of Pejcha & Prieto (2015a,b) to estimate a

We present the early-phase spectra and the light curves of the broad-lined supernova (SN) 2016coi from $t=7$ to $67$ days after the estimated explosion date. This SN was initially reported as a
Light-curve and spectral properties of ultrastripped core-collapse supernovae leading to binary neutron stars
We investigate light-curve and spectral properties of ultra-stripped core-collapse supernovae. Ultra-stripped supernovae are the explosions of heavily stripped massive stars which lost their
