The Eye of Sauron in SN 2025ngs: a Short-plateau Cousin of SN 1998S with Evidence for a Ring-like Circumstellar Medium
Conor L. Ransome, David J. Sand, K. Azalee Bostroem +35
Interacting supernovae probe the twilight years of massive stars, exhibiting signatures of interaction between the supernova ejecta and surrounding material expelled from the proge…
A Luminous Red Supergiant and Dusty Long-period Variable Progenitor for SN 2023ixf
Jacob E. Jencson, Jeniveve Pearson, Emma R. Beasor +23
We analyze pre-explosion near- and mid-infrared (IR) imaging of the site of SN 2023ixf in the nearby spiral galaxy M101 and characterize the candidate progenitor star. The star dis…
A Multi-Year Photopolarimetric Study of the Semi-Regular Variable V CVn and Identification of Analogue Sources
Hilding Neilson, Nicolaus Steenken, John Simpson +4
The semi-regular variable star V Canum Venaticorum (V CVn) is well-known for its unusual linear polarization position angle (PA). Decades of observing V CVn reveal a nearly constan…
Shock shaping? Nebular Spectroscopy of Nova V906 Carinae
É. J. Harvey, E. Aydi, L. Izzo +7
V906 Carinae was one of the best observed novae of recent times. It was a prolific dust producer and harboured shocks in the early evolving ejecta outflow. Here, we take a close lo…
Modeling the Optical to Ultraviolet Polarimetric Variability from Thomson Scattering in Colliding Wind Binaries
Richard Ignace, Andrew Fullard, Manisha Shrestha +5
Massive star binaries are critical laboratories for measuring masses and stellar wind mass-loss rates. A major challenge is inferring viewing inclination and extracting information…
New mass estimates for massive binary systems: a probabilistic approach using polarimetric radiative transfer
Andrew G. Fullard, John T. O'Brien, Wolfgang E. Kerzendorf +4
Understanding the evolution of massive binary stars requires accurate estimates of their masses. This understanding is critically important because massive star evolution can poten…
Polarization simulations of stellar wind bow shock nebulae. II. The case of dust scattering
Manisha Shrestha, Hilding R. Neilson, Jennifer L. Hoffman +2
We study the polarization produced by scattering from dust in a bow shock-shaped region of enhanced density surrounding a stellar source, using the Monte Carlo radiative transfer c…
Polarization simulations of stellar wind bow shock nebulae. I. The case of electron scattering
Manisha Shrestha, Hilding R. Neilson, Jennifer L. Hoffman +1
Bow shocks and related density enhancements produced by the winds of massive stars moving through the interstellar medium provide important information regarding the motions of the…
