Observations of a successive stellar occultation by Charon and graze by Pluto in 2011
Introduction: Since the late 1980s, stellar occultations have provided snapshots of the Pluto system and specifically of Pluto’s atmospheric evolution. The lower atmosphere, below roughly half-light level in an occultation light curve, has changed distinctly over time (e.g. [1, 2]). Theorized explanations for the lower atmospheric structure include a steep thermal gradient and/or extinction, th...
متن کاملOn an impact origin of Pluto-Charon
Walnut Street, Suite 400, Boulder, CO 80302 [email protected], Earth Sciences Department, University of California; Santa Cruz, CA 95064. Introduction: The Pluto-Charon system shares key commonalities with the Earth-Moon system, e.g., its large satellite-to-planet mass ratio, high system angular momentum and a potentially reduced satellite density relative to that of the planet. In both ca...
متن کاملCharon tectonics
New Horizons images of Pluto's companion Charon show a variety of terrains that display extensional tectonic features, with relief surprising for this relatively small world. These features suggest a global extensional areal strain of order 1% early in Charon's history. Such extension is consistent with the presence of an ancient global ocean, now frozen.

This workshop will present the importance of creative work in the clinical practice of the clinician or bioethicist. First I will present some of the narratological theories of close reading and aesthetic theories of creative writing. We will join in close reading of one or two clinical texts and literary texts, creative writing in the context of those texts, and then reading to one another wha...
متن کاملOccultation and Microlensing
Occultation and microlensing are different limits of the same phenomena of one body passing in front of another body. We derive a general exact analytic expression which describes both microlensing and occultation in the case of spherical bodies with a source of uniform brightness and a non-relativistic foreground body. We also compute numerically the case of a source with quadratic limb-darken...
