High-resolution optical spectroscopy reveals the distinctive volatile composition of the interstellar comet 3I/ATLAS

K. Aravind, E. Jehin, C. Opitom +9

Comets preserve volatile material from the early stages of planetary-system formation. The discovery of the interstellar comet 3I/ATLAS enables a direct comparison between a comet…

Origin and evolution of NiI and FeI in the coma of the interstellar comet 3I/ATLAS throughout its trajectory

Damien Hutsemékers, Jean Manfroid, Cyrielle Opitom +8

We present high-resolution UVES+VLT observations of neutral nickel and iron atoms in the coma of the interstellar comet 3I/ATLAS taken after perihelion. Metal emission was strong s…

Pre-perihelion evolution of the NiI/FeI abundance ratio in the coma of the interstellar comet 3I/ATLAS. From extreme to normal

Damien Hutsemékers, Jean Manfroid, Emmanuël Jehin +9

Emission lines of FeI and NiI are commonly found in the coma of Solar System comets, even at large heliocentric distances. These atoms are most likely released from the surface of…

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…

Comets CO and CO fluorescence models for measuring the C/C isotopic ratio in CO

Philippe Rousselot, Emmanuel Jehin, Damien Hutsemékers +3

Context: CO is an abundant species in comets, creating CO ion with emission lines that can be observed in the optical spectral range. A good modeling of its fluorescence spectr…
