Identifying Thorne-Żytkow Objects through Neutrinos
Pablo MartÃnez-Miravé, Irene Tamborra, Alejandro Vigna-Gómez
Thorne-Å»ytkow Objects (TÅ»Os) have been predicted to form when a neutron star is engulfed by a diffuse, convective giant envelope. Accretion onto a neutron star at a rate that is…
Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
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-Å»ytkow object (TÅ»O) might ultimately be assembled. We a…
Development of convective envelopes in massive stars: Implications for gravitational wave sources
Amedeo Romagnolo, Jakub Klencki, Alejandro Vigna-Gomez +1
The structure of stellar envelopes strongly influences the course and outcome of binary mass transfer, in particular of common envelope (CE) evolution. Convective envelopes can mos…
Stripped helium-star and compact object binaries in coeval populations -- predictions based on detailed binary evolution models
Chen Wang, Julia Bodensteiner, Xiao-Tian Xu +9
Massive stars mainly form in close binaries, where their mutual interactions can profoundly alter their evolutionary paths. Evolved binaries consisting of a massive OB-type main-se…
