Modeling (Sub-)millimeter Scattering Properties of Fractal and Consolidated Porous Particles: Applications to Protoplanetary Disks
Gonzalo Vargas, Daniel Guirado, Carlos Carrasco-Gonzalez +5
We perform light-scattering numerical simulations for two dust populations: (i) consolidated porous particles computed with the discrete dipole approximation (ADDA) and (ii) highly…

Dust characterization of halos: The extended emission in protoplanetary disks
Sreejita Das, Enrique Macías, Nicolas T. Kurtovic +3
Extended low surface brightness emission has been identified in a number of protoplanetary disks, in tension with predictions of radial drift theory. We aim to investigate the natu…

Exploring Polarized Millimeter Emission from Protoplanetary Disks with Irregular Dust Grains
Jesús Miguel Jáquez-Domínguez, Carlos Carrasco-González, Daniel Guirado +4
Polarization at millimeter wavelengths provides a powerful diagnostic of dust grain properties in protoplanetary disks. Standard models based on solid spherical grains often strugg…
