The Rise of Nova V1674 Herculis
Robert M. Quimby, Brian D. Metzger, Ken J. Shen +3
Observational constraints on classical novae are heavily biased to phases near optical peak and later because of the simple fact that novae are not typically discovered until they…
The Q Branch Cooling Anomaly Can Be Explained by Mergers of White Dwarfs and Subgiant Stars
Ken J. Shen, Simon Blouin, Katelyn Breivik
Gaia's exquisite parallax measurements allowed for the discovery and characterization of the Q branch in the Hertzsprung-Russell diagram, where massive C/O white dwarfs (WDs) pause…
SN 2022joj: A Potential Double Detonation with a Thin Helium shell
E. Padilla Gonzalez, D. A. Howell, G. Terreran +34
We present photometric and spectroscopic data for SN 2022joj, a nearby peculiar Type Ia supernova (SN Ia) with a fast decline rate ( mag). SN 2022joj shows exce…
SN 2022joj: A Peculiar Type Ia Supernova Possibly Driven by an Asymmetric Helium-shell Double Detonation
Chang Liu, Adam A. Miller, Samuel J. Boos +28
We present observations of SN 2022joj, a peculiar Type Ia supernova (SN Ia) discovered by the Zwicky Transient Facility (ZTF). SN 2022joj exhibits an unusually red $g_\mathrm{ZTF}-…
The fastest stars in the Galaxy
Kareem El-Badry, Ken J. Shen, Vedant Chandra +18
We report a spectroscopic search for hypervelocity white dwarfs (WDs) that are runaways from Type Ia supernovae (SNe Ia) and related thermonuclear explosions. Candidates are select…
Type Ia Supernova Nucleosynthesis: Metallicity-Dependent Yields
James D Keegans, Marco Pignatari, Richard J Stancliffe +7
Type Ia supernova explosions (SNIa) are fundamental sources of elements for the chemical evolution of galaxies. They efficiently produce intermediate-mass (with Z between 11 and 20…
