Dynamic Trajectory Analysis of Meteoroids Showing Minimal Deceleration
Thomas Stevenson, Ellie Sansom, Hadrien Devillepoix +8
Meteoroids decelerate and ablate as they descend through the atmosphere, however a portion of instrumentally observed meteors show little measurable deceleration and remain poorly…
The Non-Principal-Axis Rotation and Convex Shape Model of Earth Quasi-Satellite and the Target of China's Tianwen-2 Mission (469219) Kamo`oalewa
Xiaoyu Sun, Zhijun Song, Hanjie Tan +8
(469219) Kamo`oalewa is the most stable Earth quasi-satellite and the target of China's Tianwen-2 asteroid sample return mission. Due to its small size, fast rotation, and the limi…
A Machine Learning Approach to Meteor Classification
Samantha Hemmelgarn, Nicholas Moskovitz, Denis Vida
We use machine learning to develop a framework for classifying meteoroids based on 13 directly observed parameters from the Global Meteor Network. This method adds depth to the $K_…
NEO Colors from The Mission Accessible Near-Earth Object Survey (MANOS)
Nicholas Moskovitz, Theodore Kareta, Samantha Hemmelgarn +13
We present spectro-photometric griz colors for 189 near-Earth objects (NEOs) collected by the Mission Accessible Near-Earth Object Survey (MANOS). Data acquisition involved non-sim…
How Meteor Showers Can Guide the Search for Long Period Comets
Samantha Hemmelgarn, Nicholas Moskovitz, Stuart Pilorz +1
With orbital periods longer than 200 years, most long-period comets (LPCs) remain undiscovered until they are in-bound towards perihelion. The comets that pass close to Earth's orb…
