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…
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…
Effect of gravity darkening and oblate factor in rapidly rotating massive stars
Bhawna Mukhija, Michel Curé, Ignacio Araya +2
Context. Rapid rotation in massive stars leads to gravity darkening and oblateness, significantly affecting their radiation-driven winds. These effects can alter wind dynamics and…
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…
Accretion and Recovery in Giant Eruptions of Massive Stars
Bhawna Mukhija, Amit Kashi
Giant Eruptions (GEs) are episodic high-rate mass loss events that massive stars experience in the late stage of evolutions before exploding as a core-collapse supernova. If it occ…
Giant Eruptions in Massive Stars and their Effect on the Stellar Structure
Bhawna Mukhija, Amit Kashi
Giant eruptions (GE) in Luminous blue variables (LBVs) are years to decades-long episodes of enhanced mass loss from the outer layers of the star during which the star undergoes ma…
