SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
Normal type Ia supernovae from disruptions of hybrid He-CO white-dwarfs by CO white-dwarfs
Hagai B. Perets, Yossef Zenati, Silvia Toonen +1
Type Ia supernovae (SNe) are thought to originate from the thermonuclear explosions of carbon-oxygen (CO) white dwarfs (WDs). The proposed progenitors of standard type Ia SNe have…
Faint rapid red transients from Neutron star -- CO white-dwarf mergers
Yossef Zenati, Alexey Bobrick, Hagai B. Perets
Mergers of neutron stars (NS) and white dwarfs (WD) may give rise to observable explosive transient events. We use 3D hydrodynamical (SPH) simulations, as well as 2D hydrodynamical…
Formation constraints indicate a black-hole accretor in 47 Tuc X9
Ross P. Church, Jay Strader, Melvyn B. Davies +1
The luminous X-ray binary 47 Tuc X9 shows radio and X-ray emission consistent with a stellar-mass black hole accreting from a carbon-oxygen white dwarf. Its location, in the core o…
Mass transfer in white dwarf-neutron star binaries
Alexey Bobrick, Melvyn B. Davies, Ross P. Church
We perform hydrodynamic simulations of mass transfer in binaries that contain a white dwarf and a neutron star (WD-NS binaries), and measure the specific angular momentum of materi…
