Evolution of spatio-kinematic structures in star-forming regions: are Friends of Friends worth knowing? (2018)
Journal Article
Wright, N., & Parker, R. J. (2018). Evolution of spatio-kinematic structures in star-forming regions: are Friends of Friends worth knowing?. Monthly Notices of the Royal Astronomical Society, 481(2), 1679-1689. https://doi.org/10.1093/mnras/sty2372

The Friends of Friends algorithm identifies groups of objects with similar spatial and kinematic properties, and has recently been used extensively to quantify the distributions of gas and stars in young star-forming regions. We apply the Friends of... Read More about Evolution of spatio-kinematic structures in star-forming regions: are Friends of Friends worth knowing?.

A sextet of clusters in the Vela OB2 region revealed by Gaia (2018)
Journal Article
Wright. (2018). A sextet of clusters in the Vela OB2 region revealed by Gaia. Monthly Notices of the Royal Astronomical Society: Letters, https://doi.org/10.1093/mnrasl/sly144

Using Gaia DR2 data, combined with OmegaCAM ground-based optical photometry from the AD-HOC survey, and detailed Radial Velocity measurements from ESO-Gaia, we analyse in detail a 10 ×5 deg region around the Wolf-Rayet star ?2 Vel, including the prev...

The low mass population of the Vela OB2 association from Gaia (2018)
Journal Article
Armstrong, J. J., Jeffries, R. D., & Wright, N. J. (2018). The low mass population of the Vela OB2 association from Gaia. Monthly Notices of the Royal Astronomical Society: Letters, 480(1), L121–L125. https://doi.org/10.1093/mnrasl/sly137

The first Gaia Data Release presents an opportunity to characterise the low-mass population of OB associations, providing larger statistical samples and better constraints on the formation and evolution of clusters and associations. Using previously... Read More about The low mass population of the Vela OB2 association from Gaia.

Massive stars in the hinterland of the young cluster, Westerlund 2 (2018)
Journal Article
Wright. (2018). Massive stars in the hinterland of the young cluster, Westerlund 2. Monthly Notices of the Royal Astronomical Society, 2109-2124. https://doi.org/10.1093/mnras/sty1905

An unsettled question concerning the formation and distribution of massive stars is whether they must be born in massive clusters and, if found in less dense environments, whether they must have migrated there. With the advent of wide-area digital ph... Read More about Massive stars in the hinterland of the young cluster, Westerlund 2.

The Gaia-ESO Survey: a kinematical and dynamical study of four young open clusters (2018)
Journal Article
Jeffries, R., Jackson, R., & Wright, N. (2018). The Gaia-ESO Survey: a kinematical and dynamical study of four young open clusters. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/201832645

Context The origin and dynamical evolution of star clusters is an important topic in stellar astrophysics. Several models have been proposed in order to understand the formation of bound and unbound clusters and their evolution, and they can be test...

Discovery of a New Classical Nova Shell Around a Nova-like Cataclysmic Variable (2018)
Journal Article
Wright. (2018). Discovery of a New Classical Nova Shell Around a Nova-like Cataclysmic Variable. Astrophysical Journal, https://doi.org/10.3847/1538-4357/aab669

The morphology and optical spectrum of IPHASX J210204.7+471015, a nebula classified as a possible planetary nebula are, however, strikingly similar to those of AT Cnc, a classical nova shell around a dwarf nova. To investigate its true nature, we h... Read More about Discovery of a New Classical Nova Shell Around a Nova-like Cataclysmic Variable.

A new mechanical stellar wind feedback model for the Rosette Nebula (2018)
Journal Article
Wright. (2018). A new mechanical stellar wind feedback model for the Rosette Nebula. Monthly Notices of the Royal Astronomical Society, 3598-3612. https://doi.org/10.1093/mnras/sty148

The famous Rosette Nebula has an evacuated central cavity formed from the stellar winds ejected from the 2-6 million-year-old co-distant and co-moving central star cluster NGC 2244. However, with upper age estimates of less than 110,000 years, the ce... Read More about A new mechanical stellar wind feedback model for the Rosette Nebula.

A and F stars as probes of outer Galactic disc kinematics (2018)
Journal Article
Wright. (2018). A and F stars as probes of outer Galactic disc kinematics. Monthly Notices of the Royal Astronomical Society, 1680 -1695. https://doi.org/10.1093/mnras/stx3299

Previous studies of the rotation law in the outer Galactic disc have mainly used gas tracers or clump giants. Here, we explore A and F stars as alternatives: these provide a much denser sampling in the outer disc than gas tracers and have experienced...

A tale of three cities - OmegaCAM discovers multiple sequences in the color-magnitude diagram of the Orion Nebula Cluster (2017)
Journal Article

As part of the accretion discs in Ha with OmegaCAM (ADHOC) survey, we imaged a region of 12 × 8 square degrees around the Orion Nebula Cluster in r, i and Ha. Thanks to the high-quality photometry obtained, we discovered three well-separated pre-main...

The Gaia-ESO Survey: Structural and dynamical properties of the young cluster Chamaeleon I (2017)
Journal Article

Investigating the physical mechanisms driving the dynamical evolution of young star clusters is fundamental to our understanding of the star formation process and the properties of the Galactic field stars. The young (~2 Myr) and partially embedded c... Read More about The Gaia-ESO Survey: Structural and dynamical properties of the young cluster Chamaeleon I.
