The spectroscopic binary fraction of the young stellar cluster M17

M. C. Ramírez-Tannus, A. R. Derkink, F. Backs +5

Significant progress has been made toward understanding the formation of massive (M) binaries in close orbits. For example, the detection of a very low velocity d…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

Collisional excitation of propyne (CHCCH) by He atoms

M. Ben Khalifa, B. Darna, J. Loreau

A detailed interpretation of the detected emission lines of environments in which propyne (or methyl acetylene, CHCCH) is observed requires a knowledge of its collisional rate…

The Energy and Dynamics of Trapped Radiative Feedback with Stellar Winds

Sam Geen, Rebekka Bieri, Alex de Koter +2

In this paper, we explore the significant, non-linear impact that stellar winds have on H ii regions. We perform a parameter study using three-dimensional radiative magnetohydrodyn…

A dynamical measure of the black hole mass in a quasar 11 billion years ago

R. Abuter, F. Allouche, A. Amorim +124

Tight relationships exist in the local universe between the central stellar properties of galaxies and the mass of their supermassive black hole. These suggest galaxies and black h…

Rotational excitation of interstellar benzonitrile by helium atoms

M. Ben Khalifa, J. Loreau

Interstellar aromatic molecules such as polycyclic aromatic hydrocarbons and polycyclic nitrogen and oxygen bearing molecules are thought to be abundant in the interstellar medium.…

Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk

Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53

Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
