      Abundances of Fe, Si, Ni, Ti, Na, Mg, Cu, Zn, Mn, Cr and Ca in the atmosphere of the K-dwarf HD 77338 are determined and discussed. HD 77338 hosts a hot Uranus-like planet and is currently the most metal-rich single star ...

    • Abundances in very metal-poor stars 

      Ryan, Sean G. (Institut d'Astrophysique et de Geophysique, 2000)
      Metal-poor stars provide information on the characteristics and chemical evolution of the halo population of the Galaxy, the first epoch of star formation and Galaxy formation (not just locally but with relevance to ...

    • Abundances of carbon-enhanced metal-poor stars as constraints on their formation 

      Hansen, C.J.; Nordström, B.; Hansen, T.T.; Kennedy, C.R.; Placco, V.M.; Beers, T.C.; Andersen, J.; Cescutti, Gabriele; Chiappini, Cristina (2016-04-01)
      Context. An increasing fraction of carbon-enhanced metal-poor (CEMP) stars is found as their iron abundance, [Fe/H], decreases below [Fe/H] =−2.0. The CEMP-s stars have the highest absolute carbon abundances, [C/H], and ...

    • Abundances of UV bright stars in globular clusters. I. ROA 5701 in omega Centauri and Barnard 29 in M 13

      Stephan's Quintet (SQ) is a system consisting of at least four interacting galaxies which is well known for its complex dynamical and star formation history. It possesses a rich intergalactic medium (IGM), where hydrogen ...

    • Abundant molecular gas in tidal dwarf galaxies: On-going galaxy formation 

      Braine, J.; Duc, P.A.; Lisenfeld, U.; Charmandaris, V.; Vallejo, O.; Leon, S.; Brinks, E. (2001-10)
      We investigate the process of galaxy formation as can be observed in the only currently forming galaxies { the so-called Tidal Dwarf Galaxies, hereafter TDGs { through observations of the molecular gas detected via its CO ...

    • Abuse of Prescription Drugs in the Context of Novel Psychoactive Substances (NPS): A Systematic Review 

      Schifano, Fabrizio; Chiappini, Stefania; Corkery, John; Guirguis, Amira (2018-04-22)
      Recently, a range of prescription and over-the-counter drugs have been reportedly used as Novel Psychoactive Substances (NPS), due to their potential for abuse resulting from their high dosage/idiosyncratic methods of ...

    • ACA [CI] observations of the starburst galaxy NGC 253 

      Krips, M.; Martín, S.; Sakamoto, K.; Aalto, S.; Bisbas, T.~G.; Bolatto, A.~D.; Downes, D.; Eckart, A.; Feruglio, C.; García-Burillo, S.; Geach, J.; Greve, T.~R.; König, S.; Matsushita, S.; Neri, R.; Offner, S.; Peck, A.~B.; Viti, S.; Wagg, J. (2016-08-01)
      Context. Carbon monoxide (CO) is widely used as a tracer of the molecular gas in almost all types of environments. However, several shortcomings of CO complicate usaging it as H2 tracer, such as its optical depth effects, ...

    • An Academic Approach to Digital Forensics 

      Angelopoulou, Olga; Vidalis, Stilianos (2015)
      Digital forensics as a field of study creates a number of challenges when it comes to the academic environment. The aim of this paper is to explore these challenges in relation to the learning and teaching theories. We ...

    • Academic dress in the University of Hertfordshire 

      Christianson, B. (University of Hertfordshire, 2006)
      In accordance with tradition, our academic dress consists of a gown, a cap, and a hood. The black gown and square cap familiar to all readers of the Beano had evolved into pretty much their present form in England by the ...
