      Aims. The determination of reliable distances to planetary nebulae (PNe) is a major difficulty in the study of this class of objects in the Galaxy. The availability of new photometric surveys such as IPHAS (the INT/WFC ...

    • An IPHAS-based search for accreting very low-mass objects using VO tools 

      Valdivielso, L.; Martin, E.L.; Bouy, H.; Solano, E.; Drew, J.E.; Greimel, R.; Gutierrez, R.; Unruh, Y.C.; Vink, J.S. (2009)
      Context. The main goal of this paper is to prove that accreting very low-mass stars and brown dwarfs can be identified in IPHAS, an H emission survey of the northern Milky Way. Full exploitation of the IPHAS database and ...

    • The IPHAS-POSS-I proper motion survey of the Galactic plane 

      Deacon, Niall; Groot, P.; Drew, J.E.; Greimel, R.; Hambly, N.C.; Irwin, M.J.; Aungwerojwit, A.; Drake, J.; Steeghs, D. (2009)
      We present a proper motion survey of the Galactic plane, using Isaac Newton Telescope (INT) Photometric Hα Survey (IPHAS) data and Palomar Sky Survey (POSS)-I Schmidt plate data as a first epoch, that probes down to proper ...

    • IR Imaging Polarimetry of the Nuclear Regions of CEN A 

      Bailey, J.; Hough, J.; Chrysostomou, A. (Astronomical Society of the Pacific, 1994)
      Aperture polarimetry of the nucleus of Cen A (Bailey et al. 1986) revealed a very red polarized source present in the K and L bands which was interpreted as a blazar type nucleus. To study this region in more detail we ...

    • IR imaging surveys of AGB stars in the Magellanic Clouds 

      Cioni, M-R.L. (2010)
      AGB stars are ideal IR targets because they are cool and bright. Most of them escaped detection in optical or shallow IR surveys in the eighties contributing to the puzzling missing number of AGB stars with respect to ...

    • IR imaging surveys of AGB stars in the Magellanic Clouds 

      Cioni, M-R.L. (European Astronomical Society, 2010)
      AGB stars are ideal IR targets because they are cool and bright. Most of them escaped detection in optical or shallow IR surveys in the eighties contributing to the puzzling missing number of AGB stars with respect to ...

    • IR photometry and polarimetry of 2A0311−227 

      Bailey, J.; Hough, J.; Axon, D.J. (1980)
      The X-ray source 2A0311 − 227 has recently been identified with a star whose spectrum and polarization properties show it to be an AM Herculis type binary. These binaries are thought to consist of a synchronously rotating ...

    • Iris Murdoch and the Borders of Analytic Philosophy 

      Milligan, Tony (2012-06)
      Iris Murdoch's philosophical texts depart significantly from familiar analytic discursive norms. (Such as the norms concerning argument structure and the minimization of rhetoric.) This may lead us to adopt one of two ...

    • Iris Murdoch's Mortal Asymmetry 

      Milligan, Tony (2007)
      Iris Murdoch holds that the best sort of life is a figurative death of the self. This figurative death is informed by an acceptance of real mortality. A recognition of mortality is supposed to help redirect our attention ...
