Parent Volatile Outgassing Associations in Cometary Nuclei: Synthesizing Rosetta Measurements and Ground-based Observations

Autor: Mohammad Saki, Dennis Bodewits, Boncho P. Bonev, Neil Dello Russo, Adrienn Luspay-Kuti, John W. Noonan, Michael. R. Combi, Yinsi Shou

Publikováno v: The Planetary Science Journal, Vol 5, Iss 3, p 70 (2024)

Comets, as remnants of the solar system’s formation, vary in volatile-refractory content. In situ comet studies, such as the Rosetta mission to 67P/Churyumov–Gerasimenko, provide detailed volatile composition insights, while ground-based studies

The Return of the Rosetta Target: Keck Near-infrared Observations of Comet 67P/Churyumov–Gerasimenko in 2021

Publikováno v: The Astronomical Journal, Vol 166, Iss 6, p 233 (2023)

High-resolution near-infrared ground-based spectroscopic observations of comet 67P/Churyumov–Gerasimenko near its maximum activity in 2021 were conducted from the W. M. Keck Observatory, using the facility spectrograph NIRSPEC. 67P is the best-stud

Coma Abundances of Volatiles at Small Heliocentric Distances: Compositional Measurements of Long-period Comet C/2020 S3 (Erasmus)

Autor: Chemeda Ejeta, Erika Gibb, Nathan Roth, Michael A. DiSanti, Neil Dello Russo, Mohammad Saki, Adam J. McKay, Hideyo Kawakita, Younas Khan, Boncho P. Bonev, Ronald J. Vervack Jr., Michael R. Combi

Publikováno v: The Astronomical Journal, Vol 167, Iss 1, p 32 (2023)

We report production rates of H _2 O and nine trace molecules (C _2 H _6 , CH _4 , H _2 CO, CH _3 OH, HCN, NH _3 , C _2 H _2 , OCS, and CO) in long-period comet C/2020 S3 (Erasmus) using the high-resolution, cross-dispersed infrared spectrograph (iSH

Imaging Lunar Craters with the Lucy Long Range Reconnaissance Imager (L’LORRI): A Resolution Test for NASA's Lucy Mission

Autor: Stuart J. Robbins, E. Beau Bierhaus, Olivier Barnouin, Tod R. Lauer, John Spencer, Simone Marchi, Harold A. Weaver, Stefano Mottola, Hal Levison, Neil Dello Russo

Publikováno v: The Planetary Science Journal, Vol 4, Iss 12, p 234 (2023)

NASA's Lucy mission is designed to better understand the unique population of Trojan asteroids. Trojans were probably captured in Jupiter's L4 and L5 points early in the solar system's evolution and little altered since then. A critical investigation

Direct Simulation Monte Carlo Modeling of Ammonia in Comet C/2014 Q2 (Lovejoy)

Autor: Hideyo Kawakita, Neil Dello Russo, Ronald J. Vervack Jr., Michael A. DiSanti, Boncho P. Bonev, Hitomi Kobayashi, Daniel C. Boice, Yoshiharu Shinnaka

Publikováno v: The Astronomical Journal, Vol 166, Iss 5, p 207 (2023)

Ammonia (NH _3 ), likely the most abundant nitrogen-bearing molecule in cometary ices followed by hydrogen cyanide, is believed to be stored in the nucleus predominantly as a parent ice. However, spatial profiles of NH _3 observed in comet C/2014 Q2

Comprehensive Study of the Chemical Composition and Spatial Outgassing Behavior of Hyperactive Comet 46P/Wirtanen Using Near-IR Spectroscopy during its Historic 2018 Apparition

Autor: Younas Khan, Erika L. Gibb, Nathan X. Roth, Michael A. DiSanti, Neil Dello Russo, Boncho P. Bonev, Chemeda T. Ejeta, Mohammad Saki, Ronald J. Vervack Jr., Adam J. McKay, Hideyo Kawakita, Michael R. Combi, Danna Qasim, Yinsi Shou

Publikováno v: The Astronomical Journal, Vol 165, Iss 6, p 231 (2023)

We present a comprehensive analysis of the chemical composition of the Jupiter-family comet and potential spacecraft target 46P/Wirtanen, in the near-IR wavelength range. We used iSHELL at the NASA Infrared Telescope Facility to observe the comet on

Comets in Context: Comparing Comet Compositions with Protosolar Nebula Models

Autor: Karen Willacy, Neal Turner, Boncho Bonev, Erika Gibb, Neil Dello Russo, Michael DiSanti, Ronald J. Vervack Jr., Nathan X. Roth

Publikováno v: The Astrophysical Journal. 931:164

Comets provide a valuable window into the chemical and physical conditions at the time of their formation in the young solar system. We seek insights into where and when these objects formed by comparing the range of abundances observed for nine mole
