A Wunda-Full World? Carbon Dioxide Ice Deposits on Umbriel and Other Uranian Moons
Icarus 290 (2017) 1–13 Contents lists available at ScienceDirect Icarus journal homepage: www.elsevier.com/locate/icarus A Wunda-full world? Carbon dioxide ice deposits on Umbriel and other Uranian moons ∗ Michael M. Sori , Jonathan Bapst, Ali M. Bramson, Shane Byrne, Margaret E. Landis Lunar and Planetary Laboratory, University of Arizona, Tucson, AZ 85721, USA a r t i c l e i n f o a b s t r a c t Article history: Carbon dioxide has been detected on the trailing hemispheres of several Uranian satellites, but the exact Received 22 June 2016 nature and distribution of the molecules remain unknown. One such satellite, Umbriel, has a prominent Revised 28 January 2017 high albedo annulus-shaped feature within the 131-km-diameter impact crater Wunda. We hypothesize Accepted 28 February 2017 that this feature is a solid deposit of CO ice. We combine thermal and ballistic transport modeling to Available online 2 March 2017 2 study the evolution of CO 2 molecules on the surface of Umbriel, a high-obliquity ( ∼98 °) body. Consid- ering processes such as sublimation and Jeans escape, we find that CO 2 ice migrates to low latitudes on geologically short (100s–1000 s of years) timescales. Crater morphology and location create a local cold trap inside Wunda, and the slopes of crater walls and a central peak explain the deposit’s annular shape. The high albedo and thermal inertia of CO 2 ice relative to regolith allows deposits 15-m-thick or greater to be stable over the age of the solar system. -

ABSTRACT The Water Vapor and Dust Plumes of Enceladus by Yaxue Dong Enceladus is the most active moon of Saturn. Its south polar plume, composed mostly of water vapor and ice grains, is one of the groundbreaking discoveries made by the Cassini spacecraft. During Cassini’s E2, E3, E5 and E7 encounters with Enceladus, the Ion and Neutral Mass Spectrometer (INMS) measured high neutral water vapor densities up to ~109 cm-3 (Waite et al., 2006; Teolis et al., 2010; Dong et al., 2011). We have constructed a physical model for the expected water vapor density in the plumes, based on supersonic radial outflow from one or more of the surface vents. We apply this model to possible surface sources of water vapor associated with the dust jets (Spitale and Porco, 2007; Hansen et al., 2008). Our model fits well with the E3, E5, and E7 INMS data. The fit is optimized by the 28 outflow velocity of ~ 550 – 750 m/s and the total source rate of ~ 1.5 − 3.5×10 H2O molecules/s (~ 450 – 1050 kg/s). The dust (ice grain) plumes of Enceladus have been observed by multiple Cassini instruments. We propose a composite ice grain size distribution covering a continuous size range from nanometer to micrometers, by combining the CAPS (Cassini Plasma Spectrometer), CDA (Cosmic Dust Analyzer), and RPWS (Radio and Plasma Wave Science) data (Hill et al., 2012; Kempf et al., 2008; Ye et al., 2012, 2013). We also study the grain charging process using the RPWS-LP (Langmuir Probe) data (Morooka et al., 2011). -
“Savage and Deformed”: Stigma As Drama in the Tempest Jeffrey R
“Savage and Deformed”: Stigma as Drama in The Tempest Jeffrey R. Wilson The dramatis personae of The Tempest casts Caliban as “asavageand deformed slave.”1 Since the mid-twentieth century, critics have scrutinized Caliban’s status as a “slave,” developing a riveting post-colonial reading of the play, but I want to address the pairing of “savage and deformed.”2 If not Shakespeare’s own mixture of moral and corporeal abominations, “savage and deformed” is the first editorial comment on Caliban, the “and” here Stigmatized as such, Caliban’s body never comes to us .”ס“ working as an uninterpreted. It is always already laden with meaning. But what, if we try to strip away meaning from fact, does Caliban actually look like? The ambiguous and therefore amorphous nature of Caliban’s deformity has been a perennial problem in both dramaturgical and critical studies of The Tempest at least since George Steevens’s edition of the play (1793), acutely since Alden and Virginia Vaughan’s Shakespeare’s Caliban: A Cultural His- tory (1993), and enduringly in recent readings by Paul Franssen, Julia Lup- ton, and Mark Burnett.3 Of all the “deformed” images that actors, artists, and critics have assigned to Caliban, four stand out as the most popular: the devil, the monster, the humanoid, and the racial other. First, thanks to Prospero’s yarn of a “demi-devil” (5.1.272) or a “born devil” (4.1.188) that was “got by the devil himself” (1.2.319), early critics like John Dryden and Joseph War- ton envisioned a demonic Caliban.4 In a second set of images, the reverbera- tions of “monster” in The Tempest have led writers and artists to envision Caliban as one of three prodigies: an earth creature, a fish-like thing, or an animal-headed man. -

