When:  Friday, July 17th at 3:00 pm (Central DST)

Where:  online only – see details below


About the topic: Classifying asteroids by color and spectral features is important for understanding their compositions, linkages to meteorite types, and formation and evolution of the Solar System in general.  Large data collection efforts such as the Sloan Digital Sky Survey (SDSS) have allowed for more comprehensive studies of the asteroid population.  However, the repeatability and therefore reliability of such observations comes into question, especially as Szabo et al. (2004) and Carvano et al. (2010) reported sizable fractions of asteroids observed by SDSS exhibiting taxonomic variability.  This research studied two near-Earth asteroids (NEAs) with just one observation each by SDSS: 2059 Baboquivari and 96744 (1999 OW3).  Observations using the 1 m Yale/SMARTS telescope at Cerro-Tololo International Observatory (CTIO) were conducted in order to investigate whether g, r, i, and z spectrophotometry was consistent with spectrophotometry by SDSS.

Advisor:  Dr. Ron Fevig
