Triple evolution: an important channel in the formation of type Ia supernovae
Abinaya Swaruba Rajamuthukumar, Adrian Hamers, Patrick Neunteufel +2
Type Ia supernovae (SNe Ia) are thought to be the result of thermonuclear explosions in white dwarfs (WDs). Commonly considered formation pathways include two merging WDs (the doub…
Forming Hot Subluminous Stars from Hierarchical Triples -- I. The Role of an Outer Tertiary on Formation Channels
Holly P. Preece, Adrian S. Hamers, Tiara Battich +1
We present evolutionary pathways for creating hot subdwarf OB (sdOB) stars from hierarchical triple configurations. We use the population synthesis code Multiple Stellar Evolution…
Algebraic and machine learning approach to hierarchical triple-star stability
Pavan Vynatheya, Adrian S. Hamers, Rosemary A. Mardling +1
We present two approaches to determine the dynamical stability of a hierarchical triple-star system. The first is an improvement on the Mardling-Aarseth stability formula from 2001…
The Equilibrium Tide: An Updated Prescription for Population Synthesis Codes
Holly P. Preece, Adrian S. Hamers, Patrick G. Neunteufel +2
We present an updated prescription for the equilibrium tides suitable for population synthesis codes. A grid of 1D evolutionary models was created and the viscous time-scale was ca…
A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar Type Ia supernovae
T. Merle, A. S. Hamers, S. Van Eck +13
Binaries have received much attention as possible progenitors of Type Ia supernova (SNIa) explosions, but long-term gravitational effects in tight triple or quadruple systems could…
