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-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…
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…
Dynamics of irregularly-shaped cometary particles subjected to outflowing gas and solar radiative forces and torques
Fernando Moreno, Daniel Guirado, Olga Muñoz +6
The dynamics of irregularly-shaped particles subjected to the combined effect of gas drag and radiative forces and torques in a cometary environment is investigated. The equations…
Retrieving Dust Grain Sizes from Photopolarimetry: An Experimental Approach
O. Munoz, E. Frattin, T. Jardiel +8
We present the experimental phase function, degree of linear polarization (DLP), and linear depolarization (deltaL) curves of a set of forsterite samples representative of low-abso…
Dust environment of active asteroids P/2019 A4 (PANSTARRS) and P/2021 A5 (PANSTARRS)
Fernando Moreno, Javier Licandro, Antonio Cabrera-Lavers +2
We report on the characterisation of the dust activity and dynamical evolution of two faint active asteroids, P/2019 A4, and P/2021 A5, observed with the 10.4m GTC using both imagi…
