Clumping and X-Rays in cooler B supergiant stars
Matheus Bernini-Peron, Wagner L. F. Marcolino, Andreas A. C. Sander +6
B supergiants (BSGs) are evolved stars with effective temperatures between 10 to 30 kK and are important to understand massive star evolution. Located on the edge of the line-drive…
Towards a self-consistent model of the convective core boundary in upper main sequence stars. Part I: 2.5D and 3D simulations
R. Andrassy, G. Leidi, J. Higl +3
There is strong observational evidence that the convective cores of intermediate-mass and massive main sequence stars are substantially larger than those predicted by standard stel…
The Tarantula Massive Binary Monitoring VI: Characterisation of hidden companions in 51 single-lined O-type binaries, a flat mass-ratio distribution, and black-hole binary candidates
Tomer Shenar, Hugues Sana, Laurent Mahy +10
We aim to hunt for massive binaries hosting a black hole companion (OB+BH) and establish the natal mass-ratio distribution of massive stars at the subsolar metallicity environment…
The R136 star cluster dissected with Hubble Space Telescope/STIS. III. The most massive stars and their clumped winds
Sarah A. Brands, Alex de Koter, Joachim M. Bestenlehner +17
Context: The star cluster R136 inside the LMC hosts a rich population of massive stars, including the most massive stars known. The strong stellar winds of these very luminous star…
From 3D hydrodynamic simulations of common-envelope interaction to gravitational-wave mergers
Melvin M. Moreno, Fabian R. N. Schneider, Friedrich K. Roepke +4
Modeling the evolution of progenitors of gravitational-wave merger events in binary stars faces two major uncertainties: the common-envelope phase and supernova kicks. These two pr…
The young massive SMC cluster NGC 330 seen by MUSE II. Multiplicity properties of the massive-star population
J. Bodensteiner, H. Sana, C. Wang +10
Observations of massive stars in young open clusters (< ~8 Myr) have shown that a majority of them are in binary systems, most of which will interact during their life. Populations…
The Tarantula Massive Binary Monitoring V. R 144: a wind-eclipsing binary with a total mass > 140 Msun
T. Shenar, H. Sana, P. Marchant +21
R 144 is the visually brightest WR star in the Large Magellanic Cloud (LMC). R 144 was reported to be a binary, making it potentially the most massive binary thus observed. We perf…
Simulating the formation of Carinae's surrounding nebula through unstable triple evolution and stellar merger-induced eruption
Ryosuke Hirai, Philipp Podsiadlowski, Stanley P. Owocki +2
Carinae is an extraordinary massive star famous for its 19th century Great Eruption and the surrounding Homunculus nebula ejected in that event. The cause of this eruption has…
The R136 star cluster dissected with Hubble Space Telescope/STIS. II. Physical properties of the most massive stars in R136
Joachim M. Bestenlehner, Paul A. Crowther, Saida M. Caballero-Nieves +11
We present an optical analysis of 55 members of R136, the central cluster in the Tarantula Nebula of the Large Magellanic Cloud. Our sample was observed with STIS aboard the Hubble…
Weighing stars from birth to death: mass determination methods across the HRD
Aldo Serenelli, Achim Weiss, Conny Aerts +31
The mass of a star is the most fundamental parameter for its structure, evolution, and final fate. It is particularly important for any kind of stellar archaeology and characteriza…
The Art of Modeling Stellar Mergers and the Case of the B[e] Supergiant R4 in the Small Magellanic Cloud
Samantha Wu, Rosa Wallace Everson, Fabian R. N. Schneider +2
Most massive stars exchange mass with a companion, leading to evolution which is altered drastically from that expected of stars in isolation. Such systems are the result of unusua…
The Tarantula Massive Binary Monitoring: III. Atmosphere analysis of double-lined spectroscopic systems
L. Mahy, H. Sana, M. Abdul-Masih +17
Accurate stellar parameters of individual objects in binary systems are essential to constrain the effects of binarity on stellar evolution. These parameters serve as a prerequisit…
The Tarantula Massive Binary Monitoring. IV. Double-lined photometric binaries
L. Mahy, L. A. Almeida, H. Sana +10
A high fraction of massive stars are found to be binaries but only a few of them are reported as photometrically variable. By studying the populations of SB2 in the 30 Doradus regi…
Properties of OB star-black hole systems derived from detailed binary evolution models
N. Langer, C. Schürmann, K. Stoll +38
The recent gravitational wave measurements have demonstrated the existence of stellar mass black hole binaries. It is essential for our understanding of massive star evolution to i…
The young massive SMC cluster NGC 330 seen by MUSE. I. Observations and stellar content
J. Bodensteiner, H. Sana, L. Mahy +9
A majority of massive stars are part of binary systems, a large fraction of which will inevitably interact during their lives. Binary-interaction products (BiPs), i.e. stars affect…
How mergers magnetise massive stars
Fabian R. N. Schneider, Sebastian T. Ohlmann, Philipp Podsiadlowski +4
Magnetic fields are ubiquitous in the Universe. The Sun's magnetic field drives the solar wind and causes solar flares and other energetic surface phenomena that profoundly affect…
A census of massive stars in NGC 346. Stellar parameters and rotational velocities
P. L. Dufton, C. J. Evans, I. Hunter +2
Spectroscopy for 247 stars towards the young cluster NGC 346 in the Small Magellanic Cloud has been combined with that for 116 targets from the VLT-FLAMES Survey of Massive Stars.…
Hydrodynamical simulations and similarity relations for eruptive mass loss from massive stars
Stanley P. Owocki, Ryo Hirai, Philipp Podsiadlowski +1
Motivated by the eruptive mass loss inferred from Luminous Blue Variable (LBV) stars, we present 1D hydrodynamical simulations of the response from sudden energy injection into the…
Gaia and HST astrometry of the very massive 150 candidate runaway star VFTS682
M. Renzo, S. E. de Mink, D. J. Lennon +12
How very massive stars form is still an open question in astrophysics. VFTS682 is among the most massive stars known, with an inferred initial mass of 150 . It is l…
Response to comment on "An excess of massive stars in the local 30 Doradus starburst"
F. R. N. Schneider, H. Sana, C. J. Evans +29
Farr and Mandel reanalyse our data, finding initial-mass-function slopes for high mass stars in 30 Doradus that agree with our results. However, their reanalysis appears to underpr…
