An X-ray quiet black hole born with a negligible kick in a massive binary within the Large Magellanic Cloud

Tomer Shenar, Hugues Sana, Laurent Mahy +35

Stellar-mass black holes are the final remnants of stars born with more than 15 solar masses. Billions are expected to reside in the Local Group, yet only few are known, mostly det…

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…

Hubble spectroscopy of LB-1: comparison with B+black-hole and Be+stripped-star models

D. J. Lennon, J. Maíz Apellániz, A. Irrgang +10

LB-1 has variously been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary, or a Be star plus an inflated stripped star (Be+Bstr) binary. The Space Telescope…

Assessing the stellar population and the environment of an HII region on the far side of the Galaxy

A. -N. Chené, R. A. Benjamin, S. Ramírez Alegría +15

We have investigated the stellar and interstellar content of the distant star formation region IRAS 17591-2228 (WISE HII region GAL 007.47+0.06). It is associated to a water maser,…

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…

Analysis of absorption lines in the high resolution spectra of five hot post-AGB candidates

A. Herrero, M. Parthasarathy, S. Simon-Diaz +3

From an analysis of absorption lines in the high resolution spectra we have derived the radial velocities, stellar parameters (Teff, gravity, wind-strength parameter logQ and proje…
