Activity and composition of periodic comets 67P/Churyumov-Gerasimenko and 103P/Hartley 2 at two different perihelion passages
E. Hemmen, M. Vander Donckt, E. Jehin +6
Through photometry and spectroscopy, we studied the evolution of the activity and chemical composition of comet 67P during its 2025 and 2021 perihelion passages and of comet 103P d…
Long-term monitoring of a dynamically new comet C/2020 V2 (ZTF)
Goldy Ahuja, K. Aravind, Shashikiran Ganesh +5
Comet C/2020 V2 (ZTF) is categorized as a dynamically new long-period comet, making its first approach to the inner Solar system. We have observed this comet for around 32 months (…
Variations in Volatile-Driven Activity of Comet C/2017 K2 (PanSTARRS) Revealed by Long-Term Multi-Wavelength Observations
S. Hmiddouch, E. Jehin, M. Lippi +7
Context. A comprehensive study of comets over a wide heliocentric distance range helps us understand the physical processes driving their activity and reveals compositional differe…
Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum
Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…
Activity and composition of the hyperactive comet 46P/Wirtanen during its close approach in 2018
Y. Moulane, E. Jehin, J. Manfroid +10
Hyperactive comets are a small group of comets whose activity are higher than expected. They seem to emit more water than they should based on the size of their nucleus and comet 4…
