Revealing Optically Hidden Companions to Intermediate-Mass Stripped Stars with Radial Velocities
Alexander Laroche, Maria R. Drout, Ylva Götberg +7
The recent discovery of a population of intermediate-mass helium stars (2-8 ) in the Magellanic Clouds has opened a new observational window into massive binary evol…
Pair-instability evolution and explosions in massive stars
M. Renzo, N. Smith
Very massive stars are radiation pressure dominated. Before running out of viable nuclear fuel, they can reach a thermodynamic state where electron-positron pair-production robs th…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
Pulsational pair-instability supernovae in gravitational-wave and electromagnetic transients
D. D. Hendriks, L. A. C. van Son, M. Renzo +2
Current observations of binary black-hole ({BBH}) merger events show support for a feature in the primary BH-mass distribution at , previously interpr…
Observational predictions for Thorne-Żytkow objects
R. Farmer, M. Renzo, Y. Götberg +3
Thorne-ytkow objects (TO) are potential end products of the merger of a neutron star with a non-degenerate star. In this work, we have computed the first grid of evolutionary…
Strong Variability in AzV 493, an Extreme Oe-Type Star in the SMC
M. S. Oey, N. Castro, M. Renzo +11
We present 18 years of OGLE photometry together with spectra obtained over 12 years, revealing that the early Oe star AzV 493 shows strong photometric (Delta I < 1.2 mag) and spect…
The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus
H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17
Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…
No peaks without valleys: The stable mass transfer channel for gravitational-wave sources in light of the neutron star-black hole mass gap
L. A. C. van Son, S. E. de Mink, M. Renzo +6
Gravitational-wave (GW) detections are starting to reveal features in the mass distribution of double compact objects. The lower end of the black hole (BH) mass distribution is esp…
Resolving The Peak Of The Black Hole Mass Spectrum
Ebraheem Farag, Mathieu Renzo, Robert Farmer +2
Gravitational wave (GW) detections of binary black hole (BH) mergers have begun to sample the cosmic BH mass distribution. The evolution of single stellar cores predicts a gap in t…
Dissecting the microphysics behind the metallicity-dependence of massive stars radii
Chengcheng Xin, Mathieu Renzo, Brian D. Metzger
Understanding the radii of massive stars throughout their evolution is important to answering numerous questions about stellar physics, from binary interactions on the main sequenc…
Rejuvenated accretors have less bound envelopes: Impact of Roche lobe overflow on subsequent common envelope events
M. Renzo, E. Zapartas, S. Justham +5
Common-envelope (CE) evolution is an outstanding open problem in stellar evolution, critical to the formation of compact binaries including gravitational-wave sources. In the ``cla…
SNR G292.0+1.8: A Remnant of a Low-Mass Progenitor Stripped-Envelope Supernova
Tea Temim, Patrick Slane, John C. Raymond +5
We present a study of the Galactic supernova remnant (SNR) G292.0+1.8, a classic example of a core-collapse SNR that contains oxygen-rich ejecta, circumstellar material, a rapidly…
Pair-instability mass loss for top-down compact object mass calculations
M. Renzo, D. D. Hendriks, L. A. C. van Son +1
Population synthesis relies on semi-analytic formulae to determine masses of compact objects from the (helium or carbon-oxygen) cores of collapsing stars. Such formulae are combine…
Searching for Anomalies in the ZTF Catalog of Periodic Variable Stars
H. S. Chan, V. Ashley Villar, S. H. Cheung +4
Periodic variables illuminate the physical processes of stars throughout their lifetime. Wide-field surveys continue to increase our discovery rates of periodic variable stars. Aut…
"Super-Kilonovae" from Massive Collapsars as Signatures of Black-Hole Birth in the Pair-instability Mass Gap
Daniel M. Siegel, Aman Agarwal, Jennifer Barnes +3
The core collapse of rapidly rotating massive ~10 Msun stars ("collapsars"), and resulting formation of hyper-accreting black holes, are a leading model for the central engines of…
The redshift evolution of the binary black hole merger rate: a weighty matter

Gravitational wave detectors are starting to reveal the redshift evolution of the binary black hole (BBH) merger rate, . We make predictions for $R_{\mathrm{BB…
Confirming NGC 6231 as the parent cluster of the runaway high-mass X-ray binary HD 153919/4U 1700-37 with Gaia DR2
Vincent van der Meij, Difeng Guo, Lex Kaper +1
A significant fraction of the most massive stars move through space with a high velocity. One of the possible physical explanations is that a supernova in a compact binary system r…
Evolution of accretor stars in massive binaries: broader implications from modeling ζ Ophiuchi
M. Renzo, Y. Gotberg
Most massive stars are born in binaries close enough for mass transfer episodes. These modify the appearance, structure, and future evolution of both stars. We compute the evolutio…
