Journal ArticleDOI
The effects of metallicity, radiation field and dust extinction on the charge state of PAHs in diffuse clouds: implications for the DIB carrier
Nick L. J. Cox,Marco Spaans +1 more
TL;DR: In this article, the authors investigated the effects of metallicity, radiation field and extinction curve on the PAH charge state distribution, and thus the theoretical emergent PAH spectrum, in diffuse interstellar clouds.
Journal ArticleDOI
The sequence to hydrogenate coronene cations: A journey guided by magic numbers
Stéphanie Cazaux,Leon Boschman,Nathalie Rougeau,G. Reitsma,Ronnie Hoekstra,Dominique Teillet-Billy,Sabine Morisset,Marco Spaans,Thomas Schlathölter +8 more
TL;DR: In this paper, it was shown that hydrogenation follows a site-specific sequence leading to the appearance of cations having 5, 11, or 17 hydrogen atoms attached, exactly the magic numbers found in the experiments.
Journal ArticleDOI
High-resolution HNC 3-2 SMA observations of Arp220
Susanne Aalto,David J. Wilner,Marco Spaans,Martina C. Wiedner,Kazushi Sakamoto,John H. Black,M. Caldas +6 more
TL;DR: In this paper, the authors present high resolution (0.4) observations of HNC J=3-2 with the SubMillimeter Array (SMA) and find luminous HNC 3-2 line emission in the western part of Arp220, centered on the western nucleus, while the eastern side of the merger shows relatively faint emission.
Journal ArticleDOI
Far-ultraviolet and X-ray irradiated protoplanetary disks : a grid of models I. The disk structure
Rowin Meijerink,Rowin Meijerink,Giambattista Aresu,Inga Kamp,Marco Spaans,W. F. Thi,Peter Woitke +6 more
TL;DR: In this paper, a grid of 240 models is computed in which the X-ray and FUV luminosity, minimum grain size, dust size distribution, and surface density distribution are varied in a systematic way.
Journal ArticleDOI

Laverick,Franck Le Petit,Giacomo Mulas,Evelyne Roueff,Farid Salama,Marco Spaans +34 more
TL;DR: The ESO Diffuse Interstellar Bands Large Exploration Survey (EDIBLES) as discussed by the authors is a large-scale observational survey to characterize the physical and chemical conditions for a statistically significant sample of interstellar lines-of-sight.
