Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…
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…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
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…
The Long Night: Modeling the Climate of Westeros
Adiv Paradise, Alysa Obertas, Anna O'Grady +1
Many previous authors have attempted to find explanations for Westeros's climate, characterized by a generally moderate, Earth-like climate punctuated by extremely long and cold wi…
Models and Simulations for the Photometric LSST Astronomical Time Series Classification Challenge (PLAsTiCC)
R. Kessler, G. Narayan, A. Avelino +26
We describe the simulated data sample for the "Photometric LSST Astronomical Time Series Classification Challenge" (PLAsTiCC), a publicly available challenge to classify transient…
Unstable marginally outer trapped surfaces in static spherically symmetric spacetimes
Ivan Booth, Hari K. Kunduri, Anna O'Grady
We examine potential deformations of inner black hole and cosmological horizons in Reissner-Nordström de-Sitter spacetimes. While the rigidity of the outer black hole horizon is gu…
