The other parts in the series are: Southern Planetaries Southern Galaxies Two Southern Galaxy Groups These observing notes were made in early July while my family was staying at the Magellan Observatory (astronomical farmstead) for eight nights. The observatory is in the southern tablelands of New South Wales between Goulburn and Canberra (roughly 3.5 hrs from Sydney) and is hosted by Zane Hammond and his wife Fiona. Viewing the showpiece southern globulars was high on my observing priorities for Australia. Because the center of the Milky Way wheels overhead from -35° latitude, the globular system is much better placed and several of the best globulars in the sky which are completely inaccessible from the north are well placed. In the August issue of S&T, Les Dalrymple (who I observed with one evening), ranked M13 no better than 8th among the best globulars visible from Australia. I'd still jack up its ranking a couple of notches, but it's just one of the weak runnerups to 47 Tucana and Omega Centauri viewed over 75° up in the sky and behind NGC 6752, 6397 and M22.

  • 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).

New improved distances and absolute ages for the Galactic globular clusters NGC 6397, NGC 6752, and 47 Tuc are obtained using the Main Sequence Fitting Method. We derived accurate estimates of reddening and metal abundance for these three clusters using a strictly differential procedure, where the Johnson B V and Str¨omgren b y colours and UVES high resolution spectra of turn-off stars and early subgiants belonging to the clusters− were compared to− similar data for field subdwarfs with accurate parallaxes measured by Hipparcos. The use of a reddening free temperature indicator (the profile of Hα) allowed us to reduce the error bars in reddening determinations to about 0.005 mag, and in metal abundances to 0.04 dex, in the scales defined by the local subdwarfs. Error bars in distances are then reduced to about 0.07 mag for each cluster, yielding ages with typical random errors of about 1 Gyr.

Baldwin,5 Mark Phillips,6 and Xiao-Wei Liu 3 Received 2005 May 6; accepted 2006 December 4 ABSTRACT The s-process should occur in all but the lower mass progenitor stars of planetary nebulae, and this should be re- flected in the chemical composition of the gas that is expelled to create the current planetary nebula shell. Weak for- bidden emission lines are expected from several s-process elements in these shells and have been searched for and in some cases detected in previous investigations. Here we extend these studies by combining very high signal-to-noise ratio echelle spectra of a sample of PNe with a critical analysis of the identification of the emission lines of Z > 30 ions. Emission lines of Br, Kr, Xe, Rb, Ba, and Pb are detected with a reasonable degree of certainty in at least some of the objects studied here, and we also tentatively identify lines from Te and I, each in one object. The strengths of these lines indicate enhancement of s-process elements in the central star progenitors, and we determine the abundances of Br, Kr, and Xe, elements for which atomic data relevant for abundance determination have recently become available. As representative elements of the ‘‘light’’ and ‘‘heavy’’s-process peaks, Kr and Xe exhibit similar enhancements over solar values, suggesting that PN progenitors experience substantial neutron exposure.

  • The Moon Greets the Planets in the November Dawn 4 November 2015, by David Dickinson
    The moon greets the planets in the November dawn 4 November 2015, by David Dickinson Watch the scene shift, as the moon joins the dance this weekend. The mornings of Friday, October 6th and Saturday, October 7th are key, as the moon passes just two degrees from the Jupiter and Mars pair and just over one degree from Venus worldwide. Similar close pairings of the moon and Venus adorn many national flags, possibly inspired by a close grouping of Venus and the moon witnessed by skywatchers of yore. Saturday November 7th is also a fine time to try your hand at seeing Venus in the daytime, using the nearby crescent moon as a guide. The moon will be only four days from New, and the pair will be 46 degrees west of the sun, an optimal situation as A tri-planetary grouping from the morning of October Venus just passed greatest western elongation 31st. Credit: Joseph Brimacombe 46.4 degrees west of the sun on October 26th. So did this past weekend's shift back to Standard Time for most of North America throw you for a loop? Coming the day after Halloween, 2015 was the earliest we can now shift back off Daylight Saving Time. Sunday won't fall on November 1st again until 2020. Expect evenings get darker sooner for northern hemisphere residents, while the planetary action remains in the dawn sky. Though Mercury has exited the morning twilight stage, the planets Jupiter, Venus and Mars continue to put on a fine show, joined by the waning crescent moon later this week.
