SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
Modeling Supernova 2023ixf: Lightcurve Degeneracies and Morphological Differences
Shannon Forde, Jared A. Goldberg
Supernova 2023ixf is a type IIP supernova that was observed in May 2023 in the spiral galaxy Messier 101. This was the closest supernova observed of the decade, making this an exci…
Physics-driven Explosions of Stripped High-Mass Stars: Synthetic Light Curves and Spectra of Stripped-Envelope Supernovae with Broad Lightcurves
Jing Lu, Brandon L. Barker, Jared Goldberg +5
Stripped-envelope supernovae (SESNe) represent a significant fraction of core-collapse supernovae, arising from massive stars that have shed their hydrogen and, in some cases, heli…
One Year of SN 2023ixf: Breaking Through the Degenerate Parameter Space in Light-Curve Models with Pulsating Progenitors
Brian Hsu, Nathan Smith, Jared A. Goldberg +21
We present and analyze the extensive optical broadband photometry of the Type II SN 2023ixf up to one year after explosion. We find that, when compared to two pre-existing model gr…
SN 2021wvw: A core-collapse supernova at the sub-luminous, slower, and shorter end of Type IIPs
Rishabh Singh Teja, Jared A. Goldberg, D. K. Sahu +4
We present detailed multi-band photometric and spectroscopic observations and analysis of a rare core-collapse supernova SN 2021wvw, that includes photometric evolution up to 250 d…
Progenitor with small reaction networks should not be used as initial conditions for core collapse
M. Renzo, J. A. Goldberg, A. Grichener +2
Core collapse initial conditions are a bottleneck in understanding the explosion mechanism(s) of massive stars. Stellar evolution codes struggle after carbon burning, and either st…
Signatures of convection in the atmospheres of cool evolved stars
Andrea Chiavassa, Kateryna Kravchenko, Jared A. Goldberg
Evolved cool stars of various masses are major cosmic engines, delivering substantial mechanical and radiative feedback to the interstellar medium through strong stellar winds and…
Modelling time-dependent convective penetration in 1D stellar evolution
Cole Johnston, Mathias Michielsen, Evan H. Anders +7
1D stellar evolution calculations produce uncertain predictions for quantities like the age, core mass, core compactness, and nucleo-synthetic yields; a key source of uncertainty i…
From Discovery to the First Month of the Type II Supernova 2023ixf: High and Variable Mass Loss in the Final Year before Explosion
Daichi Hiramatsu, Daichi Tsuna, Edo Berger +22
We present the discovery of the Type II supernova SN 2023ixf in M101 and follow-up photometric and spectroscopic observations, respectively, in the first month and week of its evol…
Shock Breakout in 3-Dimensional Red Supergiant Envelopes
Jared A. Goldberg, Yan-fei Jiang, Lars Bildsten
Using Athena++, we perform 3D Radiation-Hydrodynamic calculations of the radiative breakout of the shock wave in the outer envelope of a red supergiant (RSG) which has suffered cor…
Moosinesq Convection in the Cores of Moosive Stars
Evan H. Anders, Evan B. Bauer, Adam S. Jermyn +7
Stars with masses have core convection zones during their time on the main sequence. In these moosive stars, convection…
Numerical Simulations of Convective 3-Dimensional Red Supergiant Envelopes
Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten
We explore the three-dimensional properties of convective, luminous (), Hydrogen-rich envelopes of Red Supergiants (RSGs) based on radiation hydrody…
The electron-capture origin of supernova 2018zd
Daichi Hiramatsu, D. Andrew Howell, Schuyler D. Van Dyk +27
In the transitional mass range ( 8-10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture superno…
Luminous Type II Short-Plateau Supernovae 2006Y, 2006ai, and 2016egz: A Transitional Class from Stripped Massive Red Supergiants
Daichi Hiramatsu, D. Andrew Howell, Takashi J. Moriya +21
The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor's hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plat…
Comparing Moment-Based and Monte Carlo Methods of Radiation Transport Modeling for Type II-Plateau Supernova Light Curves
Benny T. -H. Tsang, Jared A. Goldberg, Lars Bildsten +1
Time-dependent electromagnetic signatures from core-collapse supernovae are the result of detailed transport of the shock-deposited and radioactively-powered radiation through the…
The Value of Progenitor Radius Measurements for Explosion Modeling of Type II-Plateau Supernovae
