The Ice Chemistry in Comets and Planet-forming Disks: Statistical Comparison of CH3OH, H2CO, and NH3 Abundance Ratios
Autor: Manuela Lippi, Linda Podio, Claudio Codella, Sara Faggi, Marta De Simone, Geronimo L. Villanueva, Michael J. Mumma, Cecilia Ceccarelli
Publikováno v: The Astrophysical Journal Letters, Vol 970, Iss 1, p L5 (2024)
Comets are frozen remnants of our solar system’s formation, and comparing their chemical composition to that of planet-forming systems can reveal crucial insights about our origins, potentially answering one of the most challenging questions in pla

Strongly Depleted Methanol and Hypervolatiles in Comet C/2021 A1 (Leonard): Signatures of Interstellar Chemistry?
Autor: Sara Faggi, Manuela Lippi, Michael J. Mumma, Geronimo L. Villanueva
Publikováno v: The Planetary Science Journal, Vol 4, Iss 1, p 8 (2023)
We measured the chemical composition of comet C/2021 A1 (Leonard) using the long-slit echelle grating spectrograph iSHELL/IRTF on 2021 December 20 and on 2022 January 8 and 9. We sampled 11 primary volatiles (H _2 O, HCN, NH _3 , CO, C _2 H _2 , C _2

Global maps of H2O, HCl and isotopic signatures in the Martian atmosphere: synergies between NASA/IRTF and TGO/ExoMars observations
Autor: Sara Faggi, Shohei Aoki, Giuliano Liuzzi, Hideo Sagawa, Michael J. Mumma, Geronimo L. Villanueva
The first detection of HCl in the atmosphere of Mars was recently achieved by the IR spectrometers (ACS and NOMAD) onboard the ExoMars Trace Gas Orbiter (TGO), revealing the presence of chlorine species in the Martian atmosphere. The two instruments

The Extraordinary Passage of Comet C/2020 F3 NEOWISE: Evidence for Heterogeneous Chemical Inventory in Its Nucleus
Autor: Camillus F. Buzard, Gregory Doppmann, Geoffrey A. Blake, Manuela Lippi, Sara Faggi, Michael J. Mumma, Geronimo L. Villanueva, Maria N. Camarca
Upon its discovery in 2020 March, we requested Director Discretionary Time (DDT) at the NASA/IRTF facility to observe comet C/2020 F3 (NEOWISE), with the high-resolution spectrograph iSHELL. The comet approached the Sun, down to 0.3 au, in early 2020

Methane (CH4) on Mars has attracted a great deal of attention since it was first detected in January 2003. As methane is considered a potential marker for past/present biological or geological activity, any possible detection would require evidence w
