    • Deciphering the bipolar planetary nebula abell 14 with 3d ionization and morphological studies 

      Akras, S.; Clyne, N.; Boumis, P.; Monteiro, H.; Gonçalves, D. R.; Redman, M. P.; Williams, S. (Oxford University Press (OUP), 2016-02-23)
      Abell 14 is a poorly studied object despite being considered a born-again planetary nebula. We performed a detailed study of its 3D morphology and ionization structure using the SHAPE and MOCASSIN codes. We found that Abell ...

    • Supersonic turbulence in the cold massive core jcmt 18354���0649s��� 

      Carolan, P. B.; Khanzadyan, T.; Redman, M. P.; Thompson, M. A.; Jones, P. A.; Cunningham, M. R.; Loughnane, R. M.; Bains, I.; Keto, E. (Oxford University Press (OUP), 2009-11-21)
      An example of a cold massive core, JCMT 18354-0649S which is a possible high-mass analogue to a low-mass star-forming core, is studied. Line and continuum observations from James Clerk Maxwell Telescope, Mopra Telescope ...

    • Witnessing the emergence of a carbon star 

      Guzman-Ramirez, L.; Lagadec, E.; Wesson, R.; Zijlstra, A. A.; Muller, A.; Jones, D.; Boffin, H. M. J.; Sloan, G. C.; Redman, M. P.; Smette, A.; Karakas, A. I.; Nyman, L.-A. (Oxford University Press (OUP), 2015-05-11)
      During the late stages of their evolution, Sun-like stars bring the products of nuclear burning to the surface. Most of the carbon in the Universe is believed to originate from stars with masses up to a few solar masses. ...
