On the Accretion-Fed Growth of Neutron Stars During Common Envelope
Morgan MacLeod, Enrico Ramirez-Ruiz
This paper models the orbital inspiral of a neutron star (NS) through the envelope of its giant-branch companion during a common envelope (CE) episode. These CE episodes are necess…
Asymmetric Accretion Flows within a Common Envelope
Morgan MacLeod, Enrico Ramirez-Ruiz
This paper examines flows in the immediate vicinity of stars and compact objects dynamically inspiralling within a common envelope (CE). Flow in the vicinity of the embedded object…
Compact Stellar Binary Assembly in the First Nuclear Star Clusters and r-Process Synthesis in the Early Universe
Enrico Ramirez-Ruiz, Michele Trenti, Morgan MacLeod +3
Investigations of elemental abundances in the ancient and most metal deficient stars are extremely important because they serve as tests of variable nucleosynthesis pathways and ca…
The History of R-Process Enrichment in the Milky Way
Sijing Shen, Ryan Cooke, Enrico Ramirez-Ruiz +3
We investigate the production sites and the enrichment history of -process elements in the Galaxy, as traced by the [Eu/Fe] ratio, using the high resolution, cosmological zoom-i…
Diversity Of Short Gamma-Ray Burst Afterglows From Compact Binary Mergers Hosting Pulsars
Cole Holcomb, Enrico Ramirez-Ruiz, Fabio De Colle +1
Short gamma-ray bursts (sGRBs) are widely believed to result from the mergers of compact binaries. This model predicts an afterglow that bears the characteristic signatures of a co…
Necessary Conditions for Short Gamma-Ray Burst Production in Binary Neutron Star Mergers
Ariadna Murguia-Berthier, Gabriela Montes, Enrico Ramirez-Ruiz +2
The central engine of short gamma-ray bursts (sGRBs) is hidden from direct view, operating at a scale much smaller than that probed by the emitted radiation. Thus we must infer its…
