A grid of fast-rotating, chemically-homogeneous, supernova and/or long-GRB progenitors
M. Renzo, O. Gottlieb, H. S. Chan +6
The understanding of the mechanism(s) by which massive stars collapse and possibly explode is rapidly maturing. Uncertainties in the structure of the stellar core at the onset of c…
Accretion-induced Collapse of Dark Matter-admixed Rotating White Dwarfs: Dynamics and Gravitational-wave Signals
Ho-Sang Chan, Ming-chung Chu, Shing-Chi Leung
We present two-dimensional hydrodynamic simulations of the accretion-induced collapse (AIC) of rotating white dwarfs admixed with an extended component of dark matter (DM) comprisi…
A New Classification Model for the ZTF Catalog of Periodic Variable Stars
Siu-Hei Cheung, V. Ashley Villar, Ho-Sang Chan +1
Using the second data release from the Zwicky Transient Facility (ZTF, Bellm et al. 2019), Chen et al. (2020) created a ZTF Catalog of Periodic Variable Stars (ZTF CPVS) of 781, 60…
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…
A Convolutional Autoencoder-Based Pipeline for Anomaly Detection and Classification of Periodic Variables
H. S. Chan, S. H. Cheung, V. Ashley Villar +1
The periodic pulsations of stars teach us about their underlying physical process. We present a convolutional autoencoder-based pipeline as an automatic approach to search for out-…
Dark Matter-admixed Rotating White Dwarfs as Peculiar Compact Objects
H-S. Chan, M-C. Chu, S-C. Leung
The discoveries of anomalous compact objects challenge our understanding of the standard theory of stellar structures and evolution. They serve as an excellent laboratory to search…
Delayed Detonation Thermonuclear Supernovae With An Extended Dark Matter Component
H-S. Chan, M-C. Chu, S-C. Leung +1
We present simulations of thermonuclear supernovae admixed with an extended component of fermionic cold dark matter. We consider the explosion of a Chandrasekhar-mass white dwarf u…
