Circumstellar Medium Interaction in SN 2018lab, A Low-luminosity Type IIP Supernova Observed with TESS

open access: yesThe Astrophysical Journal, 2023
We present photometric and spectroscopic data of SN 2018lab, a low-luminosity Type IIP supernova (LLSN) with a V -band peak luminosity of −15.1 ± 0.1 mag.

Type II supernova energetics

open access: yesThe Astrophysical Journal, 1985
In this paper we exploit the fact that the collapsing core of a massive star, at the endpoint of its thermonuclear life, rapidly becomes hydrostatic after bouncing at nuclear densities. The energy transferred by pdV work from the inner unshocked core as it becomes hydrostatic to the bounce shock in the outer core is, to a good approximation, the ...

Dynamics of Type-II Supernovae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
Hydrodynamical simulations of type-II supernovae in one and two dimensions are performed for the revival phase of the delayed shock by neutrino energy deposition. Starting with a post-collapse model of the 1.31 Mʘ iron core of a 15 Mʘ star immediately after the stagnation of the prompt shock about 10 ms after core bounce, the models are followed for ...

JWST Imaging of the Cartwheel Galaxy Reveals Dust Associated with SN 2021afdx

open access: yesThe Astrophysical Journal Letters, 2023
We present near- and mid-infrared (0.9–18 μ m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its Early Release Observations of the Cartwheel Galaxy.

SNe heating and the chemical evolution of the intra-cluster medium [PDF]

open access: yes, 2002
We compute the chemical and thermal history of the intra-cluster medium in rich and poor clusters under the assumption that supernovae (I, II) are the major responsible both for the chemical enrichment and the heating of the intra-cluster gas.

Type II supernova diversity [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractIt is now firmly established that at a significant fraction of hydrogen-rich type II supernovae (SNe II) arise from red supergiant progenitors. However, a large diversity of SN properties exist, and it is presently unclear how this can be understood in terms of progenitor differences and pre-SN stellar evolution. In this contribution, I present

An updated Type II supernova Hubble diagram [PDF]

open access: yesAstronomy & Astrophysics, 2018
We present photometry and spectroscopy of nine Type II-P/L supernovae (SNe) with redshifts in the 0.045 ≲z≲ 0.335 range, with a view to re-examining their utility as distance indicators. Specifically, we apply the expanding photosphere method (EPM) and the standardized candle method (SCM) to each target, and find that both methods yield distances that ...

The Dusty Red Supergiant Progenitor and the Local Environment of the Type II SN 2023ixf in M101

open access: yesThe Astrophysical Journal Letters, 2023
As one of the closest supernovae (SNe) in the last decade, SN 2023ixf is an unprecedented target to investigate the progenitor star that exploded. However, there is still significant uncertainty in the reported progenitor properties.
