Phew, busy morning co-chairing a session in #Spanish (while not speaking any Spanish 😅)! I also brought along my poster from #EePSC2024 to show a bit of my work on #comets #CPESS-8 #PlanetaryScience

That feeling when a marriage to a mere human just won't cut it...my own little spacey artwork, "Bride of the comets".

ASIACO = Asiago Spectroscopy and Imaging Atlas of #COmets: https://arxiv.org/abs/2505.02988 (162 pages) -> "an atlas of cometary imaging and spectroscopy obtained from the Asiago Astrophysical Observatory between 2012 and 2024, still ongoing. Up to now, we monitored 41 comets, acquiring broad-band images using the INAF-OAPd 1.82m Copernico and the 0.67/0.92m Schmidt telescopes, as well as low-to-medium resolution spectra with the DFA-UniPd 1.22m Galileo Telescope."

The #unibern is represented in the Swiss Pavilion at Expo 2025 in Osaka! On display are two Bernese space instruments that are flying on international #space missions into space. And the public also has the opportunity to learn what #comets really smell like: https://mediarelations.unibe.ch/media_releases/2025/media_releases_2025/the_university_of_bern_at_expo_2025_in_osaka/index_eng.html

Dust shells and dark linear structures on dust tails of historical and recent long-period #comets: https://www.aanda.org/articles/aa/full_html/2025/04/aa53986-25/aa53986-25.html -> "in all the cases analyzed, the dust shells form as a result of short-term events characterized by cyclically varying ejection of very small particles from large surface areas on the rotating nucleus. [...] The dark linear stripes along the tail axes may arise from a specific dependence of the ejection speeds on the square root of the cosine of the zenith angle".

were previously unknown! She also found 8 or 9 #comets, as well as making & sharing observations of comets discovered by others. The portrait is based on a miniature of Caroline, as well as her notes & diagrams from 1 August 1786, when she discovered her first comet, now known as Comet C/1786 P1 (Herschel).⁠
⁠
In order to calculate orbits of newly discovered comets, it was important to let other astronomers know ASAP. She discovered her 8th comet while her brother was away.🧵4/5
