H I Deficiency in Groups : What Can We Learn from Eridanus ?
Bull. Astr. Soc. India (2004) 32, 239{245 H i de¯ciency in groups : what can we learn from Eridanus ? A. Omar¤y Raman Research Institute, Sadashivanagar, Bangalore 560 080, India Received 14 July 2004; accepted 24 August 2004 Abstract. The H i content of the Eridanus group of galaxies is studied using the GMRT observations and the HIPASS data. A signi¯cant H i de¯ciency up to a factor of 2 ¡ 3 is observed in galaxies in the Eridanus group. The de¯ciency is found to be directly correlated with the projected galaxy density and inversely correlated with the line-of-sight radial velocity. It is suggested that the H i de¯ciency is due to tidal interactions. An important implication is that signi¯cant evolution of galaxies can take place in a group environment. Keywords : galaxies: ISM { galaxies: interactions { galaxies: kinematics and dynamics { galaxies: evolution { galaxies: clusters: individual: Eridanus group { radio lines: galaxies 1. Introduction Spiral galaxies in the cores of clusters are known to be H i de¯cient compared to their ¯eld counterparts (Davies and Lewis 1973, Giovanelli and Haynes 1985, Cayatte et al. 1990, Bravo-Alfaro et al. 2000). Several gas-removal mechanisms have been proposed to explain the H i de¯ciency in cluster galaxies. There are convincing results from both the simulations and the observations that ram-pressure stripping can be active in galaxies which have crossed the high ICM (Intra Cluster Medium) density region in the cores of clusters (Vollmer et al. 2001, van Gorkom 2003). However, it is not clear that all H i de¯cient galaxies have crossed the core. -

(B. 1948) Kamada Kōji Is Known for His Mastery of the Difficult Tenmoku
KAMADA KŌJI (b. 1948) Kamada Kōji is known for his mastery of the difficult tenmoku (rabbit’s hair) glaze, a technique that originated in 10th century Song Dynasty China and entered Japan during the Muromachi period two centuries later. Kamada has revitalized the technique by applying the traditional glaze to his modernized, but still functional, teaware that challenge the concepts of balance and presence. His works serve as an updated canvas for these established glaze techniques, allowing form and glaze to beautifully complement one another. 1948 Born in Kyoto 1968 Trained in Gojōzaka with Shimizu Tadashi 1971 Graduated from Kyoto Ceramics Training School, became an instructor Began his study of tenmoku glazes 1973 Entered the 2nd Japan Craft Association, Kinki District 1976 Became an official member of the Japan Craft Society 1977 Resigned as instructor for the Kyoto prefectural government and began concentrating exclusively on creating ceramics 1982 With the closing of the public Gojōzaka kiln, he acquired his own gas kiln 1988 Studied under National Living Treasure, Shimizu Uichi 1990 Became an official member of Japan Sencha (Tea) Craft Association 2000 Juror for Nihon dentō kogeiten (Japan Traditional Crafts Exhibition) Awards: 1987 Kyoto Board of Education Chairperson's Award, the 16th Japan Craft Association Exhibition Kinki District Selected Solo Exhibitions: 1978 Osaka Central Gallery (also '79 and '80) 1980 Takashimaya Art Gallery, Kyoto (eight more shows through ‘03, then ‘13) 1984 Takashimaya Art Gallery, Nihonbashi, Tokyo -
The Search for Exomoons and the Characterization of Exoplanet Atmospheres
Corso di Laurea Specialistica in Astronomia e Astrofisica The search for exomoons and the characterization of exoplanet atmospheres Relatore interno : dott. Alessandro Melchiorri Relatore esterno : dott.ssa Giovanna Tinetti Candidato: Giammarco Campanella Anno Accademico 2008/2009 The search for exomoons and the characterization of exoplanet atmospheres Giammarco Campanella Dipartimento di Fisica Università degli studi di Roma “La Sapienza” Associate at Department of Physics & Astronomy University College London A thesis submitted for the MSc Degree in Astronomy and Astrophysics September 4th, 2009 Università degli Studi di Roma ―La Sapienza‖ Abstract THE SEARCH FOR EXOMOONS AND THE CHARACTERIZATION OF EXOPLANET ATMOSPHERES by Giammarco Campanella Since planets were first discovered outside our own Solar System in 1992 (around a pulsar) and in 1995 (around a main sequence star), extrasolar planet studies have become one of the most dynamic research fields in astronomy. Our knowledge of extrasolar planets has grown exponentially, from our understanding of their formation and evolution to the development of different methods to detect them. Now that more than 370 exoplanets have been discovered, focus has moved from finding planets to characterise these alien worlds. As well as detecting the atmospheres of these exoplanets, part of the characterisation process undoubtedly involves the search for extrasolar moons. The structure of the thesis is as follows. In Chapter 1 an historical background is provided and some general aspects about ongoing situation in the research field of extrasolar planets are shown. In Chapter 2, various detection techniques such as radial velocity, microlensing, astrometry, circumstellar disks, pulsar timing and magnetospheric emission are described. A special emphasis is given to the transit photometry technique and to the two already operational transit space missions, CoRoT and Kepler. -
The Night Sky December
