The TAOS Project Stellar Variability I. Detection of Low-Amplitude delta Scuti Stars

D. -W. Kim, P. Protopapas, C. Alcock +22

We analyzed data accumulated during 2005 and 2006 by the Taiwan-American Occultation Survey (TAOS) in order to detect short-period variable stars (periods of <~ 1 hour) such as del…

Searching for sub-kilometer TNOs using Pan-STARRS video mode lightcurves: Preliminary study and evaluation using engineering data

J. -H. Wang, P. Protopapas, W. -P. Chen +6

We present a pre-survey study of using Pan-STARRS high sampling rate video mode guide star images to search for TNOs. With suitable selection of the guide stars within the Pan-STAR…

Upper Limits on the Number of Small Bodies in Sedna-Like Orbits by the TAOS Project

J. -H. Wang, M. J. Lehner, Z. -W. Zhang +21

We present the results of a search for occultation events by objects at distances between 100 and 1000 AU in lightcurves from the Taiwanese-American Occultation Survey (TAOS). We s…

A Bayesian approach to the analysis of time symmetry in light curves: Reconsidering Scorpius X-1 occultations

Alexander W. Blocker, Pavlos Protopapas, Charles R. Alcock

We present a new approach to the analysis of time symmetry in light curves, such as those in the x-ray at the center of the Scorpius X-1 occultation debate. Our method uses a new p…

A Search for Occultations of Bright Stars by Small Kuiper Belt Objects using Megacam on the MMT

Federica B. Bianco, Pavlos Protopapas, Brian A. McLeod +3

We conducted a search for occultations of bright stars by Kuiper Belt Objects (KBOs) to estimate the density of sub-km KBOs in the sky. We report here the first results of this occ…

Reverberation in the UV-Optical Continuum Brightness Fluctuations of MACHO Quasar 13.5962.237

Rudolph E. Schild, Justin Lovegrove, Pavlos Protopapas

We examine the nature of brightness fluctuations in the UV-Optical spectral region of an ordinary quasar with 881 optical brightness measurements made during the epoch 1993 - 1999.…
