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…
Experimental phase function and degree of linear polarization of cometary dust analogs
Elisa Frattin, Olga Muñoz, Fernando Moreno +12
We present experimental phase function and degree of linear polarization curves for seven samples of cometary dust analogues namely: ground pieces of Allende, DaG521, FRO95002 and…
Models of Rosetta/OSIRIS 67P dust coma phase function
Fernando Moreno, Daniel Guirado, Olga Muñoz +39
The phase function of the dust coma of comet 67P has been determined from Rosetta/OSIRIS images \citep{Bertini17}. This function show a deep minimum at phase angles near 100$^\circ…
Experimental phase functions of mm-sized cosmic dust grains
O. Muñoz, F. Moreno, F. Vargas-Martín +4
We present experimental phase functions of three types of millimeter-sized dust grains consisting of enstatite, quartz and volcanic material from Mount Etna, respectively. The thre…
Flux and polarization signals of spatially inhomogeneous gaseous exoplanets
T. Karalidi, D. M. Stam, D. Guirado
We present numerically calculated, disk--integrated, spectropolarimetric signals of starlight that is reflected by vertically and horizontally inhomogeneous gaseous exoplanets. We…
