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…

Exploring Polarized Millimeter Emission from Protoplanetary Disks with Irregular Dust Grains
Jesús Miguel Jáquez-DomÃnguez, 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…

Photoionization modelling of circumstellar nebulae using irregular grains
P. Jiménez-Hernández, S. J. Arthur, D. Guirado +4
We study the effects of using the optical properties of irregular hexahedral grains in photoionization models of circumstellar nebulae around evolved stars. Dust opacities for the…
