Wind Accretion in Massive Binaries Experiencing High Mass Loss Rates: II. Eccentricity
Bhawna Mukhija, Amit Kashi
We perform numerical simulations to investigate high-power wind accretion in massive binary systems undergoing enhanced mass-loss episodes. The primary star is taken in the mass ra…
Envelope Inflation and outflow Driven by Energy Deposition in Massive Stars
Bhawna Mukhija, Amit Kashi
Evolved massive stars are known to undergo outflow with high mass ejections, resulting in the loss of a substantial portion of their envelopes. One proposed mechanism driving these…
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…
Pre-Supernova Multiple Giant Eruptions in Massive Stars
Bhawna Mukhija, Amit Kashi
Massive stars can exhibit giant eruptions with high mass loss shortly before their explosion as a core-collapse Supernova. These multiple giant eruptions (MGEs) may have a commutat…
Wind Accretion in Massive Binaries Experiencing High Mass Loss Rates: I. Dependency on Mass Ratio and Orbital Period
Bhawna Mukhija, Amit Kashi
We run numerical simulations to study high-power wind accretion in a massive binary system during a high mass loss event. The system consists of an evolved primary star with a zero…
High Power Accretion in Massive Binary Systems and the Impact of Metallicity
Bhawna Mukhija, Amit Kashi
During a giant eruption of a very massive star in the binary system, the companion star can accrete a large amount of mass that can change its properties and potentially its subseq…
