Um dos objetivos de se realizar esse evento nessa cidade foi prestigiar um grupo de pesquisa em Astronomia que se estabeleceu na UFSC; também, foi uma forma de reconhecer a visão dessa instituição em abrir uma linha de pesquisa em Astronomia. Certamente, é uma decisão mais do que acertada investir na pesquisa em Astronomia, que, por seu caráter multidisciplinar, fomenta tanto a pesquisa básica quanto a tecnológica. A Astronomia ainda precisa crescer muito no Brasil, principalmente com a implementação de grupos de pesquisa no maior número possível de universidades públicas e privadas, de forma a proporcionar que a ciência brasileira seja cada mais forte e possa contribuir para a melhoria da educação de nossos jovens e promover o desenvolvimento global de nossa sociedade. Assim, a realização de nossa reunião prestigiando a UFSC é um marco emblemático para a Astronomia Brasileira. Esperamos que num futuro próximo haja reuniões da SAB em localidades que hoje sequer cogitamos! Com essa reunião em Florianópolis, temos a certeza de que está em marcha um crescimento da Astronomia no Brasil.

Tremaine • 1993 by Craig Skinner and Kim Tremaine International Association for Obsidian Studies Department of Anthropology San Jose State University San Jose, CA 95192-0113 International Association for Obsidian Studies Occasional Paper No. 1 1993 Magmas cooled to freezing temperature and crystallized to a solid have to lose heat of crystallization. A glass, since it never crystallizes to form a solid, never changes phase and never has to lose heat of crystallization. Obsidian, supercooled below the crystallization point, remained a liquid. Glasses form when some physical property of a lava restricts ion mobility enough to prevent them from binding together into an ordered crystalline pattern. Aa the viscosity ofthe lava increases, fewer particles arrive at positions of order until no particle arrangement occurs before solidification. In a glaas, the ions must remain randomly arranged; therefore, a magma forming a glass must be extremely viscous yet fluid enough to reach the surface. 1he modem rational explanation for obsidian petrogenesis (Bakken, 1977:88) Some people called a time at the flat named Tok'. They were going to hunt deer. They set snares on the runway at Blood Gap. Adder bad real obsidian. The others made their arrows out of just anything. They did not know about obsidian. When deer were caught in snares, Adder shot and ran as fast as he could to the deer, pulled out the obsidian and hid it in his quiver.

It is shown that branches that correspond to Z-mode and ordinary waves approach each other when the magnetic field increases and become practically indistinguishable in a broad region of frequencies at all angles between the wave vector and the magnetic field. At angles between the wave vector and the magnetic field close to 90◦, a wave branch with an anomalous dispersion may occur. On the basis of the obtained results we suggest a new interpretation of such events in solar and stellar radio emission as broadband pulsations and spikes.

  • Tures in the Chromosphere, Whereas at Meter Wavelengths It Is of the Order of 1.5 X 106 Degrees, the Temperature of the Corona
    1260 ASTRONOMY: MAXWELL PROC. N. A. S. obtained directly from the physical process, shows that the functions rt and d are nonnegative for x,y > 0. It follows from standard arguments that as A 0 these functions approach the solutions of (2). 4. Solution of Oriqinal Problem.-The solution of the problem posed in (2.1) can be carried out in two ways, once the functions r(y,x) and t(y,x) have been deter- mined. In the first place, since u(x) = r(y,x), a determination of r(y,x) reduces the problem in (2.1) to an initial value process. Secondly, as indicated in reference 1, the internal fluxes, u(z) and v(z) can be expressed in terms of the reflection and transmission functions. Computational results will be presented subsequently.

MAXWELL HARVARD UNIVERSITYt This paper deals briefly with present radio models of the solar atmosphere, and with three particular types of experimental programs in solar radio astronomy: radio heliographs, spectrum analyzers, and a sweep-frequency interferometer. The radio emissions from the sun, the only star from which radio waves have as yet been detected, consist of (i) a background thermal emission from the solar atmosphere, (ii) a slowly varying component, also believed to be thermal in origin, and (iii) nonthermal transient disturbances, sometimes of great intensity, which originate in localized active areas.

