NOVA REPORTNOVA 2003 - 2005 NOVA REPORT 2003-2005 Illustration on the front cover Spitzer image of the Serpens molecular cloud mapped by the ‘Cores to Disks’ Legacy program combining data at 3.6, 8 and 24 µm. The inserts show a newly- discovered cluster of young stars as well as the young star VV Ser with its shadow disk. Follow-up IRS spectroscopy shows that the newly discovered sources cover a range of evolutionary stages, from deeply embedded YSOs to young stars with optically thin disks (based on Pontoppidan, Geers, Merin, van Dishoeck et al. 2006). Superposed is a schematic view of a flaring circumstellar disk and the VLTI-MIDI spectra observed of the inner and outer regions of a Herbig Ae disk (van Boekel, Waters et al. 2005). Also superposed is part of the JCMT 345 GHz spectral survey of the low- mass protostar IRAS 16293-2422, showing strong lines of gaseous methanol (Tielens, Helmich et al. 2006).

Introduction In 1997 the Ministry of Education, Culture and Science initiated a ten-year program, the so-called ‘In Depth Strategy’ to identify and stimulate national focus points of excellent scientific research, which also train outstanding young scientists. To meet the selection criteria, such focus points were compared with the best foreign institutes in their field of research. The Netherlands Organi- zation for Scientific Research (NWO) selected six such National Research Combinations from 34 proposals covering all academic disciplines. The Netherlands Research School for Astronomy, NOVA, was ranked highest among the six, and received an initial grant of 21 M€ to support its proposed innovative research program entitled ‘The Life-Cycle of Stars and Galaxies’ through mid 2005. The NOVA program started in 1999, with a budget profile that ramped up to full strength by 2002. The current report describes activities in 2003, 2004 and 2005. This period saw many new appoint- ments on the permanent and temporary research and technical staff, and continuation of a strong instrumentation program. NOVA funds nearly 25% of the research and technical positions at the five participating universities, an active workshop and visitor program, and outreach efforts. The ambitious instrumentation program is on track, and has generated substantial additional funding. As a result, the quality and quantity of the research output of Dutch astronomy, and of the graduate education, continues to increase. In 2003 NWO carried out a mid-term review of the achievements of the program, and of the plans through 2008, which had been developed with input from NOVA’s International Advisory Board. The resulting very positive recommendation led to a further allocation of nearly 15 M€ to support the program through 2008. Sadly, the chair of the International Advisory Board, professor John Bahcall of the Institute for Advanced Study, and one of the most distinguished astronomers any- where in the world, passed away in August 2005, well before his time. The year 2005 also saw the retirement of van den Heuvel, who had served on the NOVA Board since 1992, and chaired it for many years. He helped shape Dutch astronomy over many decades, and had a key role in the development of the entire NOVA program. His new-found freedom to concentrate on research again is eminently deserved. Highlights for the period 2003-2005 include: • A tremendous variety of new astrophysical results which are summarized in chapter 3 of this report; • A total of 58 PhD degrees in astronomy awarded at the five NOVA institutions (chapter 4), with cum laude for van de Ven; • The excellent performance of MIDI on ESO's VLTI, SINFONI on ESO's VLT and PuMa on the WSRT. MIDI is the first NOVA instrumentation project for which hardware and software deliv- ery was completed. It is the first common-user

  • Binocular Challenges

    Binocular Challenges

    This page intentionally left blank Cosmic Challenge Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for viewing by the naked eye, through binoculars, to the largest backyard telescopes. Philip S. Harrington is the author of eight previous books for the amateur astronomer, including Touring the Universe through Binoculars, Star Ware, and Star Watch. He is also a contributing editor for Astronomy magazine, where he has authored the magazine’s monthly “Binocular Universe” column and “Phil Harrington’s Challenge Objects,” a quarterly online column on Astronomy.com.

Nous évoquerons aussi quelques notions sur les trous noirs et le « Big Bang ». Par contre les informations concernant les planètes seront évoquées assez sommairement dans la mesure où sont déjà rédigés des textes spécifiques sur chacune des planètes : Mercure, Vénus la Terre, Mars, Jupiter, Saturne, Uranus, Neptune, les planètes naines, ainsi que les Instruments de l’Astronomie et la Conquête spatiale. A) Naissance d’une étoile – Présence d’une nébuleuse La naissance des étoiles ou formation stellaire, voire stellogénèse ou stellogonie, est un domaine de recherche en astrophysique qui consiste en l'étude des modes de formation des étoiles et des systèmes planétaires. Les étoiles en formation sont fréquemment appelées "étoiles jeunes". En cosmologie, la formation des étoiles n’a lieu que durant la période de l’univers nommée « ère stellifère ». Selon le scénario actuellement admis, confirmé par l'observation, les étoiles se forment en groupe à partir de la contraction gravitationnelle d'une nébuleuse, un nuage de gaz et de poussière, qui se fragmente en plusieurs cœurs protostellaires.

During the disk-disk merger (~400 Myr ago) this galaxy produced the largest young massive star cluster population known, including two clusters above 10^7 Msun, a factor of 100 more massive than typical globular clusters in the Milky Way. We propose ACS-HRC observations of 3 fields in NGC 7252 in order to explore the detailed properties, i.e. luminosity profiles, of these massive star clusters. These observations will be able to test massive cluster formation mechanisms (e.g. the cluster merger scenario) as well as the possible tidal erosion and truncation of the outer regions of the clusters by the galactic tidal field. These observations will compliment our large on-going study using archival HST data, of star cluster profiles outside the Local Group. The cluster population in NGC 7252 will extend our sample in cluster mass by an order of magnitude. ====================================================================== Proposal Category: GO Scientific Category: COOL STARS ID: 11555 Title: Transition Region and Chromospheric Activity on Low Metallicity Arcturus Moving Group "Alien" Dwarfs PI: Alexander Brown PI Institution: University of Colorado at Boulder How does low metallicity affect the heating and resultant temperature structure of the chromospheres, transition regions, and coronae of old solar- like dwarf stars? The Arcturus Moving Group is very likely a remnant of the merger of a dwarf galaxy with the Milky Way Galaxy in the distant (~ 7- 8 Gyr) past.

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.
