The Massive Progenitor of the Type II-Linear Supernova 2009kr [PDF]
, 2010 We present early-time photometric and spectroscopic observations of supernova (SN) 2009kr in NGC 1832. We find that its properties to date support its classification as Type II-linear (SN II-L), a relatively rare subclass of core-collapse supernovae (SNe)

The Progenitor of the New COMPTEL/ROSAT Supernova Remnant in Vela
, 1999 We show that (1) the newly discovered supernova remnant (SNR), GRO J0852--4642/RX J0852.0--4622, was created by a core-collapse supernova of a massive star, and (2) the same supernova event which produced the $^{44}$Ti detected by COMPTEL from this ...

A Type II Supernova Hubble Diagram from the CSP-I, SDSS-II, and SNLS Surveys [PDF]
, 2016 The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in the vast majority of cases, and hence new methods based solely on ...

Precision Measurement of The Most Distant Spectroscopically Confirmed Supernova Ia with the Hubble Space Telescope [PDF]
, 2013 We report the discovery of a redshift 1.71 supernova in the GOODS North field. The Hubble Space Telescope (HST) ACS spectrum has almost negligible contamination from the host or neighboring galaxies.

Zeeman splitting in structure and composition of ultramagnetized spherical nuclei
Physics Letters B, 2018 Properties and mass distribution of ultramagnetized atomic nuclei that arise in heavy-ion collisions, magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed.

Light echoes - Type II supernovae
The Astrophysical Journal, 1987 Type II supernovae (SNs) light curves show a remarkable range of shapes. Data have been collected for the 12 Type II SNs that have light curve information for more than four months past maximum. Contrary to previous reports, it is found that (1) the decay rate after 100 days past maximum varies by almost an order of magnitude and (2) the light curve ...

Ejection of Supernova-Enriched Gas From Dwarf Disk Galaxies
, 2004 We examine the efficiency with which supernova-enriched gas may be ejected from dwarf disk galaxies, using a methodology previously employed to study the self-enrichment efficiency of dwarf spheroidal systems.

The Peculiar Type II Supernova 1997D: A Case for a Very Low 56Ni Mass [PDF]
, 1998 SN 1997D in NGC 1536 is possibly the least luminous and energetic Type II supernova discovered to date. The entire light curve is subluminous, never reaching MV=-14.65. The radioactive tail follows the 56Co decay slope.

MOLYBDENUM AND RUTHENIUM IN THE GALAXY
Odessa Astronomical Publications, 2018 We present a brief overview of the molybdenum and ruthenium present-day nucleosynthesis calculations and abundance determinations in stars belonging to different substructures (populations) in the Galaxy.
