The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…
Discovery of an Edge-on Circumstellar Debris Disk Around BD+45598: a Newly Identifed Member of the Pictoris Moving Group
Sasha Hinkley, Elisabeth C. Matthews, Charlène Lefevre +24
We report the discovery of a circumstellar debris disk viewed nearly edge-on and associated with the young, K1 star BD+45598 using high-contrast imaging at 2.2m obtain…
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…
Evolution of dust porosity through coagulation and shattering in the interstellar medium
Hiroyuki Hirashita, Vladimir B. Il'in, Laurent Pagani +1
The properties of interstellar grains, such as grain size distribution and grain porosity, are affected by interstellar processing, in particular, coagulation and shattering, which…
