Measuring the Abundance of sub-kilometer sized Kuiper Belt Objects using Stellar Occultations
Hilke E. Schlichting, Eran O. Ofek, Re'em Sari +6
We present here the analysis of about 19,500 new star hours of low ecliptic latitude observations (|b| < 20 deg) obtained by the Hubble Space Telescope's FGS over a time span of mo…
The PTF Orion Project: a Possible Planet Transiting a T-Tauri Star
Julian C. van Eyken, David R. Ciardi, Kaspar von Braun +35
We report observations of a possible young transiting planet orbiting a previously known weak-lined T-Tauri star in the 7-10 Myr old Orion-OB1a/25-Ori region. The candidate was fou…
SDSS Observations of Kuiper Belt Objects: Colors and Variability
Eran O. Ofek
Colors of Trans Neptunian Objects (TNOs) are used to study the evolutionary processes of bodies in the outskirts of the Solar System, and to test theories regarding their origin. H…
Asteroid rotation periods from the Palomar Transient Factory survey
D. Polishook, E. O. Ofek, A. Waszczak +17
The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient and variable sky in a wide variety of cadences. We use PTF observations of fields that we…
MOA-2011-BLG-293Lb: A test of pure survey microlensing planet detections
J. C. Yee, Y. Shvartzvald, A. Gal-Yam +10
Because of the development of large-format, wide-field cameras, microlensing surveys are now able to monitor millions of stars with sufficient cadence to detect planets. These new…
