Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Åukasz Wyrzykowski, PrzemysÅaw J. MikoÅajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
Rotation Period of C/2006 P1 (McNaught) Through Morphological Analysis with Narrowband Imaging
Vincent Okoth, Cyrielle Opitom, Colin Snodgrass +2
This study presents findings from narrowband imaging of comet C/2006 P1 (McNaught) using the 3.6-metre New Technology Telescope (NTT) at La Silla, Chile. Observations commenced on…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
Recent Chemo-morphological Coma Evolution of Comet 67P/Churyumov-Gerasimenko
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +5
We present VLT/MUSE observations of comet 67P/Churyumov-Gerasimenko during its 2021 perihelion passage, from which we generated simultaneous maps of dust, [OI], C, NH, and…
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…
