    Physical Processes in the Interstellar Medium

    Physical Processes in the Interstellar Medium Ralf S. Klessen and Simon C. O. Glover Abstract Interstellar space is filled with a dilute mixture of charged particles, atoms, molecules and dust grains, called the interstellar medium (ISM). Understand- ing its physical properties and dynamical behavior is of pivotal importance to many areas of astronomy and astrophysics. Galaxy formation and evolu- tion, the formation of stars, cosmic nucleosynthesis, the origin of large com- plex, prebiotic molecules and the abundance, structure and growth of dust grains which constitute the fundamental building blocks of planets, all these processes are intimately coupled to the physics of the interstellar medium. However, despite its importance, its structure and evolution is still not fully understood. Observations reveal that the interstellar medium is highly tur- bulent, consists of different chemical phases, and is characterized by complex structure on all resolvable spatial and temporal scales. Our current numerical and theoretical models describe it as a strongly coupled system that is far from equilibrium and where the different components are intricately linked to- gether by complex feedback loops. Describing the interstellar medium is truly a multi-scale and multi-physics problem. In these lecture notes we introduce the microphysics necessary to better understand the interstellar medium. We review the relations between large-scale and small-scale dynamics, we con- sider turbulence as one of the key drivers of galactic evolution, and we review the physical processes that lead to the formation of dense molecular clouds and that govern stellar birth in their interior.

    Oregon Star Party Advanced Observing List

    Welcome to the OSP Advanced Observing List In a sincere attempt to lure more of you into trying the Advanced List, each object has a page telling you what it is, why it’s interesting to observe, and the minimum size telescope you might need to see it. I’ve included coordinates, the constellation each object is located in, and either a chart or photo (or both) showing what the object looks like and how it’s situated in the sky. All you have to do is observe and enjoy the challenge. Stretch your skill and imagination - see something new, something unimaginably old, something unexpected Even though this is a challenging list, you don’t need 20 years of observing experience or a 20 inch telescope to be successful – although in some cases that will help. The only way to see these cool objects for yourself is to give them a go. Howard Banich, The minimum aperture listed for each object is a rough estimate. The idea is to Chuck Dethloff and show approximately what size telescope might be needed to successfully observe Matt Vartanian that particular object. The range is 3 to 28 inches. collaborated on this The visibility of each object assumes decently good OSP observing conditions. year’s list. Requirements to receive a certificate 1. There are 14 objects to choose from. Descriptive notes and/or sketches that clearly show you observed 10 objects are needed to receive the observing certificate. For instance, you can mark up these photos and charts with lines and arrows, and add a few notes describing what you saw.

    Chromospheric Activity Induced by Short-Period Planets A Search for Modulation of Ca II H &; K Emission by Evgenya Shkolnik B.Sc. (Physics and Mathematics), Dalhousie University, 1998 M.Sc. (Astronomy), The University of British Columbia, 2000 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate Studies (Department of Physics and Astronomy) We accept this thesis as conforming to the required standard THE UNIVERSITY OF BRITISH COLUMBIA December 4, 2003 © Evgenya Shkolnik, 2003 Abstract I have detected the first evidence of magnetic interaction between an extra- solar planet and its parent star. Of the > 100 extrasolar planets discovered to date, approximated 20% of them are '51 Peg'-type with a Jupiter-mass planet orbiting within 0.1 As- tronomical Units. The systems with the tightest orbits (P orb < 5 days) offer the best opportunity to observe a tidal or magnetic interaction between the planet and its parent star. Stellar chromospheric activity could be modu- lated in two ways. For magnetic interaction, the modulation is predicted to be at the orbital period with enhancement near the sub-planetary point (</> = 0). Tidal interaction would stimulate activity with a period of Porb/2 with enhancements near both <j> — 0 and 0.5. The Ca II H & K line reversals at 3968 and 3933 A are the best chro- mospheric activity indicators visible from the ground. I observed the H & K emission cores of five sun-like stars with short period planets: r Boo, HD179949, HD 209458, 51 Peg and v And.

I hope everybody has been enjoying this early cool front and the taste of fall that comes with it. More to our interests, I hope everybody has been enjoying the longer evenings thanks to our entering Fall. Soon, those nights will start even earlier as Daylight Savings time finally ends for the year— unfortunately, it may be the last Standard Time for some time. Legislation passed over the summer will mandate Louisiana doing away with Standard time if federal law allows, and a bill making it’s way through the US senate right not aims to do just that: so, if you prefer earlier sunsets, take the time to write your congressmen before it’s too late.

