Title: Ambiguous Taxonomic Asteroid Research

About the topic:  The Sloan Digital Sky Survey (SDSS) serendipitously observed asteroids during their North Galactic Cap survey. SDSS utilizing a 2.5m telescope observed an asteroid population much smaller than ever studied before. Over half of the asteroids observed more than once have significant color changes between observations. These variations imply that the smaller main-belt asteroid population has heterogeneous surfaces. However, some asteroid researchers have called SDSS’s results into question. Therefore, this research using a multi-facet approach will attempt to understand the source of the asteroid color variations to determine if the changes are real or if there is an unknown source of error in the SDSS data.

About the presenter:   Tyler Linder received a B.S. in Physics from Eastern Illinois University in 2012 and an M.S. in Space Studies from the University of North Dakota in 2017. Mr. Linder is an asteroid astronomer at the Astronomical Research Institute. He conducts astrometric observations on Near-Earth Asteroids (NEAs) using telescopes located at Cerro Tololo Inter-American Observatory (CTIO) in Chile.

Faculty advisor: Dr. Ron Fevig
