The Outer Envelopes of Globular Clusters. I. NGC 7089 (M2)
We present the results of a wide-field imaging survey of the periphery of the
Milky Way globular cluster NGC 7089 (M2). Data were obtained with MegaCam on
the Magellan Clay Telescope, and the Dark Energy Camera on the Blanco
Telescope. We find that M2 is embedded in a diffuse stellar envelope extending
to a radial distance of at least ( pc) -- five
times the nominal tidal radius of the cluster. The envelope appears nearly
circular in shape, has a radial density decline well described by a power law
of index , and contains approximately of the
luminosity of the entire system. While the origin of the envelope cannot be
robustly identified using the presently available data, the fact that M2 also
hosts stellar populations exhibiting a broad dispersion in the abundances of
both iron and a variety of neutron capture elements suggests that this object
might plausibly constitute the stripped nucleus of a dwarf Galaxy that was long
ago accreted and destroyed by the Milky Way.Comment: 15 pages, 12 figures, accepted for publishing in MNRA

Entry and exit as embodied career choice in professional sport
This paper was accepted for publication in the journal Journal of Vocational Behavior and the definitive published version is available at http://dx.doi.org/10.1016/j.jvb.2015.08.003The concept of an embodied career draws attention to the individual, corporally, socially, culturally and institutionally located in relationship with work. Career theories have tended to focus on psychological and social variables and measurements that narrow understanding of contexts and agency. It is thus timely to consider a more holistic approach to understanding contemporary careers as embodied processes. The paper works on three levels; first as an empirical illustration of professional sports careers as short-term careers, second as an application of Bourdieu's habitus to understand the relationship between social fields and accounts of career choice and, third in order to draw parallels with the embodied nature of work in a more general sense. Utilising empirical material from a study of elite UK professional rugby players, it is argued that understanding an embodied-career resonates with present concerns regarding career patterns of short-term contracts, which require the individual to be committed, flexible and adaptable, be prepared for exit, and yet remain immersed and dedicated to the current sphere of employment. It is proposed that this kind of immersion requires alternatives to be, temporarily at least, silenced and in this context renders the accrual of bodily capital as fit, but only temporarily fit for purpose
