A 3D photoionization model of the extreme planetary nebula NGC 6302
Wright, N.J.; Barlow, M.J.; Ercolano, B.; Rauch, T. (2011-11-01)We present a 3D photoionization model of the planetary nebula NGC 6302, one of the most complex and enigmatic objects of its kind. Its highly bipolar geometry and dense massive disc, coupled with the very wide range of ... -
Before the first supernova: combined effects of H II regions and winds on molecular clouds
Ngoumou, J.; Ercolano, B.; Bonnell, I.~A.; Dale, James (2014-07-21)We model the combined effects of photoionization and momentum-driven winds from O-stars on molecular clouds spanning a parameter space of initial conditions. The dynamical effects of the winds are very modest. However, in ... -
Detection of a Massive Dust Shell around the Type II Supernova SN 2002hh
Barlow, M.J.; Sugerman, B.E.K.; Fabbri, J.; Meixner, M.; Fisher, R.S.; Bowey, J.; Panagia, N.; Ercolano, B.; Clayton, G.; Cohen, M.; Gledhill, T.; Gordon, K.; Tielens, A.G.G.M.; Zijlstra, A.A. (2005) -
Early evolution of embedded clusters
Ercolano, B.; Bonnell, I.~A.; Dale, James (2015-07-21)We examine the combined effects of winds and photoionizing radiation from O-type stars on embedded stellar clusters formed in model turbulent molecular clouds covering a range of masses and radii. We find that feedback is ... -
Ionizing feedback from massive stars in massive clusters - II. Disruption of bound clusters by photoionization
Ercolano, B.; Bonnell, I.~A.; Dale, James (2012-07-21)We present a smoothed particle hydrodynamics parameter study of the dynamical effect of photoionization from O-type stars on star-forming clouds of a range of masses and sizes during the time window before supernovae ... -
Massive stars in massive clusters - IV. Disruption of clouds by momentum-driven winds
Ngoumou, J.; Ercolano, B.; Bonnell, I.~A.; Dale, James (2013-12-21)We examine the effect of momentum-driven OB-star stellar winds on a parameter space of simulated turbulent giant molecular clouds using smoothed particle hydrodynamic simulations. By comparison with identical simulations ... -
Massive-star supernovae as major dust factories
Sugerman, B.E.K.; Ercolano, B.; Barlow, M.J.; Tielens, A.G.G.M.; Clayton, G.; Zijlstra, A.A.; Meixner, M.; Speck, A.; Gledhill, T. (2006) -
Observing gas and dust in simulations of star formation with Monte Carlo radiation transport on Voronoi meshes
Hubber, D.~A.; Ercolano, B.; Dale, James (2016-02-11)Ionizing feedback from massive stars dramatically affects the interstellar medium local to star-forming regions. Numerical simulations are now starting to include enough complexity to produce morphologies and gas properties ... -
The Pillars of Creation revisited with MUSE: gas kinematics and high-mass stellar feedback traced by optical spectroscopy
McLeod, A.~F.; Ginsburg, A.; Ercolano, B.; Gritschneder, M.; Ramsay, S.; Testi, L.; Dale, James (2015-06-11)Integral field unit (IFU) data of the iconic Pillars of Creation in M16 are presented. The ionization structure of the pillars was studied in great detail over almost the entire visible wavelength range, and maps of the ... -
Primordial mass segregation in simulations of star formation?
Parker, R.~J.; Ercolano, B.; Dale, James (2015-02-01)We take the end result of smoothed particle hydrodynamics (SPH) simulations of star formation which include feedback from photoionization and stellar winds and evolve them for a further 10 Myr using N-body simulations. We ... -
Protoplanetary disc evolution affected by star-disc interactions in young stellar clusters
Rosotti, G.~P.; de Juan Ovelar, M.; Hubber, D.~A.; Kruijssen, J.~M.~D.; Ercolano, B.; Walch, S.; Dale, James (2014-07-01)Most stars form in a clustered environment. Therefore, it is important to assess how this environment influences the evolution of protoplanetary discs around young stars. In turn, this affects their ability to produce ... -
Synthetic observations of simulated Pillars of Creation
Ercolano, B.; Gritschneder, M.; Westmoquette, M.; Dale, James (2012-02-11)We present synthetic observations of star-forming interstellar medium structures obtained by hydrodynamic calculations of a turbulent box under the influence of an ionizing radiation field. The morphological appearance of ... -
Turbulence in giant molecular clouds: the effect of photoionization feedback
Boneberg, D.~M.; Girichidis, P.; Ercolano, B.; Dale, James (2015-02-21)Giant molecular clouds (GMCs) are observed to be turbulent, but theory shows that without a driving mechanism turbulence should quickly decay. The question arises by which mechanisms turbulence is driven or sustained. It ...
