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…
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…
The Effect of Donor Star Rejuvenation on Common Envelope Evolution
C. Landri, P. M. Ricker, M. Renzo +2
In close binary star systems, common envelope evolution may occur after a previous phase of mass transfer. Some isolated formation channels for double neutron star binaries suggest…
Stellar triples with chemically homogeneously evolving inner binaries
Andris Dorozsmai, Silvia Toonen, Alejandro Vigna-Gómez +2
Observations suggest that massive stellar triples are common. However, their evolution is not yet fully understood. We investigate the evolution of hierarchical triples in which th…
Mergers prompted by dynamics in compact, multiple-star systems: a stellar-reduction case for the massive triple TIC 470710327
Alejandro Vigna-Gómez, Bin Liu, David R. Aguilera-Dena +3
TIC 470710327, a massive compact hierarchical triple-star system, was recently identified by NASA's Transiting Exoplanet Survey Satellite (TESS). TIC 470710327 is comprised of a co…
Wind mass-loss rates of stripped stars inferred from Cygnus X-1
Coenraad J. Neijssel, Serena Vinciguerra, Alejandro Vigna-Gomez +5
Recent observations of the high-mass X-ray binary Cygnus X-1 have shown that both the companion star (41 solar masses) and the black hole (21 solar masses) are more massive than pr…
Chemically Homogeneous Evolution: A rapid population synthesis approach
Jeff Riley, Ilya Mandel, Pablo Marchant +5
We explore chemically homogeneous evolution (CHE) as a formation channel for massive merging binary black holes (BBHs). We develop methods to include CHE in a rapid binary populati…
Formation pathway for lonely stripped-envelope supernova progenitors: implications for Cassiopeia A
Ryosuke Hirai, Toshiki Sato, Philipp Podsiadlowski +2
We explore a new scenario for producing stripped-envelope supernova progenitors. In our scenario, the stripped-envelope supernova is the second supernova of the binary, in which th…
Common-Envelope Episodes that lead to Double Neutron Star formation
Alejandro Vigna-Gómez, Morgan MacLeod, Coenraad J. Neijssel +6
Close double neutron stars have been observed as Galactic radio pulsars, while their mergers have been detected as gamma-ray bursts and gravitational-wave sources. They are believe…
The effect of the metallicity-specific star formation history on double compact object mergers
Coenraad J. Neijssel, Alejandro Vigna-Gómez, Simon Stevenson +7
We investigate the impact of uncertainty in the metallicity-specific star formation rate over cosmic time on predictions of the rates and masses of double compact object mergers ob…
