  • Binocular Universe: Aurigan Treasures
    Binocular Universe: Aurigan Treasures February 2012 Phil Harrington ead outside this evening and take a look high overhead. If you live in midnorthern latitudes, you will find a lone beacon cresting near the zenith as Hthe sky darkens. That's Capella, the Alpha (α) star of the constellation Auriga the Charioteer. Tracing back to ancient Rome, the name Capella translates as "She-Goat," a reference to the position it holds in the picture of the Charioteer. He is often portrayed as holding a goat and two kids in his arms. Above: Winter star map from Star Watch by Phil Harrington. Finder chart for this month's Binocular Universe, adapted from TUBA, www.philharrington.net/tuba.htm Today, we know that Capella is actually a binary star system lying some 42 light years away. Each of Capella's suns is classified as a type-G yellow star, like our Sun. That means that all three have roughly the same surface temperature, although our yellow dwarf Sun is only about one-tenth as large as either of the Capella giants. There is little hope of spotting the two Capella component stars through even the largest telescopes, since they are only separated by about 60 million miles, less than the distance from the Sun to Venus. The Charioteer’s pentagonal body highlights a wonderful area of the winter sky to scan with binoculars. There, you will find three of the season’s brightest open star clusters as well as an array of lesser known targets. M38, one of Auriga's three Messier open clusters, is centrally positioned within Auriga’s pentagonal body.

  • Asteroseismology of Β Cephei and Be Type Stars
    Asteroseismology of β Cephei and Be type stars by Kym Jeanette Frances Goss A thesis submitted to The University of Birmingham for the degree of Doctor of Philosophy School of Physics and Astronomy The University of Birmingham May 2012 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties. The intellectual property rights of the author or third parties in respect of this work are as defined by The Copyright Designs and Patents Act 1988 or as modified by any successor legislation. Any use made of information contained in this thesis/dissertation must be in accordance with that legislation and must be properly acknowledged. Further distribution or reproduction in any format is prohibited without the permission of the copyright holder. Abstract The thesis focuses on the asteroseismology of main sequence B-type stars, particularly β Cephei and Be stars. Photometric observations of these stars were analysed in order to detect stellar oscillations. The photometric data analysed in this thesis were collected using the Solar Mass Ejection Imager (SMEI). The analysis initially focussed on known β Cephei stars, to refine information on previously detected frequencies and detect further oscillations. A survey was then conducted using data from the SMEI instrument to search for further β Cephei stars. The results from this survey were analysed, and individual stars were examined in more detail which may possibly be β Cephei like. Due to the long duration of light curves obtained with the SMEI instrument, stellar oscillations can be analysed for evidence of amplitude and phase change.

  • RR Lyrae Stars As Seen by the Kepler Space Telescope
    RR Lyrae stars as seen by the Kepler space telescope Emese Plachy 1;2;3,Robert´ Szabo,´ 1;2;3∗ 1Konkoly Observatory, Research Centre for Astronomy and Earth Sciences, Konkoly Thege Miklos´ ut´ 15-17, H-1121 Budapest, Hungary 2MTA CSFK Lendulet¨ Near-Field Cosmology Research Group 3ELTE Eotv¨ os¨ Lorand´ University, Institute of Physics, Budapest, Hungary Correspondence*: Robert´ Szabo´ [email protected] ABSTRACT The unprecedented photometric precision along with the quasi-continuous sampling provided by the Kepler space telescope revealed new and unpredicted phenomena that reformed and invigorated RR Lyrae star research. The discovery of period doubling and the wealth of low- amplitude modes enlightened the complexity of the pulsation behavior and guided us towards nonlinear and nonradial studies. Searching and providing theoretical explanation for these newly found phenomena became a central question, as well as understanding their connection to the oldest enigma of RR Lyrae stars, the Blazhko effect. We attempt to summarize the highest impact RR Lyrae results based on or inspired by the data of the Kepler space telescope both from the nominal and the K2 missions. Besides the three most intriguing topics, the period doubling, the low-amplitude modes, and the Blazhko effect, we also discuss the challenges of Kepler photometry that played a crucial role in the results. The secrets of these amazing variables, uncovered by Kepler, keep the theoretical, ground-based and space-based research inspired in the post-Kepler era, since light variation of RR Lyrae stars is still not completely understood. Keywords: RR Lyrae stars, Kepler spacecraft, Blazkho effect, pulsating variable stars, horizontal-branch stars, pulsation, asteroseismology, nonradial oscillations 1 INTRODUCTION RR Lyrae stars are large-amplitude, horizontal-branch pulsating stars which serve as tracers and distance indicators of old stellar populations in the Milky Way and neighboring galaxies.

  • Appendix 1: Telescope Limiting-Magnitude and Resolution
    Appendix 1: Telescope Limiting-Magnitude and Resolution Listed below are limiting-magnitudes and resolution values for a variety of common-sized ( SIZE in inches) backyard telescopes in use today, ranging from 2- to 14-in. in aperture. (The 2.4-in. entry is the ubiquitous 60 mm refractor, of which there are perhaps more than any other telescope in the world!) Values for the minimum visual magnitude ( MAG .) listed here are for single stars and are only very approximate, since experienced keen-eyed observers may see as much as a full magnitude fainter under excellent sky conditions. Companions to visual double stars—especially those in close proximity to a bright primary—are typically much more dif fi cult to see than is a star of the same magnitude placed alone in the eye- piece fi eld. Among the many variables involved are light pollution, sky conditions, optical quality, mirror and lens coatings, eyepiece design, obstructed or unob- structed optical system, color (spectral type) of the star, and even the age of the observer. Only a few representative limiting magnitudes are given here (in incre- ments of increasing aperture), as an indication of what an observer might typically expect to see in various sized telescopes. Three different values in arc-seconds are listed for resolution, which are for two stars of equal brightness and of about the sixth magnitude. These fi gures differ signi fi cantly for brighter, fainter and, espe- cially, unequal pairs. DAWES is the value based on Dawes’ Limit ( R = 4.56/A), RAYLEIGH on the Rayleigh Criterion ( R = 5.5/D), and MARKOWITZ on Markowitz’s Limit ( R = 6.0/D).

Paál (eds.): Evolution: from cosmogenesis to biogenesis KFKI 1990 50/C ABSTRACT The Volume contains the material of an interdisciplinary evolution symposium The purpose was to shed some light on possible connections between steps of evolution of matter on different levels of organisation. The topics involved are as follow: cosmogenesis; galactic and stellar evolution, formation and evolution of the solar system; global atmospheric and tectonic changes of Earth; viral evolution; phytogeny and evolution of terrestrial lile; evolution of neural system; hominization The material also includes some discussions of the underlying phenomena and laws of Nature.
