Forming merging double compact objects with stable mass transfer
Annachiara Picco, Pablo Marchant, Hugues Sana +1
Merging double compact objects (CO) represent the inferred sources of every detected gravitational wave (GW) signal, thus modeling their progenitors is important to constrain stell…
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…
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…
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…
Modeling contact binaries, II. The effect of energy transfer
Matthias Fabry, Pablo Marchant, Norbert Langer +1
Context. It is common for massive stars to engage in binary interaction. In close binaries, the components can enter a contact phase, where both stars overflow their respective Roc…
ALMA detection of CO rotational line emission in red supergiant stars of the massive young star cluster RSGC1 -- Determination of a new mass-loss rate prescription for red supergiants
Leen Decin, Anita M. S. Richards, Pablo Marchant +1
[Abridged] Aim: We aim to derive a new mass-loss rate prescription for RSGs that is not afflicted with some uncertainties inherent in preceding studies. Methods: We have observed C…
