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…
Polarimetry of Didymos-Dimorphos: Unexpected Long-Term Effects of the DART Impact
Zuri Gray, Stefano Bagnulo, Mikael Granvik +9
We have monitored the Didymos-Dimorphos binary system in imaging polarimetric mode before and after the impact from the Double Asteroid Redirection Test (DART) mission. A previous…
Ejected Particles after Impact Splash on Mars: Aggregates and Aerodynamics
Tim Becker, Jens Teiser, Teresa Jardiel +6
Our earlier laboratory measurements showed that low-velocity sand impacts release fine <5 μm dust from a Martian simulant soil. This dust will become airborne in the Martian atmosp…
Experimental phase function and degree of linear polarization curve of olivine and spinel and the origin of the Barbarian polarization behavior
E. Frattin, J. Martikainen, O. Muñoz +7
We explore experimentally possible explanations of the polarization curves of the sunlight reflected by the Barbarian asteroids. Their peculiar polarization curves are characterize…
Optical spectropolarimetry of binary asteroid Didymos-Dimorphos before and after the DART impact
S. Bagnulo, Z. Gray, M. Granvik +7
We have monitored the Didymos-Dimorphos binary asteroid in spectropolarimetric mode in the optical range before and after the DART impact. The ultimate goal was to obtain constrain…
Releasing Atmospheric Martian Dust in Sand Grain Impacts
Tim Becker, Jens Teiser, Teresa Jardiel +5
Emission of dust up to a few micrometer in size by impacts of sand grains during saltation is thought to be one source of dust within the Martian atmosphere. To study this dust fra…
Polarimetric imaging for the detection of synthetic models of SARS-CoV-2: a proof of concept
Emilio Gomez-Gonzalez, Olga Muñoz, Juan Carlos Gomez-Martin +23
Objective: To conduct a proof-of-concept study of the detection of two synthetic models of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using polarimetric imaging.…
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…
