TL;DR: In this paper, the authors used the radiation thermo-chemical disc code ProDiMo to model the gas and dust in the circumstellar disc of HD 163296, and attempt to determine the disc properties by fitting to observational line and continuum data.
Journal ArticleDOI
H-2 formation on PAHs in photodissociation regions: a high-temperature pathway to molecular hydrogen
TL;DR: In this article, the influence of polycyclic aromatic hydrocarbons (PAHs) on total H2 formation rates in photodissociation regions (PDRs) and assess the effect of these formation rates on the total cloud structure.
Journal ArticleDOI
The formation of massive primordial stars in the presence of moderate uv backgrounds
Muhammad Latif,Dominik R. G. Schleicher,Stefano Bovino,Tommaso Grassi,Tommaso Grassi,Marco Spaans +5 more
TL;DR: In this paper, the impact of UV radiation on fragmentation in primordial halos of a few times 10{sup 7} M {sub ☉] was explored by performing high-resolution cosmological simulations for two distinct halos and vary the strength of the impinging background UV field in units of J {sub 21} assuming a blackbody radiation spectrum with a characteristic temperature of T {sub rad} = 10-sup 4} K.
Journal ArticleDOI
The Stellar Mass Spectrum in Warm and Dusty Gas: Deviations from Salpeter in the Galactic Centre and in Circum-Nuclear Starburst Regions
TL;DR: In this paper, the authors present the first numerical hydrodynamical calculations of stars formed in a molecular region with chemical and thermodynamic properties similar to those of warm and dusty circum-nuclear starburst regions.
