A derivation of nano-diamond optical constants: Here be nano-diamonds
A. P. Jones, Nathalie Ysard
% context {Nano-diamonds are an enticing and enigmatic dust component yet their origin is still unclear. They have been unequivocally detected in only a few astronomical objects, y…
The mm-to-cm SED of spiral galaxies. Synergies between NIKA2 and SRT instruments
S. Bianchi, M. Murgia, A. Melis +9
The mm-to-cm range of the Spectral Energy Distribution of spiral galaxies remains largely unexplored. Its coverage is required to disentangle the contribution of dust emission, fre…
First MATISSE L-band observations of HD 179218. Is the inner 10 au region rich in carbon dust particles?
E. Kokoulina, A. Matter, B. Lopez +58
Carbon is one of the most abundant components in the Universe. While silicates have been the main focus of solid phase studies in protoplanetary discs (PPDs), little is known about…
The formation of planetary systems with SPICA
I. Kamp, M. Honda, H. Nomura +38
In this era of spatially resolved observations of planet forming disks with ALMA and large ground-based telescopes such as the VLT, Keck and Subaru, we still lack statistically rel…
Influence of the nano-grain depletion in photon-dominated regions: Application to the gas physics and chemistry in the Horsehead
T. Schirmer, E. Habart, N. Ysard +7
The large disparity in physical conditions from the diffuse interstellar medium (ISM) to denser clouds such as photon-dominated regions (PDRs) triggers an evolution of the dust pro…
Multi-wavelength observations and modelling of a quiescent cloud LDN1512
M. Saajasto, M. Juvela, C. Lefevre +2
Light scattering at near-infrared wavelengths has been used to study the optical properties of the interstellar dust grains, but these studies are limited by the assumptions on the…
