  • In-System'' Fission-Events: an Insight Into Puzzles of Exoplanets and Stars?
    universe Review “In-System” Fission-Events: An Insight into Puzzles of Exoplanets and Stars? Elizabeth P. Tito 1,* and Vadim I. Pavlov 2,* 1 Scientific Advisory Group, Pasadena, CA 91125, USA 2 Faculté des Sciences et Technologies, Université de Lille, F-59000 Lille, France * Correspondence: [email protected] (E.P.T.); [email protected] (V.I.P.) Abstract: In expansion of our recent proposal that the solar system’s evolution occurred in two stages—during the first stage, the gaseous giants formed (via disk instability), and, during the second stage (caused by an encounter with a particular stellar-object leading to “in-system” fission- driven nucleogenesis), the terrestrial planets formed (via accretion)—we emphasize here that the mechanism of formation of such stellar-objects is generally universal and therefore encounters of such objects with stellar-systems may have occurred elsewhere across galaxies. If so, their aftereffects may perhaps be observed as puzzling features in the spectra of individual stars (such as idiosyncratic chemical enrichments) and/or in the structures of exoplanetary systems (such as unusually high planet densities or short orbital periods). This paper reviews and reinterprets astronomical data within the “fission-events framework”. Classification of stellar systems as “pristine” or “impacted” is offered.

Kibler Institut de Physique Nucl´eaire de Lyon IN2P3-CNRS et Universit´eClaude Bernard 43 Bd du 11 Novembre 1918, F-69622 Villeurbanne Cedex, France This paper is concerned with the application of the group SO(4, 2)⊗SU(2) to the periodic table of chemical elements. It is shown how the Madelung rule of the atomic shell model can be used for setting up a periodic table that can be further rationalized via the group SO(4, 2)⊗SU(2) and some of its subgroups. Qualitative results are obtained from the table and the general lines of a programme for a quantitative approach to the properties of chemical elements are developed on the basis of the group SO(4, 2)⊗SU(2).

  • Iron-Group Opacities in the Envelopes of Massive Stars

We have first investigated the origins of the differences noticed between OP and OPAL iron and nickel opacity calculations (up to a factor 2), a fact which complicates the interpretation. To accomplish this task, new well- qualified calculations (SCO-RCG, HULLAC and ATOMIC) have been performed and compared to values of these tables, and most of the differences are now well understood. Next, we have exploited a dedicated experiment on chromium, iron and nickel, conducted at the LULI 2000 facilities. We found that, in the case of iron, detailed calculations (OP, ATOMIC and HULLAC) show good agreement, contrary to all of the non-detailed calculations. However, in the case of nickel, OP calculations show large discrepancies with the experiments but also with other codes. Thus, the opacity tables need to be revised in the thermodynamical conditions corresponding to the peak of the iron group. Consequently we study the evolution of this iron peak with changes in stellar mass, age, and metallicity to determine the relevant region where these tables should be revised.

They decompose cold water; they deteriorate in air, forming hydroxides. (1) Lithium. This is the lightest (specific gravity 0.54) and hardest of the group. It is kept in mineral oil or inert gases. Lithium helps to improve the qualities of metals, and is used in various alloys (e.g., anti-friction alloys). Because of its great affinity for other elements, it is also used, inter alia, to obtain other metals in the pure state. (2) Sodium. A solid (specific gravity 0.97) with a metallic lustre, readily tarnishing after cutting. It is preserved in mineral oil or in airtight welded tins. Sodium is obtained by electrolysing molten sodium chloride or sodium hydroxide. It is used in the manufacture of sodium peroxide (“ dioxide ”), sodium cyanide, sodamide, etc., the indigo industry, the manufacture of explosives (chemical primers and fuses), the polymerisation of butadiene, anti-friction alloys, or titanium or zirconium metallurgy. The heading excludes sodium amalgam (heading 28.53). (3) Potassium. A silvery-white metal (specific gravity 0.85), which can be cut with an ordinary knife. It is preserved in mineral oil or in sealed ampoules. Potassium is used for the preparation of certain photoelectric cells, and in anti-friction alloys.

  • Melting Points of the Iron Group Elements by a New Radiation Method
    MELTING POINTS OF THE IRON GROUP ELEMENTS BY A NEW RADIATION METHOD. By Geo. K. Burgess. Recently^ Dr. Waidner and the author suggested two radiation methods for the determination of high melting points of substances in minute quantities. The first depends on the total radiation from a surface as measured in terms of some instrument making use of the Stefan-Bolzmann law. The second method is based on the meas- urement of the intensit}^ of a particular monochromatic radiation from platinum or other substance; that is, it makes use of an instru- ment based on Wien's equation.^ Some preliminary measurements made at that time by the second method on the metals of the iron group showed it to possess consid- erable accuracy and to be particularly applicable to the easily oxi- dized elements if the melts were obtained in an atmosphere of pure hydrogen. It was also demonstrated that a compound of one of the refractory elements, which could be reduced to the metal by hydro- gen, might serve as material for determining the melting point of the pure metal. The present paper is an account of the application of this second method to the determination of the melting points in hydrogen of the members of the iron group, using, for the measurement of tem- perature a Holborn-Kurlbaum optical pyrometer, and the data on the monochromatic radiation from platinum published in this Bulletin.' ^Waidner and Burgess: On the Determination of Melting Points by Radiation Method, Phys.

D. Hoyer1, T. Rauch1, K. Werner1, and J.W. Kruk2 1 Institute for Astronomy and Astrophysics, Kepler Center for Astro and Particle Physics, Eberhard Karls University, Sand 1, 72076 Tübingen, Germany e-mail: [email protected] 2 NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA Received 2 December 2017 / Accepted 3 January 2018 ABSTRACT The metal abundances in the atmospheres of hot white dwarfs (WDs) entering the cooling sequence are determined by the preceding Asymptotic Giant Branch (AGB) evolutionary phase and, subsequently, by the onset of gravitational settling and radiative levitation. In this paper, we investigate three hot He-rich WDs, which are believed to result from a late He-shell flash. During such a flash, the He-rich intershell matter is dredged up and dominates the surface chemistry. Hence, in contrast to the usual H-rich WDs, their spectra allow direct access to s-process element abundances in the intershell that were synthesized during the AGB stage. In order to look for trans-iron group elements (atomic number Z > 29), we performed a non-local thermodynamic equilibrium model atmosphere analysis of new ultraviolet spectra taken with the Cosmic Origins Spectrograph aboard the Hubble Space Telescope. One of our program stars is of PG 1159 spectral type; this star, PG 1707+427, has effective temperature Teff = 85 000 K, and surface gravity log g = 7:5.
