Snake River Skies The Newsletter of the Magic Valley Astronomical Society www.mvastro.org Membership Meeting President’s Message Tim Frazier Saturday, April 14th 2018 April 2018 7:00pm at the Herrett Center for Arts & Science College of Southern Idaho. It really is beginning to feel like spring. The weather is more moderate and there will be, hopefully, clearer skies. (I write this with some trepidation as I don’t want to jinx Public Star Party Follows at the it in a manner similar to buying new equipment will ensure at least two weeks of Centennial Observatory cloudy weather.) Along with the season comes some great spring viewing. Leo is high overhead in the early evening with its compliment of galaxies as is Coma Club Officers Berenices and Virgo with that dense cluster of extragalactic objects. Tim Frazier, President One of my first forays into the Coma-Virgo cluster was in the early 1960’s with my [email protected] new 4 ¼ inch f/10 reflector and my first star chart, the epoch 1960 version of Norton’s Star Atlas. I figured from the maps I couldn’t miss seeing something since Robert Mayer, Vice President there were so many so closely packed. That became the real problem as they all [email protected] appeared as fuzzy spots and the maps were not detailed enough to distinguish one galaxy from another. I still have that atlas as it was a precious Christmas gift from Gary Leavitt, Secretary my grandparents but now I use better maps, larger scopes and GOTO to make sure [email protected] it is M84 or M86. -

The nights are starting earlier and earlier as the weather becomes more and more comfortable and all of our old favorites of the fall and winter skies really start finding their places right where they belong. October was a busy month for us, with several big functions at the Observatory, including two oppositions and two more all night celebrations. By comparison, November is looking fairly calm, the big focus there is going to be our third annual Natural Sky Conference on the 13th, which I’m encouraging people who care about the state of light pollution in our city and the surrounding area to get involved in. -

Dass es auch anders geht, zeigt das Schwerpunktthema „Astronomie mit klei- nem Budget und einfachen Mitteln“ in diesem Heft.

Fy05 Accomplishments and Fy06 Plans Helmut A. Abt
Appendix A NOAO SCIENTIFIC STAFF: FY05 ACCOMPLISHMENTS AND FY06 PLANS ¬New appointment in FY05 S Non-NSF (external) funding ±Term ended in FY05 HELMUT A. ABT, Emeritus Astronomer Research Interests Evolutionary stellar problems, stellar characteristics, publication studies FY05 Accomplishments Abt and C. Boonyarak (U. Thailand) studied rotation velocities of stars in binaries. It was known that those with periods shorter than several days all have synchronized rotational and orbital motions. They found that binaries with periods up to 500 days have reduced rotational velocities due to tidal interactions. Abt found that the eccentricities in binaries vary from zero in close binaries to an average of 0.5 in binaries with periods greater than 1000 days. In the initial formation of binaries, all eccentricities are equally probable. FY06 Plans Abt is trying to understand the hot inner disks that occur around, at any one time, one-quarter of the rapidly- rotating A dwarfs. These disks have no connection with the outer cool dust disks found around many stars like Vega and beta Pictoris. These disks come and go on time scales of decades. Such stars do not occur in the low-density Local Interstellar Bubble, so they are material accreted from the interstellar medium. Theoretical aspects of the physical processes is being done with M. Marlborough (U. Western Ontario). TAFT E. ARMANDROFF, Astronomer (Director, NOAO Gemini Science Center) Research Interests Stellar populations in the Galaxy and nearby galaxies; dwarf spheroidal galaxies; globular clusters FY05 Accomplishments Armandroff has been studying the dwarf spheroidal satellite galaxies of M31 in collaboration with Da Costa (RSAA/ANU), Pritzl (Macalester), and Jacoby (WIYN). -

Late Stages of Stellar Evolution-Herschel's Contributions
Late Stages of Stellar Evolution - Herschel’s contributionsI Leen Decin∗ Instituut voor Sterrenkunde, Katholieke Universiteit Leuven, Celestijnenlaan 200D, 3001 Leuven, Belgium. Sterrenkundig Instituut Anton Pannekoek, University of Amsterdam, Science Park 904, NL-1098 Amsterdam, The Netherlands Abstract Cool objects glow in the infrared. The gas and solid-state species that escape the stellar gravitational attraction of evolved late-type stars in the form of a stellar wind are cool, with temperatures typically ∼<1500 K, and can be ideally studied in the infrared. These stellar winds create huge extended circumstellar envelopes with extents approaching 1019 cm. In these envelopes, a complex kinematical, thermodynamical and chemical interplay determines the global and local struc- tural parameters. Unraveling the wind acceleration mechanisms and deriving the complicated structure of the envelopes is important to understand the late stages of evolution of ∼97% of stars in galaxies as our own Milky Way. That way, we can also assess the significant chemical enrichment of the interstellar medium by the mass loss of these evolved stars. The Herschel Space Observatory is uniquely placed to study evolved stars thanks to the excellent capabilities of the three in- frared and sub-millimeter instruments on board: PACS, SPIRE and HIFI. In this review, I give an overview of a few important results obtained during the first two years of Herschel observations in the field of evolved low and intermediate mass stars, and I will show how the Herschel observations can solve some historical questions on these late stages of stellar evolution, but also add some new ones. arXiv:1212.4861v1 [astro-ph.SR] 19 Dec 2012 Keywords: Stars: AGB and post-AGB, Stars: mass loss, Stars: circumstellar matter, infrared astronomy IHerschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. -

This Index is Copyright © 2007-2008, R. L. McNish, All Rights Reserved. About This Publication This Index to Astronomy Magazine's Atlas of the Stars was created to augment the Atlas which was published by Kalmbach Publishing Co. This Index was independently created by close examination of every object identified on all 24 double page maps in the Atlas then combining all the results into the 7 complete indices. Additionally, the author created the diagrams on the next 2 pages to show the overlapping relationships of all the Atlas maps in the Northern and Southern hemispheres of the sky. A page of "Errata" was also added as part of the process. If you find other mistakes in the Atlas I would be interested in noting them in the Errata section.

The scientific community had some great observations in 2016: It’s announced Public Star Party Follows at the Gravitational Waves* had been detected and supernova shockwaves, and has even Centennial Observatory been spotted the binary companion in a Type Ia supernova. Club Officers The last two discoveries came in March; while those observers were able to get Robert Mayer, President access to the stars, unfortunately, MVAS members didn’t get to see anything at [email protected] Castle Rocks State Park in March from their viewpoint in the lodge, but that won’t 208-312-1203 discourage us – and should make use even more eager for April. Paul McClain, Vice President We’ll open up matters with the Messier Marathon at the Jerome Gun Club. Due a [email protected] scheduling conflict, that event has been moved to Saturday, April 2, with Friday, April 8 set as a back-up date. Bring a scope and even bring a friend. Those who Gary Leavitt, Secretary need a scope should contact me as soon as possible to check out a club scope. [email protected] We’re looking forward to hear about what you’ve seen. 208-731-7476 Then, on Saturday, April 9, is the regular club meeting. This month's meeting will Jim Tubbs, Treasurer / ALCOR feature guest speaker Tom Davis, a widely published astrophotographer.
