Dust colour, phase behaviour, and Monte Carlo modelling of interstellar comet 3I/ATLAS from 4 au pre- to 4 au post-perihelion
F. Moreno, M. Serra-Ricart, J. Licandro +4
We report multi-band photometric imaging observations and Monte Carlo dust tail modelling of the interstellar comet 3I/ATLAS covering a wide range of heliocentric distances, from a…
Dust and coma radicals in C/2024 E1 (Wierzchos): evolution of the activity
Irene Mariblanca-Escalona, Pedro J. Gutiérrez, Fernando Moreno +1
We present multi-epoch R-band imaging and long-slit spectroscopy of the dynamically new comet C/2024 E1 (Wierzchos) during its pre-perihelion phase, spanning heliocentric distances…
Dust environment of long-period comet C/2023 A3 (Tsuchinshan-ATLAS)
Fernando Moreno, Charlotte Goetz, Francisco J. Aceituno +3
We present a characterization of the dust environment of long-period comet C/2023 A3 (Tsuchinshan-ATLAS) by analyzing an extensive dataset, including dust tail images and photometr…
Activity of comet 7P/Pons-Winnecke during the 2021 apparition
Irene Mariblanca-Escalona, Luisa M. Lara, Fernando Moreno +2
Comet 7P/Pons-Winnecke was observed from the Calar Alto Observatory (Spain) for four months during the 2021 inbound apparition. Broad-band visible images were taken between 1.71 an…
