The Shape of Nereid's Phase Function Changed From 1998 To 1999 and 2000
Bradley E. Schaefer, Suzanne W. Tourtellotte
We present well-sampled light curves of Nereid for 1999 and 2000 which show symmetric shapes centered on opposition as is characteristic of a large opposition surge. Surprisingly,…

Explaining the Gamma Ray Burst Lag/Luminosity and Variability/Luminosity Relations
Bradley E. Schaefer
Two different luminosity indicators have been recently proposed for Gamma Ray Bursts that use the lag between light curve peaks with hard and soft photons as well as the variabilit…
