Semi-analytical Light Curve Model for Transients Preceding Binary Mergers. I: Supernova Precursor Emission from Compact Object Companions
Daichi Tsuna, Morgan Macleod, V. Ashley Villar
A binary undergoing dynamically unstable mass transfer could rapidly shrink its orbit and lead to a merger, with the whole process often observable in human timescales. We construc…
Evolution of the ZTF SLRN-2020 star-planet merger
Ricardo Yarza, Morgan MacLeod, Benjamin Idini +2
We model the optical and infrared transient ZTF SLRN-2020, previously associated with a star-planet merger. We consider the scenario in which orbital decay via tidal dissipation le…
Evidence for an Instability-Induced Binary Merger in the Double-Peaked, Helium-Rich Type IIn Supernova 2023zkd
A. Gagliano, V. A. Villar, T. Matsumoto +42
We present ultraviolet to infrared observations of the extraordinary Type IIn supernova 2023zkd (SN 2023zkd). Photometrically, it exhibits persistent and luminous precursor emissio…
The Energy Sharing Timescale in an Analytic Framework for Common Envelope Hydrodynamics
Rosa Wallace Everson, Morgan MacLeod, Enrico Ramirez-Ruiz
We propose a new predictive theory for the analysis of common envelope (CE) events which incorporates the effects of relevant hydrodynamical processes into a simple analytical fram…
Observations of Stellar-Mass Black Holes in the Galaxy
Morgan MacLeod, Jonathan Grindlay
Stellar-mass black holes (BHs), with masses comparable to stars, are a major constituent of our Milky Way galaxy. This chapter describes the landscape of challenging, and long-soug…
The Evolution of Binaries under the Influence of Radiation-Driven Winds from a Stellar Companion
Sophie Lund Schrøder, Morgan MacLeod, Enrico Ramirez-Ruiz +4
Interacting binaries are of general interest as laboratories for investigating the physics of accretion, which gives rise to the bulk of high-energy radiation in the Galaxy. They a…