    Fixed Stars Interview with Diana K. Rosenberg by Edith Hathaway, USA

    Fixed Stars Interview with Diana K. Rosenberg By Edith Hathaway, USA ob Hand calls Diana K. Rosenberg “the leading authority on Fixed Stars.” She has spent the past 30 years researching the subject of Fixed Stars. Her primary interest R has always been research and teaching, rather than the consulting side of astrology. Her preferred astrological techniques outside of the realm of Fixed Stars include Uranian Astrology (90 Degree Dial, Planetary Pictures, etc.), Derived Houses, Planetary Nodes, and Solstice Points. Diana has been a resident of New York City her entire life, while my residence in NYC spanned only 7 years, and I moved westwards in the USA in Feb. 1983. Our paths first crossed in 1982 when I was a student in Diana’s Uranian Astrology classes in Manhattan, NY. From 1988 to the early 1990s I made a gradual shift from Uranian (tropical) to Vedic (sidereal) astrology, a subject Diana always intended to study, but Fixed Stars came to take up all of her time. She has always been fascinated with very ancient things, and the study of antiquity. A different portion of this interview, mainly on Fixed Stars, is being published simultaneously by ISAR Journal (Journal of the International Society for Astrological Research), both print and On-line versions. See http://www.isarastrology.com. This larger interview at Saptarishis covers only a few pages of the same material, but also much more from Diana on stars. It segues at times into a dialogue between us about Fixed stars, mundane astrology, the Vedic nakshatras, and the two zodiacs – tropical and sidereal (items #12 through 14), also about her life and birth chart, including my commentary on her Vedic chart, at her request (item #16).

  • NGC-7023 (Caldwell 4) (LBN 487) the Iris Nebula in Cepheus Introduction the Purpose of the Observer’S Challenge Is to Encourage the Pursuit of Visual Observing

    MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada October 2012 NGC-7023 (Caldwell 4) (LBN 487) The Iris Nebula in Cepheus Introduction The purpose of the observer’s challenge is to encourage the pursuit of visual observing. It is open to everyone that is interested, and if you are able to contribute notes, drawings, or photographs, we will be happy to include them in our monthly summary. Observing is not only a pleasure, but an art. With the main focus of amateur astronomy on astrophotography, many times people tend to forget how it was in the days before cameras, clock drives, and GOTO. Astronomy depended on what was seen through the eyepiece. Not only did it satisfy an innate curiosity, but it allowed the first astronomers to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings and that is the tradition we are stressing in the observers challenge. By combining our visual observations with our drawings, and sometimes, astrophotography (from those with the equipment and talent to do so), we get a unique understanding of what it is like to look through an eyepiece, and to see what is really there. The hope is that you will read through these notes and become inspired to take more time at the eyepiece studying each object, and looking for those subtle details that you might never have noticed before.

Here's the king, his wife and their pet lizard too. Well, his head anyway. High overhead in the autumn sky lies one of the most impressive stars and star forming regions in the galaxy. Both are located in the constellation of Cepheus (the king) which is bordered by Cygnus and Cassiopeia (among others). Cepheus is relatively easy to locate with it's brightest stars forming a the rather distinctive shape of a child's house. To the south of Cepheus, we find the huge stellar nursery IC 1396. At around 2.5 deg by just over 2 deg, this HII region is one of the largest star forming regions in the night sky and occupies around 16 times the area of the full moon. IC 1396 lies some 3000 light years from your backyard - and perhaps only slightly further from mine ;) - on any given night and contains a number of targets in it's own right. This area is packed with deep sky objects. You'll find the Elephant's Trunk Nebula (IC 1396a), the open cluster Trumpler 37, the dark nebulae B161, B367, B163, B162, B160, and B365, various multiple stars, and perhaps most impressive of all, Herschel's Garnet Star - the Variable Mu Cephei - in the region. - 1 - Small Wonders: Quick Peeks – Cepheus Tom Trusock – 10 / 08 Wide field Finder Chart, Facing North - about 9:30pm Early October Targets of Interest - 2 - Small Wonders: Quick Peeks – Cepheus Tom Trusock – 10 / 08 And speaking of Mu, that's a good place to start.
  • Star Forming Regions in Cepheus

    Star Forming Regions in Cepheus

    Handbook of Star Forming Regions Vol. I Astronomical Society of the Pacific, 2008 Bo Reipurth, ed. Star Forming Regions in Cepheus M´aria Kun Konkoly Observatory, H-1525 Budapest, P.O. Box 67, Hungary Zolt´an T. Kiss Baja Astronomical Observatory, P.O. Box 766, H-6500 Baja, Hungary Zolt´an Balog1 Steward Observatory, University of Arizona, 933 N. Cherry Av., Tucson AZ 85721, USA Abstract. The northern Milky Way in the constellation of Cepheus (100◦ ≤ l ≤ 120◦;0◦ ≤ b ≤ 20◦) contains several star forming regions. The molecular clouds of the Cepheus Flare region at b > 10◦, are sites of low and intermediate mass star for- mation located between 200 and 450 pc from the Sun. Three nearby OB associations, Cep OB2, Cep OB3, Cep OB4, located at 600–800 pc, are each involved in forming stars, like the well known high mass star forming region S140 at 900 pc. The reflection nebula NGC7129 around 1 kpc harbors young, compact clusters of low and intermedi- ate mass stars. The giant star forming complex NGC7538 and the young open cluster NGC7380, associated with the Perseus arm, are located at d> 2 kpc. 1. Overview In this chapter we describe the star forming regions of the constellation of Cepheus. A large scale map of the constellation, with the boundaries defined by IAU overlaid, and the most prominent star forming regions indicated, is shown in Fig. 1. This huge area of the sky, stretching between the Galactic latitudes of about 0◦ and +30◦, contains several giant star forming molecular cloud complexes located at various distances from arXiv:0809.4761v1 [astro-ph] 27 Sep 2008 the Sun.