Magnetically confined coronae dominate in the cool half of the Hertzsprung-Russell diagram. Their radio emission is predominantly of nonthermal origin and has been identified as gyrosyn- chrotron radiation from mildly relativistic electrons, apart from some coherent emission mechanisms. Ionized winds are found in hot stars and in red giants. They are detected through their thermal, optically thick radiation, but synchrotron emission has been found in many systems as well. The latter is emitted presumably by shock-accelerated electrons in weak magnetic fields in the outer wind regions. Radio emission is also frequently detected in pre–main sequence stars and protostars and has recently been discovered in brown dwarfs. This review summarizes the radio view of the atmospheres of nondegenerate stars, focusing on energy release physics in cool coronal stars, wind phenomenology in hot stars and cool giants, and emission observed from young and forming stars. Eines habe ich in einem langen Leben gelernt, namlich,¨ dass unsere ganze Wissenschaft, an den Dingen gemessen, von kindlicher Primitivitat¨ ist—und doch ist es das Kostlichste,¨ was wir haben.

BOX 55, Rwamagana – Rwanda. 3Istituto Ricerche Solari (IRSOL), Università della Svizzera italiana (USI), CH-6605 Locarno-Monti, Switzerland. Correspondence: Theogene Ndacyayisenga ([email protected]) Abstract. This article summarizes the results of an analysis of solar radio bursts detected by the e-Compound Astronomical Low cost Low-frequency Instrument for spectroscopy and Transportable Observatory (e-CALLISTO) spectrometer hosted by the University of Rwanda, College of Education. The data analysed were detected during the first year (2014–2015) of the instrument operation. The Atmospheric Imaging Assembly (AIA) images on board the Solar Dynamics Observatory (SDO) 5 were used to check the location of propagating waves associated with type III radio bursts detected without solar flares. Using quick plots provided by the e-CALLISTO website, we found a total of 202 solar radio bursts detected by the CALLISTO station located in Rwanda. Among them, 5 are type IIs, 175 are type IIIs, and 22 type IVs radio bursts. It is found that all analysed type IIs and 37% of type III bursts are associated with impulsive solar flares while Type IV radio bursts are poorly ∼ associated with flares. Furthermore, all of the analysed type II bursts are associated with CMEs which is consistent with the 10 previous studies, and 44% of type IIIs show association with CMEs.

In the intervening years the Journal has undergone a variety of changes. In 1970 the National Newsletter was published along with the Journal, being bound with the regular pages of the Journal. In 1978 the National Newsletter was physically separated but still included with the Journal, and in 1989 it became simply the Newsletter/Bulletin and in 1991 the Bulletin. That continued until the eventual merger of the two publications into the new Journal in 1997.

The conditions can be calculated from first principles if the necessary boundary conditions are specified, namely the plasma density in the outer corona and the radial distance at which the plasma forces the closed magnetic field into an open geometry. Low frequency radio observations (ν . 200 MHz) of plasma and cyclotron emission from stars probe these magneto-ionic conditions. Here we report the detection of low-frequency (120–167 MHz) radio emission associated with the dMe6 star WX UMa.

  • Coherent Emission Mechanisms in Astrophysical Plasmas
    Reviews of Modern Plasma Physics manuscript No. (will be inserted by the editor) Coherent Emission Mechanisms in Astrophysical Plasmas D. B. Melrose Received: date / Accepted: date Abstract Three known examples of coherent emission in radio astronomical sources are reviewed: plasma emission, electron cyclotron maser emission (ECME) and pulsar radio emission. Plasma emission is a multi-stage mechanism with the first stage being gener- ation of Langmuir waves through a streaming instability, and subsequent stages involving partial conversion of the Langmuir turbulence into escaping radiation at the fundamental (F) and second harmonic (H) of the plasma frequency. The early development and subsequent refinements of the theory, motivated by application to solar radio bursts, are reviewed. The driver of the instability is faster electrons outpacing slower electrons, resulting in a positive gradient (df(vk)/dvk > 0) at the front of the beam. Despite many successes of the theory, there is no widely accepted explanation for type I bursts and various radio continua. The earliest models for ECME were purely theoretical, and the theory was later adapted and applied to Jupiter (DAM), the Earth (AKR), solar spike bursts and flare stars. ECME strongly favors the x mode, whereas plasma emission favors the o mode. Two drivers for ECME are a ring feature (implying df(v)/dv > 0) and a loss-cone feature. Loss-cone driven ECME was initially favored for all applications. The now favored driver for AKR is the ring-feature in a horseshoe distribution, which results from acceleration by a parallel electric on converging magnetic field lines. The driver in DAM and solar and stellar applications is uncertain.
