I hope everyone in our club gets out to Mount Laguna and enjoys reading about their interesting telescopes located at the Mount Laguna Observatory. Mount Laguna Observatory (MLO) was dedicated on June 19, 1968 in conjunction with the Summer meeting of the Astronomical Society (cont'd on page 6 through 9) of the Pacific, which was hosted by the SDSU Astronomy Department (D.B. Wood, 1968, Publ. Astron. Soc. Pac. 80, 633). The dedication occurred only seven years after the CONTENTS Astronomy Department became a separate entity on the SDSU campus. July 2001 Vol. XXXVII Issue 07 The original funding for the Published Monthly by the observatory facilities grew from a San Diego Astronomy Association 75¢/$8.00 year grant from the National Science Incorporated in California in 1963 Foundation to Director (now Emeritus) Burt Nelson for the study of eclipsing binary stars, with matching funds supplied by the State of California.

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr.

  • The Electric Sun Hypothesis
    Basics of astrophysics revisited. II. Mass- luminosity- rotation relation for F, A, B, O and WR class stars Edgars Alksnis [email protected] Small volume statistics show, that luminosity of bright stars is proportional to their angular momentums of rotation when certain relation between stellar mass and stellar rotation speed is reached. Cause should be outside of standard stellar model. Concept allows strengthen hypotheses of 1) fast rotation of Wolf-Rayet stars and 2) low mass central black hole of the Milky Way. Keywords: mass-luminosity relation, stellar rotation, Wolf-Rayet stars, stellar angular momentum, Sagittarius A* mass, Sagittarius A* luminosity. In previous work (Alksnis, 2017) we have shown, that in slow rotating stars stellar luminosity is proportional to spin angular momentum of the star. This allows us to see, that there in fact are no stars outside of “main sequence” within stellar classes G, K and M. METHOD We have analyzed possible connection between stellar luminosity and stellar angular momentum in samples of most known F, A, B, O and WR class stars (tables 1-5). Stellar equatorial rotation speed (vsini) was used as main parameter of stellar rotation when possible. Several diverse data for one star were averaged. Zero stellar rotation speed was considered as an error and corresponding star has been not included in sample.

Such field structures give rise to stellar activity, which manifests itself at all heights of the atmosphere. Observations of uneven distributions of flux across the stellar disk have led to the discovery of photospheric starspots, chromospheric plage areas, and coronal holes.

    NICU GOGA CARTE DE ASTRONOMIE Editura REVERS CRAIOVA, 2010 Referent ştiinţific: Prof. univ.dr. Radu Constantinescu Editura Revers ISBN: 978-606-92381-6-5 2 În contextul actual al restructurării învăţământului obligatoriu, precum şi al unei manifeste lipse de interes din partea tinerei generaţii pentru studiul disciplinelor din aria curiculară Ştiinţe, se impune o intensificare a activităţilor de promovare a diferitelor discipline ştiinţifice. Dintre aceste discipline Astronomia ocupă un rol prioritar, având în vedere că ea intermediază tinerilor posibilitatea de a învăţa despre lumea în care trăiesc, de a afla tainele şi legile care guvernează Universul. În plus, anul 2009 a căpătat o co-notaţie specială prin declararea lui de către UNESCO drept „Anul Internaţional al Astronomiei”. În acest context, domnul profesor Nicu Goga ne propune acum o a doua carte cu tematică de Astronomie. După apariţia lucrării Geneza, evoluţia şi sfârşitul Universului, un volum care s+a bucurat de un real succes, apariţia lucrării „Carte de Astronomie” reprezintă un adevărat eveniment editorial, cu atât mai mult cu cât ea constitue în acelaşi timp un material monografic şi un material cu caracter didactic. Cartea este structurată în 13 capitole, trecând în revistă problematica generală a Astronomiei cu puţine elemente de Cosmologie. Cartea îşi propune şi reuşeşte pe deplin să ofere răspunsuri la câteva întrebări fundamentale şi tulburătoare legate de existenţa fiinţei umane şi a dimensiunii cosmice a acestei existenţe, incită la dialog şi la dorinţa de cunoaştere. Consider că, în ansamblul său, cartea poate contribui la îmbunătăţirea educaţiei ştiinţifice a tinerilor elevi şi este deosebit de utilă pentru toţi „actorii” implicaţi în procesul de predare-învăţare: elevi, părinţi, profesori.

In an hour's exposure, the stars revealed the rotation of the earth by recording on the photographic plate a fraction of the apparent daily circle of each. The group arrangement of the Little Dipper with the Pole Star at the end of the handle has been indicated at the initial position and the trails show its subsequent motion.
