  • Planetary Nebulae
    Planetary Nebulae A planetary nebula is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives. The term "planetary nebula" is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects appeared to him to resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and has not been changed. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years. The mechanism for formation of most planetary nebulae is thought to be the following: at the end of the star's life, during the red giant phase, the outer layers of the star are expelled by strong stellar winds. Eventually, after most of the red giant's atmosphere is dissipated, the exposed hot, luminous core emits ultraviolet radiation to ionize the ejected outer layers of the star. Absorbed ultraviolet light energizes the shell of nebulous gas around the central star, appearing as a bright colored planetary nebula at several discrete visible wavelengths. Planetary nebulae may play a crucial role in the chemical evolution of the Milky Way, returning material to the interstellar medium from stars where elements, the products of nucleosynthesis (such as carbon, nitrogen, oxygen and neon), have been created. Planetary nebulae are also observed in more distant galaxies, yielding useful information about their chemical abundances. In recent years, Hubble Space Telescope images have revealed many planetary nebulae to have extremely complex and varied morphologies.

  • A Basic Requirement for Studying the Heavens Is Determining Where In
    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

Dark Nebula: We see it because of light it blocks. Emission Nebula: The cloud itself glows. Planetary Nebula Galaxies were once classed as nebulas, too. Supernova Remnant: Reflection Nebula: What’s left after a star goes “boom” Reflects light from a star. “nebula” is latin for mist, fog, or cloud. Tuesday, February 5, 2013 Origin of the Term ‘Planetary Nebula’ William Herschel: Philosophical Transactions of the Royal Society, 1785, Volume 75, Page 263 ff*: Planetary Nebulae “I shall conclude this paper with an account of a few heavenly bodies, that from their singular appearance leave me almost in doubt where to class them...being all over of an uniform brightness, which it differs from nebulae, it light seems however to be of the starry nature, which suffers not so much as the planetary disks are know to do, when much magnified. The planetary appearance of the first two is so remarkable that we can hardly suppose them to be nebulae; their light is so uniform, as well as vivid, the diameters so small and well defined as to make it almost improbable that they should belong to that species of bodies. On the other hand, the effect of different power seems to be much against their light’s being of a planetary nature, since it preserves its brightness nearly in the same manner as to the stars in similar trials.” He describes five planetaries (Six listed, 5 and 6 appear to be repeats): NGC 7293 (Helix), NGC 7662 (Blue Snowball), NGC 6369 (Little Ghost), NGC 6853 (Dumbbell), NGC 6894 (Diamond Ring) He makes two guesses in 1785 about what they are: Star clusters that can’t be resolved, or Dead or dying stars, possibly multiple stars falling into each other.

  • 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.

  • A Search for Cool Companions of Planetary Nebula Nuclei
    A SEARCH FOR COOL COMPANIONS OF PLANETARY NEBULA NUCLEI A. F. Bentley Department of Physical Sciences Eastern Montana College Billings, Montana 59101 At present only a small number of planetary nebulae are known to possess binary nuclei. Since approximately 2/3 of main sequence stars are mem- bers of binary or multiple star systems, one might expect a large frac- tion of PN central stars to have gravitationally bound companions. Ad- ditionally, late-type stars are more numerous, and due to their low lu- minosities would be difficult to detect by visual observational methods at distances where PN are typically found (^1 kpc). (Only 5 known PN are thought to be nearer than 0.5 kpc). It is thus possible, and in our view probable, that a significant number of PN nuclei possess cool com- panions, hitherto undetected. Since Κ and M stars emit a considerable fraction of their energy in the infrared, we calculated the feasibility of detecting them with the Wyoming InSb photometer, and found that such detections might be possi- ble out to distances of ^2 kpc. To date 13 objects have been observed, including a sample of planetaries with known binary nuclei to test our hypothesis. The results are listed below. Object IR Excess Remark Object IR Excess Remark NGC 7293 no NGC 6905 no NGC 6853 no detection NGC 6543 yes known binary NGC 246 yes known binary NGC 6572 yes known binary NGC 7008 ?

The observations were made using standard infrared techniques in the J, H, K, and L bands.

Cruz de La Palma, Spain 3 CTIO/NOAO, Casilla 603, La Serena, Chile Received 28 May 2002 / Accepted 23 April 2003 Abstract. We have measured angular dimensions of 312 planetary nebulae from their images obtained in Hα (or Hα + [NII]). We have applied three methods of measurements: direct measurements at the 10% level of the peak surface brightness, Gaussian deconvolution and second-moment deconvolution. The results from the three methods are compared and analysed. We propose a simple deconvolution of the 10% level measurements which significantly improves the reliability of these measurements for compact and partially resolved nebulae. Gaussian deconvolution gives consistent but somewhat underestimated diameters compared to the 10% measurements. Second-moment deconvolution gives results in poor agreement with those from the other two methods, especially for poorly resolved nebulae. From the results of measurements and using the conclusions of our analysis we derive the final nebular diameters which should be free from systematic differences between small (partially resolved) and extended (well resolved) objects in our sample. Key words. planetary nebulae: general 1. Introduction different results for many PNe. In the case of well resolved and fairly symmetric nebulae with a well defined outer rim the The angular dimensions belong to the most fundamental obser- problem is simple and different methods give consistent results.
