Did the Solar system form in a sequential triggered star formation event?
(2015-12-18)
The presence and abundance of the short-lived radioisotopes (SLRs) 26Al and 60Fe during the formation of the Solar system is difficult to explain unless the Sun formed in the vicinity of one or more massive star(s) that ...
Isolating signatures of major cloud-cloud collisions - II. The lifetimes of broad bridge features
(2015-12-01)
We investigate the longevity of broad bridge features in position–velocity diagrams that appear as a result of cloud–cloud collisions. Broad bridges will have a finite lifetime due to the action of feedback, conversion of ...
STARBENCH: the D-type expansion of an H II region
(2015-10-21)
STARBENCH is a project focused on benchmarking and validating different star formation and stellar feedback codes. In this first STARBENCH paper we perform a comparison study of the D-type expansion of an H II region. The ...
The modelling of feedback in star formation simulations
(2015-10-01)
I review the current state of numerical simulations of stellar feedback in the context of star formation at scales ranging from the formation of individual stars to models of galaxy formation including cosmic reionisation. ...
On the spatial distributions of stars and gas in numerical simulations of molecular clouds
(2015-08-21)
We compare the spatial distribution of stars which form in hydrodynamical simulations to the spatial distribution of the gas, using the Q -parameter. The Q-parameter enables a self-consistent comparison between the stars ...
Early evolution of embedded clusters
(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 ...
The dangers of being trigger-happy
(2015-06-21)
We examine the evidence offered for triggered star formation against the backdrop provided by recent numerical simulations of feedback from massive stars at or below giant molecular cloud sizescales. We compile a catalogue ...
The Pillars of Creation revisited with MUSE: gas kinematics and high-mass stellar feedback traced by optical spectroscopy
(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 ...
Isolating signatures of major cloud-cloud collisions using position-velocity diagrams
(2015-06-01)
Collisions between giant molecular clouds are a potential mechanism for triggering the formation of massive stars, or even super star clusters. The trouble is identifying this process observationally and distinguishing it ...
Studying the YMC population of M83: how long clusters remain embedded, their interaction with the ISM and implications for GC formation theories
(2015-05-01)
The study of young massive clusters can provide key information for the formation of globular clusters, as they are often considered analogues. A currently unanswered question in this field is how long these massive clusters ...
