Helium Accumulation and Thermonuclear Instabilities on Accreting White Dwarfs: From Recurring Helium Novae to Type Ia Supernovae
Yael Hillman, Amir Michaelis, Hagai B. Perets
We investigate helium accumulation on carbon-oxygen (CO) white dwarfs (WDs), exploring a broad parameter space of initial WD masses (--) and helium accretion ra…
It's always the quiet ones: Single Degenerate Double Detonation Type Ia Supernova from Quiescent Helium Accretion
Amir Michaelis, Yael Hillman, Hagai B. Perets
We investigate a sub-Chandrasekhar mass double detonation pathway for Type Ia supernovae arising from single degenerate helium accreting carbon-oxygen white dwarfs. Building on our…
The Role of Binary Configuration in Shaping Nova Evolution via Wind Accretion in Symbiotic Systems
Irin Babu Vathachira, Yael Hillman, Amit Kashi
We investigate the impact of the Bondi--Hoyle--Lyttleton (BHL) accretion mechanism on the evolution of nova eruptions in symbiotic systems by systematically varying three key input…
An optical--mid-infrared color evolution tool for nova identification using WISE data
Joseph Onuegbu, Dafne Guetta, Yael Hillman +2
We present a novel approach for characterizing nova candidates by exploiting the infrared capabilities of the Wide-field Infrared Survey Explorer (WISE) catalog. We developed a pip…
