We present coordinated near-infrared K-band interferometric and optical spectroscopic observations of the M 1.5 giant α Cet (Menkar) obtained with the instruments VINCI and UVES at the Paranal Observatory. Spherically symmetric PHOENIX stellar model atmospheres are constrained by comparison to our interferometric and spectroscopic data, and high-precision fundamental parameters of Menkar are obtained. Methods. Our high-precision VLTI/VINCI observations in the first and second lobes of the visibility function directly probe the model-predicted strength of the limb darkening effect in the K-band and the stellar angular diameter. The high spectral resolution of UVES of R = 80 000–110 000 allows us to confront in detail observed and model-predicted profiles of atomic lines and molecular bands. Results. We show that our derived PHOENIX model atmosphere for Menkar is consistent with both the measured strength of the limb- darkening in the near-infrared K-band and the profiles of spectral bands around selected atomic lines and TiO bandheads from 370 nm to 1000 nm.

Allende Prieto, S. Redfield, and D. L. Lambert McDonald Observatory and Department of Astronomy, University of Texas at Austin, RLM 15.306 Austin, TX, 78712-1083, USA e-mail: [ivan;callende;sredfield;dll]@astro.as.utexas.edu Received 22 May 2006 / Accepted 21 August 2006 ABSTRACT The atmospheric parameters and iron abundance of the Sloan Digital Sky Survey (SDSS) spectrophotometric standard star BD +17 4708 are critically examined using up-to-date Kurucz model atmospheres, LTE line formation calculations, and reli- able atomic data. We find Teff = 6141 ± 50 K, log g = 3.87 ± 0.08, and [Fe/H] = −1.74 ± 0.09. The line-of-sight interstellar reddening, bolometric flux, limb-darkened angular diameter, stellar mass, and the abundances of Mg, Si, and Ca are also obtained: −9 −2 −1 E(B−V) = 0.010 ± 0.003, fbol = (4.89±0.10) × 10 erg cm s , θ = 0.1016 ± 0.0023 mas, M = 0.91 ± 0.06 M,[Mg/Fe] = 0.40 ± 0.10, [Si/Fe] = 0.35 ± 0.11, [Ca/Fe] = 0.36 ± 0.11. This star is a unique example of a moderately metal-poor star for which the effective temperature (Teff) can be accurately constrained from the observed spectral energy distribution (corrected for reddening). Such analysis leads to a value that is higher than most spectroscopic results previously reported in the literature (∼5950 K).

  • Cerberus.Pdf
    (lP,IIP,U' By Gaynor Borade Greek mythology comprises a huge pantheon, extensive use of anthropomorphism and mythical creatures that ore symbotic. Cerberus, the three headed dog was believed to be the guardian of the reotm of death, or Hades. Cerberus, it was believed, prevented those who crossed the river of death, Styx, from escoping. River Styx was supposed to be the boundory belween the Underworld and Earth. Greek mythology propounded thot Hodes or ihe Underworld wos encircled nine times by River Styx and thot the rivers Phlegethon, Cocytus, Lelhe, Eridanos and Acheron converged with Styx on the 'Great Marsh'. Cerberus guorded the Great Marsh. Importance of Styx in Greek Mythotogy: Hades ond Persephone were believed to be the mortol portals in the Underworld. This reotm wos atso home to Phlegyos or guardian of the River Phlegethon, Charon or Kharon, the ferrymon, ond the living waters of Styx. Styx wos believed to have miraculous powers thot could make o person immorfol, resulting in the grove need for it to be guorded. This reolm relates to the concept of 'hel[' in Christianity and the 'Paradise losf', in the Iiterary genius of 'The Divine Comedy'. In Greek myihology, the ferrymon Charon was in charge of iransporting souls across the Styx, into the Underworld. Here, it was believed thaf the sullen were drowned in Sfyx's muddy waters. Cerberus:The Guardion Cerberus, the mythical guordian of River Styx has been immorlalized through many works of ancient Greek liferoture, ort ond orchitecture. Cerberus is easity recognizabte among the other members of the pontheon due to his three heads.

José Cristino 77, 20921-400 São Cristovão, Rio de Janeiro, Brazil Received 28 December 2011 / Accepted 22 April 2012 ABSTRACT Aims. We report the derivation of abundances of C, Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, Ce, Nd, and Sm in a sample of 25 solar-type stars of the solar neighbourhood, correlating the abundances with the stellar ages, kinematics, and orbital parameters. Methods. The spectroscopic analysis, based on data of high resolution and high signal-to-noise ratio, was differential to the Sun and applied to atomic line equivalent widths supplemented by the spectral synthesis of C and C2 features. We also performed a statistical study by using the method of tree clustering analysis, searching for groups of stars sharing similar elemental abundance patterns. We derived the stellar parameters from various criteria, with average errors of 30 K, 0.13 dex, and 0.05 dex, respectively, for Teff , log g,and[Fe/H].

  • The Gravity of Hades
    VOL. 75, NO. 5, DECEMBER2002 335 The Gravityof Hades ANDREWJ. SIMOSON King College Bristol, TN 37620 [email protected] Imaginebeing beamedinto a chamberdeep withinthe Earth,such as depictedin the JulesVerne cavern of FIGURE1. Is the accelerationdue to gravitystronger or weaker in the chamberthan at the surfaceof the Earth?If the readeris hesitantin answering immediately,here's how LeonardEuler answered the questionin 1760 [3, volume I, LetterL, p. 182]: We are certain ... that gravity ... acts with the greatest force at the surface of the earth, and is diminished in proportion as it removesfrom thence, whether by penetrating towards the centre or rising above the surface of the globe. Figure1 Frontispiecefor Verne's1871 publication of Journeyto the Centerof the Earth, 100 miles below Iceland To answer this question, we consider various models of the Earth's structure that have been proposed over the years. We show that ? for homogeneouslydense planets-Euler's implicitmodel-gravity weakenswith descentfrom the surface; ? for a planetpossessing a homogeneousmantle that is less than 2/3 as dense as its core, a local minimumfor gravityintensity exists withina sufficientlythick mantle; ? for our own Earth,having a solid innercore, a less dense liquidouter core, and an extensiveeven less densemantle, gravity intensifies with descentfrom -9.8 m/s2 at the surfaceto an extremeof -10.8 m/s2 wherethe mantlemeets the core. We also give a conditioninvolving only surfacedensity and mean density that deter- mineswhether gravity increases or decreaseswith depthfrom the surfaceof a planet; and we concludewith an analysisof a body falling througha classicallyenvisioned hole through the Earth. 336 MATHEMATICSMAGAZINE Some preliminary classical mechanics To find the gravitational acceleration induced by the Earth on a particularpoint P, we follow Newton and first find the gravitational acceleration induced by each point of the Earth on P, and then take the aggregate of these accelerations as the total acceleration induced by the Earth.
