Stars and Their Spectra: an Introduction to the Spectral Sequence Second Edition James B
Cambridge University Press 978-0-521-89954-3 - Stars and Their Spectra: An Introduction to the Spectral Sequence Second Edition James B. Kaler Index More information Star index Stars are arranged by the Latin genitive of their constellation of residence, with other star names interspersed alphabetically. Within a constellation, Bayer Greek letters are given first, followed by Roman letters, Flamsteed numbers, variable stars arranged in traditional order (see Section 1.11), and then other names that take on genitive form. Stellar spectra are indicated by an asterisk. The best-known proper names have priority over their Greek-letter names. Spectra of the Sun and of nebulae are included as well.

August 2017 BRAS Newsletter
August 2017 Issue Next Meeting: Monday, August 14th at 7PM at HRPO nd (2 Mondays, Highland Road Park Observatory) Presenters: Chris Desselles, Merrill Hess, and Ben Toman will share tips, tricks and insights regarding the upcoming Solar Eclipse. What's In This Issue? President’s Message Secretary's Summary Outreach Report - FAE Light Pollution Committee Report Recent Forum Entries 20/20 Vision Campaign Messages from the HRPO Perseid Meteor Shower Partial Solar Eclipse Observing Notes – Lyra, the Lyre & Mythology Like this newsletter? See past issues back to 2009 at http://brastro.org/newsletters.html Newsletter of the Baton Rouge Astronomical Society August 2017 President’s Message August, 21, 2017. Total eclipse of the Sun. What more can I say. If you have not made plans for a road trip, you can help out at HRPO. All who are going on a road trip be prepared to share pictures and experiences at the September meeting. BRAS has lost another member, Bart Bennett, who joined BRAS after Chris Desselles gave a talk on Astrophotography to the Cajun Clickers Computer Club (CCCC) in January of 2016, Bart became the President of CCCC at the same time I became president of BRAS. The Clickers are shocked at his sudden death via heart attack. Both organizations will miss Bart. His obituary is posted online here: http://www.rabenhorst.com/obituary/sidney-barton-bart-bennett/ Last month’s meeting, at LIGO, was a success, even though there was not much solar viewing for the public due to clouds and rain for most of the afternoon. BRAS had a table inside the museum building, where Ben and Craig used material from the Night Sky Network for the public outreach. -

SPITZER: Accretion in Low Mass Stars and Brown Dwarfs in the Lambda
SPITZER: Accretion in Low Mass Stars and Brown Dwarfs in the Lambda Orionis Cluster1 David Barrado y Navascu´es Laboratorio de Astrof´ısica Espacial y F´ısica Fundamental, LAEFF-INTA, P.O. Box 50727, E-28080 Madrid, SPAIN [email protected] John R. Stauffer Spitzer Science Center, California Institute of Technology, Pasadena, CA 91125 Mar´ıaMorales-Calder´on, Amelia Bayo Laboratorio de Astrof´ısica Espacial y F´ısica Fundamental, LAEFF-INTA, P.O. Box 50727, E-28080 Madrid, SPAIN Giovanni Fazzio, Tom Megeath, Lori Allen Harvard Smithsonian Center for Astrophysics, Cambridge, MA 02138 Lee W. Hartmann, Nuria Calvet Department of Astronomy, University of Michigan ABSTRACT We present multi-wavelength optical and infrared photometry of 170 previously known low mass stars and brown dwarfs of the 5 Myr Collinder 69 cluster (Lambda Orionis). The new photometry supports cluster membership for most of them, with less than 15% of the previous candidates identified as probable non-members. The near infrared photometry allows us to identify stars with IR excesses, and we find that the Class II population is very large, around arXiv:0704.1963v1 [astro-ph] 16 Apr 2007 25% for stars (in the spectral range M0 - M6.5) and 40% for brown dwarfs, down to 0.04 M⊙, despite the fact that the Hα equivalent width is low for a significant fraction of them. In addition, there are a number of substellar objects, classified as Class III, that have optically thin disks. The Class II members are distributed in an inhomogeneous way, lying preferentially in a filament running toward the south-east. -

In a representative sample of stars earlier than F5 (29 stars), we find a population of 9 stars with a varying degree of moderate 24µm excess comparable to those produced by debris disks in older stellar groups. -
Astronomers Need Your Help!
Citizen Science with variable stars Brought to you by the AAVSO, the Naonal Science Foundaon and Your Universe Astronomers need your help! Variable stars are stars that change in brightness over 1me. There are too many for professional astronomers to monitor alone. So, we need your help to monitor these stars over days, weeks and years. This guide will help you find some bright variable stars, measure their brightness and Ci#zenSky is a collaboraon of then submit the measurements to assist the American Associaon of professional astronomers. Variable Star Observers (AAVSO), the University of Denver, the Adler Planetarium, the Johns Hopkins University Par1cipate in one of the oldest ci1zen science and the California Academies projects in history! Thousands of people just of Science with support from the Naonal Science like you are also helping out. Astronomers Foundaon. need large numbers of people to get the amount of precision they need to do their research. You are the key. Header artwork is reproduced with permission from Sky & Telescope magazine (www.skyandtelescope.com) This is a Light Curve It shows how a star’s brightness changes over 1me. Light curves are a fundamental tool for variable star astronomy. They are relavely simple and easy to grasp. They are simply a graph of brightness (Y axis) vs. 1me (X axis). Brightness increases as you go up the graph and 1me advances as you move to the right. The brightness of a star is measured in units of “magnitude”. No1ce that the magnitude scale on the graph above shows smaller numbers as the star gets brighter and larger numbers as the star gets fainter. -
Popular Names of Deep Sky (Galaxies,Nebulae and Clusters) Viciana’S List
POPULAR NAMES OF DEEP SKY (GALAXIES,NEBULAE AND CLUSTERS) VICIANA’S LIST 2ª version August 2014 There isn’t any astronomical guide or star chart without a list of popular names of deep sky objects. Given the huge amount of celestial bodies labeled only with a number, the popular names given to them serve as a friendly anchor in a broad and complicated science such as Astronomy The origin of these names is varied. Some of them come from mythology (Pleiades); others from their discoverer; some describe their shape or singularities; (for instance, a rotten egg, because of its odor); and others belong to a constellation (Great Orion Nebula); etc. The real popular names of celestial bodies are those that for some special characteristic, have been inspired by the imagination of astronomers and amateurs. The most complete list is proposed by SEDS (Students for the Exploration and Development of Space). Other sources that have been used to produce this illustrated dictionary are AstroSurf, Wikipedia, Astronomy Picture of the Day, Skymap computer program, Cartes du ciel and a large bibliography of THE NAMES OF THE UNIVERSE. If you know other name of popular deep sky objects and you think it is important to include them in the popular names’ list, please send it to [email protected] with at least three references from different websites. If you have a good photo of some of the deep sky objects, please send it with standard technical specifications and an optional comment. It will be published in the names of the Universe blog. It could also be included in the ILLUSTRATED DICTIONARY OF POPULAR NAMES OF DEEP SKY.
