Spectral Effects of Shock Darkening on Ordinary Chondrite and Howardite, Eucrite, and Diogenite meteorites
Juan A. Sanchez, Vishnu Reddy, Lucille Le Corre +2
Impacts are the most ubiquitous processes on planetary bodies in our solar system. During these impact events, shock waves can deposit enough energy to produce shock-induced darken…
The population of small near-Earth objects: composition, source regions and rotational properties
Juan A. Sanchez, Vishnu Reddy, Audrey Thirouin +7
The study of small (300 m) near-Earth objects (NEOs) is important because they are more closely related than larger objects to the precursors of meteorites that fall on Earth. C…
Grain Size Effects on UV-MIR (0.2-14 micron) Spectra of Carbonaceous Chondrite Groups
David C. Cantillo, Vishnu Reddy, Adam Battle +7
Carbonaceous chondrites are among the most important meteorite types and have played a vital role in deciphering the origin and evolution of our solar system. They have been linked…

Mineralogical Characterization and Phase Angle Study of Two Binary Near-Earth Asteroids, Potential Targets for NASA's Janus Mission
Lucille Le Corre, Juan A. Sanchez, Vishnu Reddy +5
Ground-based characterization of spacecraft targets prior to mission operations is critical to properly plan and execute measurements. Understanding surface properties, like minera…
Physical Characterization of Near-Earth Asteroid (52768) 1998 OR2: Evidence of Shock 1 Darkening/Impact Melt
Adam Battle, Vishnu Reddy, Juan A. Sanchez +3
We conducted photometric and spectroscopic characterization of near-Earth asteroid (52768) 1998 OR2 during a close approach to the Earth in April of 2020. Our photometric measureme…
Near-Infrared Spectroscopy Of The Nucleus Of Low-Activity Comet P/2016 BA During Its 2016 Close Approach
Theodore Kareta, Vishnu Reddy, Juan A. Sanchez +1
The Near-Earth Comet P/2016 BA (PanSTARRS) is a slow-rotatating nearly-dormant object, a likely dynamical twin of 252P/LINEAR, and was recently shown to have a mid-infrared…
Lunar-like silicate material forms the Earth quasisatellite (469219) 2016 HO3 Kamo`oalewa
Benjamin N. L. Sharkey, Vishnu Reddy, Renu Malhotra +7
Little is known about Earth quasi-satellites, a class of near-Earth small solar system bodies that orbit the sun but remain close to the Earth, because they are faint and difficult…
Physical Characterization of Metal-rich Near-Earth Asteroids 6178 (1986 DA) and 2016 ED85
Juan A. Sanchez, Vishnu Reddy, William F. Bottke +5
Metal-rich near-Earth asteroids (NEAs) represent a small fraction of the NEA population that is mostly dominated by S- and C-type asteroids. Because of this, their identification a…
Investigating the Relationship between (3200) Phaethon and (155140) 2005 UD through Telescopic and Laboratory Studies
Theodore Kareta, Vishnu Reddy, Neil Pearson +2
The relationship between the Near-Earth Objects (3200) Phaethon and (155140) 2005 UD is unclear. While both are parents to Meteor Showers, (the Geminids and Daytime Sextantids, res…
Complex Water Ice Mixtures on NII Nereid: Constraints from NIR Reflectance
Benjamin N. L. Sharkey, Vishnu Reddy, Juan A. Sanchez +2
Nereid, Neptune's third largest satellite, lies in an irregular orbit and is the only outer satellite in the system (apart from Triton) that can be spectroscopically characterized…
