Properties of Core Collapse Supernovae from Binary Population Synthesis

Mark Martinez, Anna O'Grady, Katelyn Breivik +1

Core collapse supernovae (CCSNe) impact many areas of astrophysics, including compact object formation and gravitational waves, but many uncertainties remain in our understanding o…

Binarity at LOw Metallicity (BLOeM): The multiplicity properties and evolution of BAF-type supergiants

L. R. Patrick, D. J. Lennon, F. Najarro +36

Given the uncertain evolutionary status of blue supergiant stars, their multiplicity properties hold vital clues to better understand their origin and evolution. As part of The Bin…

Thorne-Żytkow Objects

Anna J. G. O'Grady, Takashi J. Moriya, Mathieu Renzo +1

Interacting binary star systems play a critical role in many areas of astrophysics. One interesting example of a binary merger product are Thorne-Żytkow Objects (TŻOs), stars that…

Binary Yellow Supergiants in the Magellanic Clouds I: Photometric Candidate Identification

Anna J. G. O'Grady, Maria R. Drout, Kathryn F. Neugent +3

Recent works have constrained the binary fraction of evolved populations of massive stars in local galaxies such as red supergiants and Wolf-Rayet stars, but the binary fraction of…

Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment

Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23

We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…

Discovery of the missing intermediate-mass helium stars stripped in binaries

M. R. Drout, Y. Götberg, B. A. Ludwig +4

The theory of binary evolution predicts that many massive stars should lose their hydrogen-rich envelopes via interaction with a companion -- revealing hot helium stars with masses…

Cool, Luminous, and Highly Variable Stars in the Magellanic Clouds. II: Spectroscopic and Environmental Analysis of Thorne-Żytkow Object and Super-AGB Star Candidates

Anna J. G. O'Grady, Maria R. Drout, B. M. Gaensler +9

In previous work we identified a population of 38 cool and luminous variable stars in the Magellanic Clouds and examined 11 in detail in order to classify them as either Thorne-Żyt…

Searching for Anomalies in the ZTF Catalog of Periodic Variable Stars

H. S. Chan, V. Ashley Villar, S. H. Cheung +4

Periodic variables illuminate the physical processes of stars throughout their lifetime. Wide-field surveys continue to increase our discovery rates of periodic variable stars. Aut…

Cool, Luminous, and Highly Variable Stars in the Magellanic Clouds from ASAS-SN: Implications for Thorne-Żytkow Objects and Super-Asymptotic Giant Branch Stars

Anna J. G. O'Grady, Maria R. Drout, B. J. Shappee +9

Stars with unusual properties can provide a wealth of information about rare stages of stellar evolution and exotic physics. However, determining the true nature of peculiar stars…
