Spatially Resolved X-ray Study of Supernova Remnant G306.30.9 with Unusually High Calcium Abundance
Jianbin Weng, Ping Zhou, Yang Chen +6
G306.30.9 is an asymmetric Galactic supernova remnant (SNR), whose progenitor has been thought to be a Type Ia supernova (SN), but its high Ca abundance appears inconsistent wit…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
Final Moments I: Precursor Emission, Envelope Inflation, and Enhanced Mass loss Preceding the Luminous Type II Supernova 2020tlf
Wynn Jacobson-Galán, Luc Dessart, David Jones +33
We present panchromatic observations and modeling of supernova (SN) 2020tlf, the first normal type II-P/L SN with confirmed precursor emission, as detected by the Young Supernova E…
SN2017jgh - A high-cadence complete shock cooling lightcurve of a SN IIb with the Kepler telescope
P. Armstrong, B. E. Tucker, A. Rest +69
SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of the Kepler/K2 mission. Here we present the Kepler/K2 and ground based observations of SN…
SN 2018agk: A Prototypical Type Ia Supernova with a Smooth Power-law Rise in Kepler (K2)
Qinan Wang, Armin Rest, Yossef Zenati +73
We present the 30-min cadence Kepler/K2 light curve of the Type Ia supernova (SN Ia) SN 2018agk, covering approximately one week before explosion, the full rise phase and the decli…
Transients from the Cataclysmic Deaths of Cataclysmic Variables
Brian D. Metzger, Yossef Zenati, Laura Chomiuk +2
We explore the observational appearance of the merger of a low-mass star with a white dwarf (WD) binary companion. We are motivated by Schreiber et al. (2016), who found that multi…
Conserving Local Magnetic Helicity in Numerical Simulations
Yossef Zenati, Ethan T. Vishniac
Magnetic helicity is robustly conserved in systems with very large magnetic Reynolds numbers, including most systems of astrophysical interest, and unlike kinetic and magnetic ener…
HARM3D+NUC: A new method for simulating the post-merger phase of binary neutron star mergers with GRMHD, tabulated EOS and neutrino leakage
Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts +25
The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…
The Early Phases of Supernova 2020pni: Shock-Ionization of the Nitrogen-Enriched Circumstellar Material
G. Terreran, W. V. Jacobson-Galan, J. H. Groh +20
We present multiwavelength observations of the Type II SN 2020pni. Classified at days after explosion, the object showed narrow (FWHM $<250\,\textrm{km}\,\textrm{s}^{-1}…
An Early-Time Optical and Ultraviolet Excess in the type-Ic SN 2020oi
Alexander Gagliano, Luca Izzo, Charles D. Kilpatrick +30
We present photometric and spectroscopic observations of Supernova 2020oi (SN 2020oi), a nearby (17 Mpc) type-Ic supernova (SN Ic) within the grand-design spiral M100. We und…
Transients from ONe White-Dwarf - Neutron-Star/Black-Hole Mergers
Alexey Bobrick, Yossef Zenati, Hagai B. Perets +2
We conduct the first 3D hydrodynamic simulations of oxygen-neon white dwarf-neutron star/black hole mergers (ONe WD-NS/BH mergers). Such mergers constitute a significant fraction,…
Thermonuclear explosion of a massive hybrid HeCO white-dwarf triggered by a He-detonation on a companion
Ruediger Pakmor, Yossef Zenati, Hagai B. Perets +1
Normal type Ia supernovae (SNe) are thought to arise from the thermonuclear explosion of massive ( M) carbon-oxygen white dwarfs (WDs), although the exact mechanism i…
