Formation of metal-free binaries: Impact of H line cooling and CIE cooling

Rafeel Riaz, Dominik R. G. Schleicher, Stefano Bovino +2

During primordial star formation, the main cooling channel is provided by H and super-molecules, such as H or H, at sufficiently high densities. When the latter f…

Chemical Evolution of Fluorine in the Milky Way

Kate A. Womack, Fiorenzo Vincenzo, Brad K. Gibson +5

Fluorine has many different potential sites and channels of production, making narrowing down a dominant site of fluorine production particularly challenging. In this work, we inve…

Buckyball-metal complexes as promising carriers of astronomical unidentified infrared emission bands

Gao-Lei Hou, Olga V. Lushchikova, Joost M. Bakker +3

Infrared emission bands with wavelengths between 3-20 μm are observed in a variety of astrophysical environments [1,2]. They were discovered in the 1970s and are generally attribut…

The early evolution of young massive clusters: The kinematic history of NGC6611 / M16

Mitchel Stoop, Lex Kaper, Alex de Koter +3

In the first few Myr the massive stars dynamically interact, produce runaways and affect the initial binary population. Observing and interpreting the dynamics of young massive clu…

Deuteration of c-CH towards the pre-stellar core L1544

K. Giers, S. Spezzano, F. Alves +7

Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…

Fine and hyperfine excitation of nitric oxide by collision with para-H2

M. Ben Khalifa, J. Loreau

Nitric oxide is an open-shell molecule abundantly detected in the interstellar medium. A precise modeling of its radiative and collisional processes opens the path to a precise est…
