Kuiper Belt Object Sizes and Distances from Occultation Observations [PDF]

open access: yesAstrophys.J. 589 (2003) L97-L100, 2003
There are several observational campaigns under way to detect kilometer size foreground Kuiper Belt Objects (KBOs) through their occultation of background stars. The interpretation of an occultation light curve, unfortunately, is affected by a geometric degeneracy such that one is unable to determine the KBO size independent of its distance.

Asteroid astrometry by stellar occultations: Accuracy of the existing sample from orbital fitting [PDF]

open access: yes, 2022
Context: Stellar occultations, greatly enhanced by the publication of the Gaia data releases, permit not only the determination of asteroid size and shape, but also the retrieval of additional, accurate astrometry, with a possible relevant impact on the study of dynamical properties.

Trials Evaluating Solarization and Tarping for Improved Stale Seedbed Preparation in the Northeast USA

open access: yesOrganic Farming, 2019
Stale seedbeds are commonly used by organic vegetable farmers to reduce in-season weed density. The primary purpose of this study was to evaluate the efficacy of soil solarization (clear plastic) with subsequent flaming for stale seedbed preparation.
