Hydrodynamic Response of Mildly Evolved Common Envelope Donors in Luminous Red Novae
Tenley Hutchinson-Smith, Angela Twum, Enrico Ramirez-Ruiz
Luminous red novae trace unstable binary interactions in which common-envelope evolution can produce either a stellar merger or a surviving binary following envelope ejection. Rece…
Galaxy Zoo Bar Lengths: A Catalogue of Measurements from Hubble Space Telescope Images and the Evolution of Galactic Bar Structure at z < 1
Tenley Hutchinson-Smith, Brooke D. Simmons, Karen L. Masters +12
Understanding the role of galactic scale bars in disk galaxy evolution requires detailed measurements of bar properties across galaxies hosting bars at many redshifts. We present m…
Rethinking Thorne-Żytkow Object Formation: The Fate of X-ray Binary LMC X-4 and Implications for Ultra-long Gamma-ray Bursts
Tenley Hutchinson-Smith, Rosa Wallace Everson, Angela A. Twum +5
We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether a Thorne-Żytkow object (TŻO) might ultimately be assembled. We ana…
Rethinking Thorne-Żytkow Object Formation: Assembly via Common Envelope in Field Binaries
Rosa Wallace Everson, Tenley Hutchinson-Smith, Alejandro Vigna-Gómez +1
Thorne-Żytkow objects (TŻOs), hypothetical merger products in which a neutron star is embedded in a stellar core, are traditionally considered steady-state configurations. Their as…
