  • 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).

Harris* David Dunlap Observatory, Richmond Hill, Ontario Received 1974 September 16; revised 1975 June 18 ABSTRACT Radial-velocity observations and MK classifications have been used to study evolved stars in 25 open clusters. Published data on stars in 72 additional clusters are rediscussed and com- bined with the observations friade in this investigation to yield positions in the Hertzsprung- Russell diagram for 559 evolved stars in 97 clusters. Ages for the parent clusters were estimated from the main-sequence turnoff points, earliest spectral types, and bluest stars in the clusters themselves. The evolved stars were sorted into six age groups ranging from 4 x 106 yr to 4 x 108 yr, and the composite H-R diagram for each age group was then used to study the evolutionary tracks for stars of various masses. The observational results were found to be in reasonably good agreement with recent theoretical computations. The composite color-magnitude diagrams were found to be strikingly different from those of the rich open clusters in the Magellanic Clouds. At a given age the red giants in the Small Magellanic Cloud and the Large Magellanic Cloud clusters are brighter and bluer than their galactic counterparts. It is suggested that these effects may be accounted for by differences in metal abundance. Subject headings: clusters: open — galaxies: Magellanic Clouds — radial velocities — stars : evolution — stars : late-type — stars : spectral classification 1.

  • Open Clusters
    Open Clusters Open clusters (also known as galactic clusters) are of tremendous importance to the science of astronomy, if not to astrophysics and cosmology generally. Star clusters serve as the "laboratories" of astronomy, with stars now all at nearly the same distance and all created at essentially the same time. Each cluster thus is a running experiment, where we can observe the effects of composition, age, and environment. We are hobbled by seeing only a snapshot in time of each cluster, but taken collectively we can understand their evolution, and that of their included stars. These clusters are also important tracers of the Milky Way and other parent galaxies. They help us to understand their current structure and derive theories of the creation and evolution of galaxies. Just as importantly, starting from just the Hyades and the Pleiades, and then going to more distance clusters, open clusters serve to define the distance scale of the Milky Way, and from there all other galaxies and the entire universe. However, there is far more to the study of star clusters than that. Anyone who has looked at a cluster through a telescope or binoculars has realized that these are objects of immense beauty and symmetry. Whether a cluster like the Pleiades seen with delicate beauty with the unaided eye or in a small telescope or binoculars, or a cluster like NGC 7789 whose thousands of stars are seen with overpowering wonder in a large telescope, open clusters can only bring awe and amazement to the viewer. These sights are available to all.

  • Summer Sp Target Information
    SUMMER SP TARGET INFORMATION ALGIEBA (g LEO) BASIC INFORMATION OBJECT TYPE: Binary Star CONSTELLATION: Leo BEST VIEW: Late April DISCOVERY: Known to Ancients DISTANCE: 131 ly BINARY SEPARATION: 4” (170 AU) ORBITAL PERIOD: ~500 yr. APPARENT MAGNITUDE: 1.98 DISTANCE DETERMINATION After measuring the shift in position of the star relative to background stars as Earth orbits the Sun, simple trigonometry can yield the distance. The Hipparcos satellite was launched in 1989 to create a comprehensive catalog of trigonometric parallax measurements from space. The distance quoted above is from this catalog. NOTABLE FEATURES/FACTS • William Herschel discovered Algieba’s binary nature in 1782. • Both components of Algieba have evolved beyond the main sequence. They began their lives as B-type stars, and they will end their lives as white dwarfs. • In 2010, a team including former UT astronomer Arte Hatzes discovered a planet orbiting Algieba A. The planet is nine times the mass of Jupiter and orbits the star in 1.2 years at an average distance of 1.2 AU. SUMMER SP TARGET INFORMATION MESSIER 97 (THE OWL NEBULA) BASIC INFORMATION OBJECT TYPE: Planetary Nebula CONSTELLATION: Ursa Major BEST VIEW: Early May DISCOVERY: Pierre Mechain, 1781 DISTANCE: ~2000 ly DIAMETER: 1.8 ly APPARENT MAGNITUDE: +9.9 APPARENT DIMENSIONS: 3.3’ DISTANCE DETERMINATION The distances to most planetary nebulae are very poorly known. A variety of methods can be used, providing mixed results. In many cases, astronomers resort to statistical methods to estimate the distances to planetary nebulae. Although we don’t have accurate distances for most of the planetary nebulae in the Milky Way, we do know exactly how far away the Large Magellanic Cloud is.

  • Making a Sky Atlas
    Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it.

  • The Lagoon Nebula and Its Vicinity

Tothill Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA and School of Physics, University of Exeter, Stocker Road, Exeter, EX4 4QL, UK Marc Gagn´e Department of Geology and Astronomy, West Chester University, West Chester, PA 19383, USA B. Stecklum Thuringer¨ Landessternwarte Tautenburg, Sternwarte 5, D-07778 Tautenburg, Germany M. A. Kenworthy Steward Observatory, University of Arizona, 933 N. Cherry Avenue, Tucson, AZ 85721, USA Abstract. The Lagoon Nebula is an HII region in the Sagittarius Arm, about 1.3 kpc away, associated with the young (1–3 Myr) open cluster NGC6530, which contains several O stars and several dozen B stars. Lower-mass cluster members, detected by X-ray and Hα emission, and by near-IR excess, number more than a thousand. Myr-old star formation is traced by the optically-visible HII region and cluster; observations of infrared and submillimetre-wave emission, and of optical emission features, indicate ongoing star formation in several locations across the Lagoon. The most prominent of these are the Hourglass Nebula and M8 E. Submillimetre-wave observations also reveal many clumps of dense molecular gas, which may form the next generation of stars. The complex structure of the region has been shaped by the interaction of the underlying molecular gas with multiple massive stars and episodes of star formation. NGC6530 is the oldest component, with the newest stars found embedded in the molecular gas behindthecluster andat its southernrim.

Fantastic WR bubble, responds extremely well to OIII filter. Shell is most obvious as a crescent NW of o1 CMa, becoming fainter at NW. Brighter patch again at N to NE. At 80x under excellent conditions, the shell can be further followed from this N part down the E side back to o1 CMa, forming a closed bubble around EZ CMa. Only with 7mm exit pupil, the center appears filled and somewhat lighter than the outside of the bubble. This is not visible with 5.5mm exit pupil.

Observations were carried out during the nights of 25{27 December 2015 and 6{7 June 2017 with different long exposure times ranging from 900 s to 3600 s. These spectra provide information about the local standard of rest (LSR) velocities, the full width at half maximum (FWHM), and densities of the sources. The LSR velocities and the FWHM of the Hα emission lines were found to be in the range of {50.31 km/s to 27.57 km/s and 34.88 km/s to 44.54 km/s (mean FWHM: 37.19 km/s), respectively. The NGC 6543 (Cat's Eye Nebula) is the faintest one (75.06 R), while the NGC 1982 H II region is brightest source (38,477.3 R).

The unwelcome winds are blowing, the even more unwelcome rain and clouds are around – but the rather more welcome darker nights are beginning and a new CaDAS season is under way. Comet Garradd is in the skies, and may even become visible to the naked eye soon. Supernovae are erupting in popular galaxies – the summer's M51 has been followed by M101. And Jupiter is gradually getting about as big and bright in our skies as it ever gets. What's not to like?! (OK, sorry I mentioned the clouds …) Much of all that crops up one way or another in this month's Transit. Please make a special note of the information on page 14 about the date and place of this autumn's Thomas Wright Trophy competition, which, as ever, constitutes our October meeting.
