Stochasticity in Stellar Yields Reflected in Supernova Dust Masses Across All Massive-Star Progenitors
Archana Purushothaman, Arkaprabha Sarangi, S. K. Jeena
Massive stars, ending their lives as supernovae (SNe), are among the primary sources of dust in galaxies. In this study, we derive theoretical upper limits on dust masses as a func…
The Occurrence and Impact of Carbon-Oxygen Shell Mergers in Massive Stars
L. Roberti, M. Pignatari, H. E. Brinkman +6
In their final stages before undergoing a core-collapse supernova, massive stars may experience mergers between internal shells where carbon (C) and oxygen (O) are consumed as fuel…
Origin of -Poor Very Metal-Poor Stars
S. K. Jeena, Projjwal Banerjee
Among very metal-poor (VMP) stars, -poor VMP (PVMP) stars that have sub-solar values of for Mg and other elements are rare and are thought to have been for…
SDSSJ0018-0939: A Clear Signature of Sub-Chandrasekhar Mass Type 1a Supernova
S. K. Jeena, Projjwal Banerjee
Very metal-poor (VMP) stars () that have sub-solar values of for elements such as Mg, Si, and Ca, are referred to as -poor VMP stars. The…
Origin of LAMOST J1010+2358 Revisited
S. K. Jeena, Projjwal Banerjee
Signature from Pop III massive stars of -- that end their lives as pair-instability supernovae (PISNe) are expected to be seen in very metal-poor (VMP) sta…
On the Core-Collapse Supernova Explanation for LAMOST J1010+2358
S K Jeena, Projjwal Banerjee, Alexander Heger
Low-metallicity very massive stars with an initial mass of -- are expected to end their lives as pair-instability supernovae (PISNe). The abundance p…
