Skye: A Differentiable Equation of State

Adam S. Jermyn, Josiah Schwab, Evan Bauer +2

Stellar evolution and numerical hydrodynamics simulations depend critically on access to fast, accurate, thermodynamically consistent equations of state. We present Skye, a new equ…

EVR-CB-004: An Inflated Hot Subdwarf O star + Unseen WD Companion in a Compact Binary Discovered with the Evryscope

Jeffrey K. Ratzloff, Thomas Kupfer, Brad N. Barlow +10

We present the discovery of EVR-CB-004, a close binary with a remnant stellar core and an unseen white dwarf companion. The analysis in this work reveals the primary is potentially…

A gravitational wave detectable candidate Type Ia supernova progenitor

Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37

Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…

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…

EVR-CB-001: An evolving, progenitor, white dwarf compact binary discovered with the Evryscope

Jeffrey K. Ratzloff, Brad N. Barlow, Thomas Kupfer +7

We present EVR-CB-001, the discovery of a compact binary with an extremely low mass () helium core white dwarf progenitor (pre-He WD) and an unseen low mass…