The Night Sky December Equipment you will need Because of the darkness of our forest locations, you can see many wonders of the night skies with your naked eye, although your eyes will Boötes need a good 20 minutes to adjust to the darkness. Any bright lights, such as that from your torch, will set them back again. You can reduce this effect by putting a red filter on your torch. Equipment worth investing in includes: Lynx • Binoculars – cheaper and easier to carry than a telescope. Look for ones with glass lenses. • Camera – to capture that fantastic star scene forever • Tripod – essential for use with your camera • Telescope – worth investing in for the really committed stargazer • Google Skymaps – a superb free app, available for Android and Delphinius iPhone. You point your phone towards the sky and it shows you the constellations and identifies the stars using inbuilt GPS Lepus Getting started – your first 5 constellations to spot • Ursa Major (the Big Dipper) has been used by sailors since ancient times to locate the fixed-point Pole Star and navigate home • Leo (the lion) is it a lion, as the Greeks decided? Or is it K9 from Doctor Who? • Cassiopeia (the queen of Aethiopia) is one of the easiest constellations to locate and looks like a huge W, almost directly overhead • Cepheus (the king of Aethiopia) is one of 48 constellations Eridanus identified by 2nd century astronomer Ptolemy. Imagine a child’s drawing of a house, complete with roof • Orion (the hunter), with belt and sword, is perhaps the most famous constellation – and one of the few that actually bears some slight resemblance to its namesake Stargazing facts for kids • You can see the International Space Station without using binoculars, and you can track it moving across the sky • The sun is 300,000 times bigger than earth and 93 million miles Boötes Lynx Delphinus Lepus Eridanus away. -
Dynamical Stability of the Inner Belt Around Epsilon Eridani
A&A 499, L13–L16 (2009) Astronomy DOI: 10.1051/0004-6361/200811609 & c ESO 2009 Astrophysics Letter to the Editor Dynamical stability of the inner belt around Epsilon Eridani M. Brogi1, F. Marzari2, and P. Paolicchi1 1 University of Pisa, Department of Physics, Largo Pontecorvo 3, 56127 Pisa, Italy e-mail: [email protected]; [email protected] 2 University of Padua, Department of Physics, via Marzolo 8, 35131 Padua, Italy e-mail: [email protected] Received 31 December 2008 / Accepted 17 April 2009 ABSTRACT Context. Recent observations with Spitzer and the Caltech Submillimeter Observatory have discovered the presence of a dust belt at about 3 AU, internal to the orbit of known exoplanet Eri b. Aims. We investigate via numerical simulations the dynamical stability of a putative belt of minor bodies, as the collisional source of the observed dust ring. This belt must be located inside the orbit of the planet, since any external source would be ineffective in resupplying the inner dust band. Methods. We explore the long-term behaviour of the minor bodies of the belt and how their lifetime depends on the orbital parameters of the planet, in particular for reaching a steady state. Results. Our computations show that for an eccentricity of Eri b equal or higher than 0.15, the source belt is severely depleted of its original mass and substantially reduced in width. A “dynamical” limit of 0.10 comes out, which is inconsistent with the first estimate of the planet eccentricity (0.70 ± 0.04), while the alternate value (0.23 ± 0.2) can be consistent within the uncertainties. -

Kraak Porcelain
Large Dishes from Jingdezhen and Longquan around the World Dr Eva Ströber Keramiekmuseum Princessehof, NL © Eva Ströber 2010 Cultures of Ceramics in Global History, 1300-1800 University of Warwick, 22-24 April 2010 Global History Arts & Humanities & Culture Centre Research Council http://www2.warwick.ac.uk/fac/arts/history/ghcc/research/globalporcelain/conference Large Dishes from Jingdezhen and Longquan around the World The talk will be about the huge success of a type of Chinese porcelain the Chinese themselves had indeed no use for: large serving dishes, large meaning more than 35 cm in diam. The most common blue and white type was made in Jingdezhen, the Celadon type in the Longquan kilns in Southern Zhejiang and Northern Fujian. Another type of large dishes, the Zhangzhou type, was produced in the kilns of Zhangzhou, Fujian. The focus will be on three markets these oversized dishes were made for: the Muslim markets of the Middle East, particularly Persia, Turkey and the Mughal empire, SE Asia including what is now Indonesia, and Japan. By miniatures, drawings, paintings or old photographs it will be illustrated, how these large Chinese dishes were used in a non Chinese social and cultural context. The Chinese Bowl The Chinese themselves, as can be seen on the famous painting of a literati gathering from the Song – dynasty of the 12th century, dined from rather small sized tableware. The custom to eat from small dishes and particularly from bowls started in the Song dynasty and spread to many countries in SE Asia. It has not changed even to this very day. -
A Guide to Star Names, Pronunciations, and Related Constellations
Astronomy Club of Asheville 3 Feb. 2020 version Page 1 of 8 A Guide to Star Names, Pronunciations, and Related Constellations Proper Star Names: There are over 300 proper star names that are used and accepted worldwide today -- and approved by the International Astronomical Union. Most of them come from the ancient Arabic cultures, but there are many star names in common use from the Greek, the Roman, European, and other cultures as well. On the pages below you will find an alphabetical list of many, but not all, of the proper star names, their pronunciations, and related constellations. Find a list of star names by constellation at this web link. Find another list of common star names at this web link. Star Catalogs that are Currently Used by Astronomers 1. Bayer Catalog: This first widely recognized star catalog was published by German astronomer Johann Bayer in 1603. This list of naked-eye stars indexes the stars in each constellation, using the letters of the Greek alphabet, followed by the genitive form of its parent constellation's Latin name, e.g., alpha Orionis. Typically, the brightest star in each constellation received the first Greek letter (alpha), the second brightest star the second letter (beta), and on-and-on. But you will often notice that the Bayer sequencing of the bright stars in the constellations is not true to what we see and know today about their apparent brightness. Original errors in the brightness estimates, along with the brightness variability of the stars (like Betelgeuse in Orion), have caused the Bayer sequencing not to match the stellar brightness that we observe today. -
