We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective temperatures hotter than the Sun, and on the other hand, to explore the Li dip and the evolution of Li at high metallicities. Methods. We present lithium abundances for 353 main sequence stars with and without planets in the Teff range 5900–7200 K. We observed 265 stars of our sample with HARPS spectrograph during different planets search programs. We observed the remaining targets with a variety of high-resolution spectrographs. -

The Radio Properties of a Complete Sample of Bright Galaxies
Aust. J. Phys., 1982,35,321-50 The Radio Properties of a Complete Sample of Bright Galaxies J. I. Harnett School of Physics, University of Sydney, Sydney, N.S.W. 2006. Abstract Results are given for the radio continuum properties of an optically complete sample of 294 bright galaxies, 147 of which have been detected. Data were obtained with the 408 MHz Molonglo Radio Telescope. The radio luminosity functions for all galaxies and for spiral galaxies alone are derived and the radio emission for different galaxy types is investigated. Spectral indices of 73 galaxies which had been detected at other frequencies were derived; the mean index of a reliable subsample is <ex) = -0,71. 1. Introduction There have been many extensive surveys of continuum radio emission from bright galaxies. The earliest comprehensive survey of high sensitivity was that of Cameron (1971a, 1971b) using the Molonglo Cross Radio Telescope at 408 MHz. Cameron observed two optically complete samples south of b = + 18° and defined the radio luminosity function with reasonable statistics at radio powers of ~ 1022 W HZ-I. In the past decade the optical properties of galaxies have been revised so that the selection of an optically complete sample is more reliable. In addition, between 1970 and 1978 the sensitivity of the 408 MHz Molonglo Cross was improved by more than a magnitude, permitting more detections and more accurate measurements of weak' radio emission. Before observations at 408 MHz with the Molonglo Cross ceased in 1978, a new survey was made to improve Cameron's results and provide the best possible data base for subsequent investigations at different frequencies. -

We find that the original members of the NGC 3109 association, together with the recently discovered and adjacent dwarf irregular Leo P, form a very tight and elongated configuration in space. All these galaxies lie within ∼100 kpc of a line that is '1070 kpc long, from one extreme (NGC 3109) to the other (Leo P), and they show a gradient in the Local Group standard of rest velocity with a total amplitude of 43 km s−1 Mpc−1, and a rms scatter of just 16.8 km s−1. It is shown that the reported configuration is exceptional given the known dwarf galaxies in the Local Group and its surroundings. -

1. Introduction 2. the Accordant Group Members
THE ASTROPHYSICAL JOURNAL, 474:74È83, 1997 January 1 ( 1997. The American Astronomical Society. All rights reserved. Printed in U.S.A. DISCORDANT ARGUMENTS ON COMPACT GROUPS HALTON ARP Max-Planck-Institut fu r Astrophysik, Karl-Schwarzschild-Strasse 1, 85740 Garching, Germany Received 1995 December 8; accepted 1996 July 17 ABSTRACT Much print has been dedicated to explaining discordant redshifts in compact groups as unrelated background galaxies. But no one has analyzed the accordant galaxies. It is shown here that when there is a brightest galaxy in the group, the remainder with di†erences of less than 1000 km s~1 are systemati- cally redshifted. This is the same result as obtained in all other well-deÐned groups and demonstrates again an increasing intrinsic redshift with fainter luminosity. DeÐning discordant redshifts as 1000 km s~1 or greater than the brightest galaxy, it is shown that 76 out of 345, or 22% are discordant, reaching excesses of up to 23,000 km s~1. This large percentage cannot be explained by background contamination because the number of discordances would be expected to increase rapidly with larger excesses, exactly opposite to what is observed in compact groups. HicksonÏs logarithmic intensity image of the NGC 1199 group conÐrms earlier direct evidence from Arp that a peculiar, compact object of 13,300 km s~1 redshift is silhouetted in front of the 2705 km s~1 central galaxy. Subject headings: galaxies: clusters: general È galaxies: distances and redshifts 1. INTRODUCTION 2. THE ACCORDANT GROUP MEMBERS Accordant members are here deÐned as galaxies with When redshifts began to be measured in the nearest, *cz \ 1000 km s~1 di†erence from the redshift of the densest groups of galaxies, it quickly became evident that brightest galaxy in the group. -

Craig Wheeler, Supervisor Inger Jørgensen Karl Gebhardt Chris Sneden Ralf Bender Galaxy Evolution: The Relationship Between Structure, Star Formation, and Environment by Marcel Peter Bergmann, B.S., M.A. DISSERTATION Presented to the Faculty of the Graduate School of The University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY THE UNIVERSITY OF TEXAS AT AUSTIN December 2002 Dedicated to Peter, Margot, Marianne, and Ernest Bergmann who taught me the equal importance of hard work and creativity in science, and in life. Acknowledgments I enjoyed my time during grad school, and have many people to thank. First and foremost, I am deeply grateful to my advisors Inger Jørgensen and Gary Hill for mentoring me in the ways of research and the forging of a scientific career. Their never-wavering support was invaluable as I struggled through the process of writing papers and this dissertation. I would also like to thank Craig Wheeler, my faculty supervisor, for many good suggestions regarding writing and the job hunt. Karl Gebhardt, though not formally one of my supervisors, has been a great teacher and collaborator since his arrival in Texas two years ago. I look forward to many years of continued collaboration with all of these great scientists. I also discovered during graduate school that I am a social person, and rely greatly on social interaction with others to maintain my spirit and sanity. -

The Hα survey atlas and catalog J. Rossa ??1,2 and R.–J. Dettmar1 1 Astronomisches Institut, Ruhr–Universit¨at Bochum, D–44780 Bochum, Germany e-mail: [email protected], [email protected] 2 Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, MD 21218, U.S.A. (present address) Received 14 February 2003 / Accepted 6 May 2003 Abstract. In this second paper on the investigation of extraplanar diffuse ionized gas in nearby edge–on spiral galaxies we present the actual results of the individual galaxies of our Hα imaging survey. A grand total of 74 galaxies have been studied, including the 9 galaxies of a recently studied sub–sample (Rossa & Dettmar 2000). 40.5% of all studied galaxies reveal extraplanar diffuse ionized gas, whereas in 59.5% of the survey galaxies no extraplanar diffuse ionized gas could be detected. The average distances of this extended emission above the galactic midplane range from 1–2 kpc, while individual filaments in a few galaxies reach distances of up to |z| ∼ 6 kpc. In several cases a pervasive layer of ionized gas was detected, similar to the Reynolds layer in our Milky Way, while other galaxies reveal only extended emission locally. The morphology of the diffuse ionized gas is discussed for each galaxy and is compared with observations of other important ISM constituents in the context of the disk–halo connection, in those cases where published results were available. -
