The Evolution of the Type Ia Supernova Luminosity Function
Ken J. Shen, Silvia Toonen, Or Graur
Type Ia supernovae (SNe Ia) exhibit a wide diversity of peak luminosities and light curve shapes: the faintest SNe Ia are 10 times less luminous and evolve more rapidly than the br…
Short Gamma-Ray Bursts following mergers of an ONeMg with a CO white dwarf
Maxim Lyutikov, Silvia Toonen
We discuss a scenario of short Gamma-Ray Bursts (GRBs) following a merger of a massive ONeMg white dwarf (WD) with a CO WD, and an ensuing accretion induced collapse (AIC). An init…
The rate of WD-WD head-on collisions in isolated triples is too low to explain standard type Ia supernovae
S. Toonen, H. B. Perets, A. S. Hamers
Type Ia supernovae (Ia-SNe) are thought to arise from the thermonuclear explosions of white dwarfs (WDs). The progenitors of such explosions are still highly debated; in particular…
The binarity of the local white dwarf population
S. Toonen, M. Hollands, B. T. Gaensicke +1
White dwarfs (WDs) are powerful tools to study the evolutionary history of stars and binaries in the Galaxy. But do we understand their multiplicity from a theoretical point of vie…
Prospects for detection of detached double white dwarf binaries with Gaia, LSST and LISA
Valeriya Korol, Elena M. Rossi, Paul J. Groot +3
Double white dwarf (DWD) binaries are expected to be very common in the Milky Way, but their intrinsic faintness challenges the detection of these systems. Currently, only a few te…
