Resolving the explosion of supernova 2023ixf in Messier 101 within its complex circumstellar environment
E. A. Zimmerman, I. Irani, P. Chen +54
Observing a supernova explosion shortly after it occurs can reveal important information about the physics of stellar explosions and the nature of the progenitor stars of supernova…
Constraints on neutrino natal kicks from black-hole binary VFTS 243
Alejandro Vigna-Gómez, Reinhold Willcox, Irene Tamborra +8
The recently reported observation of VFTS 243 is the first example of a massive black-hole binary system with negligible binary interaction following black-hole formation. The blac…
Constraints on the multiplicity of the most massive stars known: R136 a1, a2, a3, and c
T. Shenar, H. Sana, P. A. Crowther +5
The most massive stars known to date are R 136 a1, a2, a3, and c within the central cluster R 136a of the Tarantula nebula in the Large Magellanic Cloud (LMC), with reported masses…
A closer look at the binary content of NGC 1850
S. Saracino, S. Kamann, N. Bastian +7
Studies of young clusters have shown that a large fraction of O-/early B-type stars are in binary systems, where the binary fraction increases with mass. These massive stars are pr…
MWC 656 is unlikely to contain a black hole
S. Janssens, T. Shenar, N. Degenaar +4
Context. MWC 656 was reported as the first known Be star with a black-hole (BH) companion in a 60 d period. The mass of the proposed BH companion is estimated to be between 4 - 7 M…
A massive helium star with a sufficiently strong magnetic field to form a magnetar
T. Shenar, G. A. Wade, P. Marchant +13
Magnetars are highly magnetized neutron stars; their formation mechanism is unknown. Hot helium-rich stars with spectra dominated by emission lines are known as Wolf-Rayet stars. W…
Dynamical formation of BH1 in a young star cluster
Sara Rastello, Giuliano Iorio, Michela Mapelli +5
BH1, the first quiescent black hole (BH) detected from data, poses a challenge to most binary evolution models: its current mass ratio is , and its orbi…
Everything that glitters is not gold: V1315 Cas is not a dormant black hole
J. Zak, D. Jones, H. M. J. Boffin +11
The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass invisible companion and…
The B-type Binaries Characterisation Programme II. VFTS 291: A stripped star from a recent mass transfer phase
J. I. Villaseñor, D. J. Lennon, A. Picco +12
Recent studies of massive binaries with putative black hole companions have uncovered a phase of binary evolution that has not been observed before, featuring a bloated stripped st…
Roman CCS White Paper: Characterizing the Galactic population of isolated black holes
Casey Y. Lam, Natasha Abrams, Jeff Andrews +34
Although there are estimated to be 100 million isolated black holes (BHs) in the Milky Way, only one has been found so far, resulting in significant uncertainty about their propert…
A partially stripped massive star in a Be binary at low metallicity: A missing link towards Be X-ray binaries and double neutron star mergers
V. Ramachandran, J. Klencki, A. A. C. Sander +4
Standard binary evolutionary models predict a significant population of core helium-burning stars that lost their hydrogen-rich envelope after mass transfer via Roche-lobe overflow…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
X-Shooting ULLYSES: Massive stars at low metallicity. III. Terminal wind speeds of ULLYSES massive stars
C. Hawcroft, H. Sana, L. Mahy +26
The winds of massive stars have an impact on stellar evolution and on the surrounding medium. The maximum speed reached by these outflows, the terminal wind speed, is a global wind…
Updated radial velocities and new constraints on the nature of the unseen source in NGC1850 BH1
Sara Saracino, Tomer Shenar, Sebastian Kamann +7
A black hole candidate orbiting a luminous star in the Large Magellanic Cloud young cluster NGC 1850 (Myr) has recently been reported based on radial velocity and light cu…
Spectroscopic and evolutionary analyses of the binary system AzV 14 outline paths toward the WR stage at low metallicity
D. Pauli, L. M. Oskinova, W. -R. Hamann +16
The origin of the observed population of Wolf-Rayet (WR) stars in low-metallicity (low-Z) galaxies, such as the Small Magellanic Cloud (SMC), is not yet understood. Standard, singl…
Exploring the influence of different velocity fields on Wolf-Rayet star spectra
Roel R. Lefever, Andreas A. C. Sander, Tomer Shenar +3
Given their strong stellar winds, Wolf-Rayet (WR) stars exhibit emission line spectra that are predominantly formed in expanding atmospheric layers. The description of the wind vel…
Reverse Algols and hydrogen-rich Wolf-Rayet stars from very massive binaries
K. Sen, N. Langer, D. Pauli +6
Massive star feedback affects the evolution of galaxies, where the most massive stars may have the largest impact. The majority of massive stars are born as members of close binary…
