Photometric and spectroscopic monitoring of the outbursting Halley-type comet 12P/Pons-Brooks
Astronomy & AstrophysicsContext. Comet 12P/Pons-Brooks is a Halley-type comet known for its outbursting activity during its previous perihelia in 1883 and 1953. Its strong activity and favourable observing geometry gave a great opportunity to study this outburst-prone comet ...

Water isotopes and hydronium in the evolving coma of 67P
Astronomy & AstrophysicsContext. Cometary isotopes preserve key information about the early Solar System and its presolar heritage. Rosetta’s long-term in situ observations of comet 67P/Churyumov–Gerasimenko offered the first opportunity to examine isotopic variability within a
