Binary progenitor systems for Type Ic supernovae [PDF]
Nature CommunicationsCore-collapse supernovae are explosions of massive stars at the end of their evolution. They are responsible for metal production and for halting star formation, having a significant impact on galaxy evolution.

Long-rising Type II Supernovae in the Zwicky Transient Facility Census of the Local Universe
The Astrophysical Journal, 2023 SN 1987A was an unusual hydrogen-rich core-collapse supernova originating from a blue supergiant star. Similar blue supergiant explosions remain a small family of events, and are broadly characterized by their long rises to peak.

Inferring Type II-P Supernova Progenitor Masses from Plateau Luminosities
The Astrophysical Journal Letters, 2023 Connecting observations of core-collapse supernova explosions to the properties of their massive star progenitors is a long-sought, and challenging, goal of supernova science. Recently, Barker et al.

Nucleosynthesis in type II supernovae [PDF]
Nuclear Physics A, 1997 Presupernova evolution and explosive nucleosynthesis in massive stars for main-sequence masses from 13 $M_\odot$ to 70 $M_\odot$ are calculated. We examine the dependence of the supernova yields on the stellar mass, $^{12}C( , ) ^{16}O}$ rate, and explosion energy.

Early Time Spectropolarimetry of the Aspherical Type II Supernova SN 2023ixf
The Astrophysical Journal Letters, 2023 We present six epochs of optical spectropolarimetry of the Type II supernova (SN) 2023ixf ranging from ∼2 to 15 days after the explosion. Polarimetry was obtained with the Kast double spectrograph on the Shane 3 m telescope at Lick Observatory ...

Understanding Type II Supernovae [PDF]
International Astronomical Union Colloquium, 2005 SummaryWe present the results of a systematic analysis of a group of Type II plateau supernovae that span a large range in luminosities, from faint objects like SN 1997D and 1999br to very luminous events like SN 1992am. The physical properties of the supernovae appear to be related to the plateau luminosity or the expansion velocity.

Possible Detection of the Progenitor of the Type II Supernova SN 2023ixf
The Astrophysical Journal Letters, 2023 Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is important to constrain the theory and to justify and design future surveys to ...

SN 2022acko: The First Early Far-ultraviolet Spectra of a Type IIP Supernova
The Astrophysical Journal Letters, 2023 We present five far- and near-ultraviolet spectra of the Type II plateau supernova, SN 2022acko, obtained 5, 6, 7, 19, and 21 days after explosion, all observed with the Hubble Space Telescope/Space Telescope Imaging Spectrograph.

HYDRODYNAMICAL MODELS OF TYPE II PLATEAU SUPERNOVAE [PDF]
The Astrophysical Journal, 2011 We present bolometric light curves of Type II-plateau supernovae (SNe II-P) obtained using a newly developed, one-dimensional Lagrangian hydrodynamic code with flux-limited radiation diffusion. Using our code we calculate the bolometric light curve and photospheric velocities of SN1999em obtaining a remarkably good agreement with observations despite ...
