    • Chasing discs around O-type (proto)stars : Evidence from ALMA observations 

      Cesaroni, R.; Sánchez-Monge, A.; Beltrán, M.~T.; Johnston, K. G.; Maud, L. T.; Moscadelli, Luca; Mottram, J.~C.; Ahmadi, A.; Allen, V.; Beuther, H.; Csengeri, T.; Etoka, S.; Fuller, G. A.; Galli, D.; Galván-Madrid, R.; Goddi, C.; Henning, Th; Hoare, M.G.; Klaassen, P.~D.; Kuiper, R.; Kumar, M. S.N.; Lumsden, S.; Peters, T.J.; Rivilla, Victor M.; Schilke, P.; Testi, L.; van der Tak, F.F.S.; Vig, S.; Walmsley, C.M.; Zinnecker, H. (2017-06-13)
      Context. Circumstellar discs around massive stars could mediate the accretion onto the star from the infalling envelope, and could minimize the effects of radiation pressure. Despite such a crucial role, only a few convincing ...

    • Cloud disruption via ionized feedback: tracing pillar dynamics in Vulpecula 

      Klaassen, P.~D.; Mottram, J.~C.; Juhasz, A.; Dale, James (2014-06-11)
      The major physical processes responsible for shaping and sculpting pillars in the clouds surrounding massive stars (i.e. the ‘Pillars of Creation’) are now being robustly incorporated into models quantifying the ionizing ...

    • Connecting the dots: a correlation between ionizing radiation and cloud mass-loss rate traced by optical integral field spectroscopy 

      McLeod, A.~F.; Gritschneder, M.; Dale, James; Ginsburg, A.; Klaassen, P.~D.; Mottram, J.~C.; Preibisch, T.; Ramsay, S.; Reiter, M.; Testi, L. (2016-11-11)
      We present an analysis of the effect of feedback from O- and B-type stars with data from the integral field spectrograph Multi Unit Spectroscopic Explorer (MUSE) mounted on the Very Large Telescope of pillar-like structures ...
