Tracing grain growth in the forming prestellar core L1506C with 3D modeling of Herschel, IRAM, and CFHT observations
E. Zhu, I. Ristorcelli, K. Demyk +5
In the early phases of star formation, properties of prestellar cores are commonly inferred from observations of thermal dust emission and thus depend on dust properties, which mus…
Pristine composition or size evolution: Can current dust models reproduce emissivities observed in nearby protostars?
M. -A. Carpine, A. Maury, N. Ysard +1
Interstellar dust is a crucial asset in many astronomical observations. Characterising grains present in the dense gas and in star-forming environments is also key to constrain the…
Spatially-resolved interstellar dust properties in the face-on spiral galaxy M 99 as observed by NIKA2
L. Pantoni, F. Galliano, S. C. Madden +62
Large dust grains in thermal equilibrium dominate the far-infrared and contribute to the millimetre continuum of star-forming galaxies, but constraining their properties is difficu…
JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
From small dust to micron-sized aggregates: the influence of structure and composition on the dust optical properties
M. -A. Carpine, N. Ysard, A. Maury +1
Models of astrophysical dust are key to understand several physical processes, from the role of dust grains as cooling agents in the ISM to their evolution in dense circumstellar d…
