Centimeter-wave OH observations of comets 12P/Pons-Brooks and C/2023 A3 (Tsuchinshan-ATLAS) with FAST
Long-Fei Chen, Juncen Li, Zhen Wang +5
We present centimeter-wave spectroscopic observations of the OH 18-cm lines in two bright comets, 12P/Pons-Brooks and C/2023 A3 (Tsuchinshan-ATLAS), conducted with the Five-hundred…
Perihelion Asymmetry in the Water Production Rate of the Interstellar Object 3I/ATLAS
Hanjie Tan, Xiaoran Yan, Jian-Yang Li
3I/ATLAS is an interstellar object whose activity provides critical insights into its composition and origin. However, due to its orbital geometry, the object is too close to the S…
Composition and Space Weathering Characteristics of Tianwen-2 Mission's First Target Near-Earth Asteroid (469219) Kamo`oalewa
Minge Liu, Yazhou Yang, Yang Liu +4
The near-Earth asteroid Kamo`oalewa, a quasi-satellite of the Earth and the target for sample return by China's Tianwen-2 mission, exhibits distinctive spectral characteristics. Th…
Pre-perihelion radio observations of comet 12P/Pons-Brooks with Tianma radio telescope
Juncen Li, Xian Shi, Jianchun Shi +7
{The multiple outburst events of comet 12P/Pons-Brooks during its 2024 apparition offer a unique window into highly-active volatile releasing processes not observable during quiesc…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
FAST Observations of Four Comets to Search for the Molecular Line Emissions between 1.0 and 1.5 GHz Frequencies
Long-Fei Chen, Chao-Wei Tsai, Jian-Yang Li +11
We used the Five-hundred-meter Aperture Spherical radio Telescope (FAST) to search for the molecular emissions in the L-band between 1.0 and 1.5 GHz toward four comets, C/2020 F3 (…
VLT/MUSE Characterisation of Dimorphos Ejecta from the DART Impact
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +8
We have observed the Didymos-Dimorphos binary system with the MUSE integral field unit spectrograph mounted at the Very Large Telescope (VLT) pre and post-DART impact, and captured…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Characterization of the ejecta from NASA/DART impact on Dimorphos: observations and Monte Carlo models
Fernando Moreno, Adriano Campo Bagatin, Gonzalo Tancredi +26
The NASA/DART (Double Asteroid Redirection Test) spacecraft successfully crashed on Dimorphos, the secondary component of the binary (65803) Didymos system. Following the impact, a…
ALMA Observations of the DART Impact: Characterizing the Ejecta at Sub-Millimeter Wavelengths
Nathan X. Roth, Stefanie N. Milam, Anthony J. Remijan +12
We report observations of the Didymos-Dimorphos binary asteroid system using the Atacama Large Millimeter/Submillimeter Array (ALMA) and the Atacama Compact Array (ACA) in support…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
