On the origin of O and other volatile species in comets
Vianney Taquet, Kenji Furuya, Catherine Walsh +1
Molecular oxygen, O, was recently detected in comet 67P by the ROSINA instrument on board the Rosetta spacecraft with a surprisingly high abundance of 4 % relative to HO, m…
The Detection of Hot Molecular Cores in the Small Magellanic Cloud
Takashi Shimonishi, Kei E. I. Tanaka, Yichen Zhang +1
We report the first detection of hot molecular cores in the Small Magellanic Cloud, a nearby dwarf galaxy with 0.2 solar metallicity. We observed two high-mass young stellar object…
Spatially resolving the volatile sulfur abundance in the HD 100546 protoplanetary disk
Luke Keyte, Mihkel Kama, Ko-Ju Chuang +5
Volatile elements play a crucial role in the formation of planetary systems. Their abundance and distribution in protoplanetary disks provide vital insights into the connection bet…
The cometary composition of a protoplanetary disk as revealed by complex cyanides
Karin I. Oberg, Viviana V. Guzman, Kenji Furuya +5
Observations of comets and asteroids show that the Solar Nebula that spawned our planetary system was rich in water and organic molecules. Bombardment brought these organics to the…
An Enriched Methane D/H Ratio in the Interstellar Object 3I/ATLAS
Nathan X. Roth, Martin Cordiner, Stefanie Milam +15
Interstellar objects are interlopers from other planetary systems, and their volatile compositions provide a glimpse into planet formation around their host star. We present near-i…
MAGellanic Outflow and chemistry Survey (MAGOS): Hot cores in the LMC
Takashi Shimonishi, Kei E. I. Tanaka, Yichen Zhang +3
The Large Magellanic Cloud (LMC) provides a key laboratory for exploring the diversity of star formation and interstellar chemistry under subsolar metallicity conditions. We presen…
