The bound origin of low-mass stellar binaries
A. Generozov, S. S. R. Offner, K. M. Kratter +3
Most main sequence stars, unlike our Sun, belong to multiple systems with two or more stars. How and when these multiples come together and become bound is uncertain, since the ear…
The Single-Degenerate Channel Leads to Type Iax and Not Type Ia Supernovae due to Premature Ignition
Amir Michaelis, Hagai B. Perets
Type Ia supernovae (SNe Ia) are a critical tool for cosmology and galactic enrichment, yet the progenitor systems of normal SNe Ia remain a central puzzle. The long-debated single-…
An interferometric study of B star multiplicity
A. J. Frost, H. Sana, J-B Le Bouquin +7
Massive stars can have extreme effects on their environments from local to galactic scales. While O star multiplicity has been studied over a broad separation range (to the point w…
A Triple Scenario for the Formation of Wide Black Hole Binaries Such As Gaia BH1
A. Generozov, H. B. Perets
Recently, several non-interacting black hole-stellar binaries have been identified in Gaia data. For example, Gaia BH1, where a Sun-like star is in a moderate eccentricity (e=0.44)…
Hyper-runaway and hypervelocity white dwarf candidates in \textit{Gaia} Data Release 3: possible remnants from Ia/Iax supernova explosions or dynamical encounters
Andrei P. Igoshev, Hagai Perets, Na'ama Hallakoun
Type Ia and other peculiar supernovae (SNe) are thought to originate from the thermonuclear explosions of white dwarfs (WDs). Some of the proposed channels involve the ejection of…
3D Hydrodynamical Simulations of Helium-Ignited Double-degenerate White Dwarf Mergers
Niranjan Roy, Vishal Tiwari, Alexey Bobrick +6
The origins of type Ia supernovae (SNe Ia) are still debated. Some of the leading scenarios involve a double detonation in double white dwarf (WD) systems. In these scenarios, heli…
Compact objects formation, retention, and growth through accretion onto gas-embedded white-dwarfs/neutron-stars in gas-enriched globular-clusters
Hagai B. Perets
Observations of pulsars in globular clusters (GCs) give evidence that more >10-20% of neutron stars (NSs) ever formed in GCs were retained there. However, the velocity distribution…
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…
The Origins of Blue Stragglers and Binarity in Globular Clusters
Nathan Leigh, Christian Knigge, Alison Sills +3
(abridged) We use newly available empirical binary fractions for globular clusters to carry out a direct test of the binary evolution hypothesis, and of collisional channels that i…
