Stars with Plumbing Issues: The Formation of Collimated Outflows on Common-Envelope Simulations and Comparison to Water Fountains Observations
Sarah V. Borges, Philip Chang
Common-envelope evolution (CEE) is one of the biggest open questions in binary stellar evolution, despite being the main channel for the formation of close binaries. One of the mai…

Double White Dwarf Mergers as Progenitors of Long-Period Transients
Manuel Malheiro, Sarah V. Borges, Jaziel G. Coelho +6
There is an ongoing discussion in the literature on the nature of long-period transients (LPTs), radio-emitting sources with periods ranging from hundreds to tens of thousands of s…

A Correlation Between the Final Separation and Mass Ratio from Common Envelope Simulations
Sarah V. Borges
Analytical models for common envelope evolution (CEE), particularly the energy formalism, are used in binary population synthesis to predict post-CEE configurations. This formalism…
