From Inspiral to Outburst: Modeling a Potential Luminous Red Nova from Betelgeuse

Naunet Leonhardes-Barboza, Andrea Antoni, Morgan MacLeod +2

Recent evidence suggests that Betelgeuse may host a stellar companion whose orbit will decay through tidal interactions, ultimately leading to engulfment and merger within the next…

How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources

Floor S. Broekgaarden, Ana Lam, Sasha Levina +14

A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…

Hydrodynamic Response of Mildly Evolved Common Envelope Donors in Luminous Red Novae

Tenley Hutchinson-Smith, Angela Twum, Enrico Ramirez-Ruiz

Luminous red novae trace unstable binary interactions in which common-envelope evolution can produce either a stellar merger or a surviving binary following envelope ejection. Rece…

The Landscape of Unstable Mass Transfer in Interacting Binaries and Its Imprint on the Population of Luminous Red Novae

Angela A. G. Twum, Alejandro Vigna-Gómez, Morgan MacLeod +4

A common-envelope (CE) phase occurs when a star engulfs its companion and is widely considered the primary channel for producing Luminous Red Novae (LRNe). In this study, we combin…

Rethinking Thorne-Żytkow Object Formation: The Fate of X-ray Binary LMC X-4 and Implications for Ultra-long Gamma-ray Bursts

Tenley Hutchinson-Smith, Rosa Wallace Everson, Angela A. Twum +5

We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether a Thorne-Żytkow object (TŻO) might ultimately be assembled. We ana…

Molecular gas and star formation in nearby starburst galaxy mergers

Hao He, Connor Bottrell, Christine Wilson +5

We employ the Feedback In Realistic Environments (FIRE-2) physics model to study how the properties of giant molecular clouds (GMCs) evolve during galaxy mergers. We conduct a pixe…

The observability of galaxy merger signatures in nearby gas-rich spirals

Rebecca McElroy, Connor Bottrell, Maan H. Hani +8

Galaxy mergers are crucial to understanding galaxy evolution, therefore we must determine their observational signatures to select them from large IFU galaxy samples such as MUSE a…

Evidence for the preferential disruption of moderately massive stars by supermassive black holes

Brenna Mockler, Angela A. Twum, Katie Auchettl +4

Tidal disruption events (TDEs) provide a unique opportunity to probe the stellar populations around supermassive black holes (SMBHs). By combining light curve modeling with spectra…
