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. -

CONSTELLATION BOÖTES, the HERDSMAN Boötes Is the Cultivator Or Ploughman Who Drives the Bears, Ursa Major and Ursa Minor Around the Pole Star Polaris
CONSTELLATION BOÖTES, THE HERDSMAN Boötes is the cultivator or Ploughman who drives the Bears, Ursa Major and Ursa Minor around the Pole Star Polaris. The bears, tied to the Polar Axis, are pulling a plough behind them, tilling the heavenly fields "in order that the rotations of the heavens should never cease". It is said that Boötes invented the plough to enable mankind to better till the ground and as such, perhaps, immortalizes the transition from a nomadic life to settled agriculture in the ancient world. This pleased Ceres, the Goddess of Agriculture, so much that she asked Jupiter to place Boötes amongst the stars as a token of gratitude. Boötes was first catalogued by the Greek astronomer Ptolemy in the 2nd century and is home to Arcturus, the third individual brightest star in the night sky, after Sirius in Canis Major and Canopus in Carina constellation. It is a constellation of large extent, stretching from Draco to Virgo, nearly 50° in declination, and 30° in right ascension, and contains 85 naked-eye stars according to Argelander. The constellation exhibits better than most constellations the character assigned to it. One can readily picture to one's self the figure of a Herdsman with upraised arm driving the Greater Bear before him. FACTS, LOCATION & MAP • The neighbouring constellations are Canes Venatici, Coma Berenices, Corona Borealis, Draco, Hercules, Serpens Caput, Virgo, and Ursa Major. • Boötes has 10 stars with known planets and does not contain any Messier objects. • The brightest star in the constellation is Arcturus, Alpha Boötis, which is also the third brightest star in the night sky. -

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. -
Constellation Transformation*
Constellation Transformation* Larry Lebofsky, Nancy Lebofsky, and the NIRCam E/PO team and Michelle Higgins and the GSSoAZ STEM Team Background: The constellations in this activity were chosen because they represent animals or objects familiar to students of many ages. The stars in the illustrations are represented by circles of several sizes as they would appear on a planisphere or star chart. The largest circles in the patterns indicate the brightest star(s) in each constellation; the smallest circles indicate the dimmest stars. The circle sizes are not necessarily equivalent to the star sizes; the circle sizes represent the stars’ apparent brightness to an observer on Earth. For example, a large star (a giant or super giant) might appear dim because of its distance or cool temperature. A smaller star might be closer and hotter, making it look bright to an observer. Star colors range from red (coolest) to orange, yellow, white, and blue (hottest). Our Sun is a medium-sized star, yellow in color (medium temperature), and spherical (a ball) in shape. Even young students frequently represent the Sun as a yellow circle in their drawings — the correct shape and color for our Solar System’s star! Objectives: Students will identify common constellation patterns. They will create their own constellations using the same star patterns. Students will write a poem about the transformation (old → new constellation picture) or a short story about their newly-created constellation. Students should acknowledge the difference between an artistic representation of a star (five points, random colors) and a scientific representation of a star (a circle to represent a spherical object, larger circles for brighter stars). -
