Central Coast Astronomy Virtual Star Party May 15Th 7Pm Pacific
Central Coast Astronomy Virtual Star Party May 15th 7pm Pacific Welcome to our Virtual Star Gazing session! We’ll be focusing on objects you can see with binoculars or a small telescope, so after our session, you can simply walk outside, look up, and understand what you’re looking at. CCAS President Aurora Lipper and astronomer Kent Wallace will bring you a virtual “tour of the night sky” where you can discover, learn, and ask questions as we go along! All you need is an internet connection. You can use an iPad, laptop, computer or cell phone. When 7pm on Saturday night rolls around, click the link on our website to join our class. CentralCoastAstronomy.org/stargaze Before our session starts: Step 1: Download your free map of the night sky: SkyMaps.com They have it available for Northern and Southern hemispheres. Step 2: Print out this document and use it to take notes during our time on Saturday. This document highlights the objects we will focus on in our session together.

I Nomi Delle Stelle
I nomi delle stelle Se state leggendo questa pagina perché volete acquistare il nome di una stella, visitate IAU Theme Buying Stars and Star Names. Altrimenti, proseguite con il testo sottostante. L'UAI intende delineare una distinzione tra i termini nome e designazione. In questo testo, così come in altre pubblicazioni dell'UAI, il nome si riferisce al termine (solitamente colloquiale) utilizzato per una stella nel linguaggio quotidiano, mentre la designazione è esclusivamente alfanumerica e viene usata quasi esclusivamente nei cataloghi ufficiali e nell'astronomia professionale. Storia dei cataloghi stellari La catalogazione delle stelle ha una lunga storia alle spalle. Sin dalla preistoria, culture e civiltà in tutto il mondo hanno dato dei propri nomi alle stelle più luminose e importanti nel cielo notturno. Attraversando le culture greca, latina e araba, alcuni nomi hanno subito pochi cambiamenti e altri sono in uso ancora oggi. Mentre l'astronomia si sviluppava e si evolveva nel corso dei secoli, sorgeva la necessità di un sistema di catalogazione universale, in base al quale le stelle più luminose (e quindi quelle più studiate) fossero conosciute secondo gli stessi appellativi, indipendentemente dal Paese o dalla cultura da cui provenivano gli astronomi. Per risolvere questo problema, gli astronomi durante il Rinascimento hanno tentato di produrre cataloghi stellari seguendo un insieme di regole. Il primo esempio, ancora oggi popolare, è stato introdotto da Johann Bayer nel suo atlante Uranometria del 1603. Bayer ha catalogato le stelle in ogni costellazione con lettere greche minuscole, seguendo l'ordine approssimativo della loro luminosità apparente, in modo che la stella più luminosa di una costellazione fosse solitamente (ma non sempre) etichettata come Alpha, la seconda più brillante fosse Beta, e così via. -
195 9Mnras.119. .255E Stellar Groups, Iv. the Groombridge
STELLAR GROUPS, IV. THE GROOMBRIDGE 1830 GROUP OF .255E HIGH VELOCITY STARS AND ITS RELATION TO THE GLOBULAR CLUSTERS 9MNRAS.119. Olm J. Eggen and Allan R. Sondage 195 (Communicated by the Astronomer Royal) (Received 1959 March 4) Summary The available proper motions and radial velocity data have been used to establish the existence of a moving group of subdwarfs (Groombridge 1830 ¿roup) which includes RR Lyrae. On the basis of the relationship between the observed ultra-violet excess and displacement below the normal main sequence, the subdwarfs in the Groombridge 1830 group are identified with main sequence stars in the globular clusters. This identification gives a modulus of m — M= i4m-2 for the globular cluster M13 with the result that ikTp-~ + om*5 for the z RR Lyrae variables and My= — 2m*3 for the brightest stars in the cluster. RR Lyrae itself, for which we derive ikfp~ + om*8 from the moving cluster parallax, is shown to obey the period-amplitude relation for the variables in M3 and to be reddened by om*o5 with respect to those variables. By equating the luminosity of RR Lyrae to the mean of the variables in M3 we obtain a modulus of m — M= i5m-o for the cluster. We have not derived this modulus in the logical way of fitting the M3 main sequence to the main sequence of the Groombridge 1830 group because the colour observations of the M3 main sequence stars may contain a systematic error. Because the presence of RR Lyrae variables in stellar groups may provide the only accurate calibration of the luminosities of these stars, it is important to make a systematic search for such groups. -

Frankfurt Pleiades Star Map 2
FRANKFURT PLEIADES STAR MAP 2 In investigating the Martian connection of the Pleiadian pattern of Frankfurt, one cannot avoid to address the origins at least in the propagation of this motif in the modern era and in all the financial powerhouses of today’s World Financial Oder. This is in part the Pleiades conspiracy as this modern version of the ‘Pleiadian Conspiracy’ started here in Frankfurt with the Rothschild dynasty by Amschel Moses Bauer, 1743. This critique is not meant to placate all those of the said family or those that work in such financial structures or businesses and specifically not those in Frankfurt. However the argument is that those behind the family apparatus are of a cabal that is connected to the allegiance of not the true GOD of the Universe, YHVH but to the false usurper Lucifer. It is Lucifer they worship and venerate as the ‘god of this world’ and is the God of Mammon according to Jesus’ assessment. According to research and especially based on The 13 Bloodlines of the Illuminati by Springmeier, the current financial domination of the world began in Frankfurt with Mayer Amschel. They were of Jewish extract but adhere more toward the Kabbalistic, Zohar, and ancient Babylonian secret mystery religion initiated by Nimrod after the Flood of Noah. The star Taygete corresponds to the Literaturahaus building. T he star Celaena corresponds to the Burgenamt Zentrales building. The star Merope corresponds to the area of the Timmitus und THE PLEIADES Hyperakusis Center. The star Alcyone corresponds to the Oper FINANCIAL DISTRICT The Bearing-Point building is Frankfurt or the Opera House. -

ALL RIGHTS RESERVED. Venture out under a clear night sky, in city or country, bright moon or dark moon, and you will see at least a few stars. Fortunately, the brightest stars visible offer a wide variety of characteristics that can be observed or computed easily. With this activity, students have the chance to see these bright stars and learn that these neighbor stars plotted on the appropriate map echo the construction of the whole Milky Way galaxy. Students will first familiarize themselves with the brighter stars in the evening sky. At first glance, the stars’ positions will appear random. Moving into the classroom, students will plot the positions of the stars in two different coordinate systems. A plot prepared using the stars’ positions in the “equatorial” coordinate system (essentially an expansion of latitude and longitude into the sky) will initially seem to present the apparent randomness of the stars’ positions. -
Abstract a Search for Extrasolar Planets Using Echoes Produced in Flare Events
ABSTRACT A SEARCH FOR EXTRASOLAR PLANETS USING ECHOES PRODUCED IN FLARE EVENTS A detection technique for searching for extrasolar planets using stellar flare events is explored, including a discussion of potential benefits, potential problems, and limitations of the method. The detection technique analyzes the observed time versus intensity profile of a star’s energetic flare to determine possible existence of a nearby planet. When measuring the pulse of light produced by a flare, the detection of an echo may indicate the presence of a nearby reflective surface. The flare, acting much like the pulse in a radar system, would give information about the location and relative size of the planet. This method of detection has the potential to give science a new tool with which to further humankind’s understanding of planetary systems.
