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…