(Mauk et al., (Saturn, Chapter 11) state: “while it is true that Saturn’s magnetosphere is intermediate between those of Earth and Jupiter in terms of size (whether measured by RP; RPP, or RMP), it is not intermediate in any meaningful dynamical sense. It is clearly rotationally driven like Jupiter’s, not solar-wind–driven like Earth’s.” Margaret Kivelson- Dynamics - MoP 6/27/2013 2011 – Boston University 2 This Vasyliunas (1983) diagram is a necessary element of any discussion of the magnetospheres of gas giants! It captures some critical features implicitly or explicitly: A significant source of heavy plasma deep within the magnetopause (Io, Enceladus) is spun up to some fraction of corotation speed by field-aligned currents coupling magnetosphere and ionosphere. Rotation dominates the dynamics – drives plasmoid releases down the tail. Solar wind shapes the boundaries but does not dominate the dynamics.

10 Ecce Parentes
“Ch 10” YON-II/ Ramos 1 10 ECCE PARENTES Walking on water was an angel. He was Uriel, the Archangel of Wisdom, one of Earth’s overseers and a liaison between Heaven and Earth. He was tall, imposing, and two ranks above Setebos in the Watcher chain of command. Thanks to having been Miranda’s protégé once upon a time, Cora knew who Uriel was, and none of those things she gave a damn. From the shoreline of the inner cave, she stood her ground. “Did you come here,” she said, “just to say that?” “Cora --” Setebos began, anxiously. “No,” Uriel said, “although I was surprised by your – er – present condition, young woman. Perhaps I spoke out of turn.” “PERHAPS?” “Cora, please --” “Setebos,” Uriel said. “Sir?” The archangel shook his head. “I think we’re beyond formalities now, Setebos. I came here to bring a message to you, a fallen Watcher who cared enough about good and evil to put yourself in solitary. However, I see that you still have that Celestial Engineer temptation to ‘fix’ humans and thus create unnecessary complications for yourself --” Uriel nodded towards Cora, “-- and others.” Cora clenched her jaw but remained silent. “I failed,” Setebos said. “That’s why you’re here, right? Despite my precautions, I meddled with the affairs of humans again…” He trailed off. “You came to tell me that the Reboot will happen.” “Yes,” Uriel confirmed. “However, the Reboot isn’t because of you. As this young woman can attest, Earth has become too corrupted to remain as is. It needs a clean slate to restart anew.” “But what about her and --” “I need to walk,” Cora announced, angry that they were talking about her in the third person, as if she weren’t there. -

After the work of Gladman et al. (1998, Nature, 392, 897), it is now assessed that many irregular satellites are orbiting around Uranus. Aims. Despite many studies performed in past years, very little is know about the light-curves of these objects and inconsistencies are present between colours derived by different authors. This situation motivated our effort to improve both the knowledge of colours and light curves. Methods. We present and discuss, the time series observations of Sycorax, Prospero, Stephano, Setebos, and Trinculo, five faint, irregular satellites of Uranus, which were carried out at VLT, ESO Paranal (Chile) on the nights between 29 and 30 July, 2005 and 25 and 30 November, 2005. -

According to the role-model hypothesis, the gender match between scientist and influencer is paramount (for example, women scientists would disproportionately often mention their mothers as career influencers)," scientists writing in the journal Social Studies of Science report (see also ). "According to the opportunity-structure hypothesis, the parent's educational level predicts his/her probability of being mentioned as a career influencer (that ism parents with higher educational levels would be more likely to be named). The examination of a sample of American scientists who had received prestigious postdoctoral fellowships resulted in rejecting the role-model hypothesis and corroborating the opportunity-structure hypothesis. -

Here each character is shown to represent one of the archetypes which Jung described in his book Archetypes ~ the Collective Unconscious. In giving the play a psychological interpretation, the action must be seen to occur inside Prospera's own unconscious mind. He is experiencing a psychic transformation or what Jung called the individuation process, where a person becomes "a separate, indivisible unity or 2 whole" and where the conscious and unconscious are united. -

Möglichst viele solcher Darstel lungen und Vorkommen sollen hier zwar genannt werden (obschon dem Verfasser auch nicht annähernd alle bekannt wurden), wichtiger war aber ein Leitgedanke, der sowohl etwas vom Wesen des Gottes selbst spüren ließ als auch von der Eigenart derer, die ihn dargestellt oder in ihren Werken haben vorkommen lassen, und dieser Leitgedanke war etwa dieser: § 2 Renaissance, Wiedergeburt der Antike - sie geschah mehrfachI), im neunten, im zwölften und besonders erregend im 15.

Göttergestalten in der Antike bei aller Menschenähnlichkeit nicht nur immer eine gewaltige Macht behielten, denen die späteren Darstellungen zu entsprechen hatten, sondern daß in ihnen eine Spannung von Gegensätzlichem (Henrichs, Loss 235 ff.; Versne1133) herrschte, welche die Späte• ren nur allzu leicht durch Vereinseitigung oder dadurch ins Harmlose abgleiten ließen, daß sie z.
