Massive OB stars are critical to the ecology of galaxies and yet our knowledge of OB stars in the Milky Way, fainter than V ~ 12, remains patchy. Data from the VST Photometric Ha Survey (VPHAS+) permit the construction of the first deep catalogues of...

Physical parameters of IPHAS-selected classical Be stars: I. Determination procedure and evaluation of the results⋆ (2016)
Journal Article
Gkouvelis, L., Fabregat, J., Zorec, J., Steeghs, D., Drew, J. E., Raddi, R., …Drake, J. J. (2016). Physical parameters of IPHAS-selected classical Be stars: I. Determination procedure and evaluation of the results⋆. Astronomy & Astrophysics, 591, A140. https://doi.org/10.1051/0004-6361/201527090

We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotometric system. Our aim is to apply this procedure to a large sample of CB... Read More about Physical parameters of IPHAS-selected classical Be stars: I. Determination procedure and evaluation of the results⋆.

Mass segregation in star clusters is not energy equipartition (2016)
Journal Article
Wright. (2016). Mass segregation in star clusters is not energy equipartition. Monthly Notices of the Royal Astronomical Society, 119-123. https://doi.org/10.1093/mnrasl/slw061

Mass segregation in star clusters is often thought to indicate the onset of energy equipartition, where the most massive stars impart kinetic energy to the lower-mass stars and brown dwarfs/free floating planets. The predicted net result of this is t... Read More about Mass segregation in star clusters is not energy equipartition.

Globules and pillars in Cygnus X: I.Herschelfar-infrared imaging of the Cygnus OB2 environment⋆ (2016)
Journal Article
Schneider, N., Bontemps, S., Motte, F., Blazere, A., André, P., Anderson, L. D., …Wright, N. J. (2016). Globules and pillars in Cygnus X: I.Herschelfar-infrared imaging of the Cygnus OB2 environment⋆. Astronomy & Astrophysics, 591, Article A40. https://doi.org/10.1051/0004-6361/201628328

The radiative feedback of massive stars on molecular clouds creates pillars, globules and other features at the interface between the H II  region and molecular cloud. Optical and near-infrared observations from the ground as well as with the Hubble... Read More about Globules and pillars in Cygnus X: I.Herschelfar-infrared imaging of the Cygnus OB2 environment⋆.

Discovery of a long-lived, high-amplitude dusty infrared transient (2016)
Journal Article
Britt, C. T., Maccarone, T. J., Green, J. D., Jonker, P. G., Hynes, R. I., Torres, M. A. P., …Nelemans, G. (2016). Discovery of a long-lived, high-amplitude dusty infrared transient. Monthly Notices of the Royal Astronomical Society, 460(3), 2822-2833. https://doi.org/10.1093/mnras/stw1182

We report the detection of an infrared-selected transient which has lasted at least five years, first identified by a large mid-infrared and optical outburst from a faint X-ray source detected with the Chandra X-ray Observatory. In this paper we rule... Read More about Discovery of a long-lived, high-amplitude dusty infrared transient.

Cygnus OB2 DANCe: A high-precision proper motion study of the Cygnus OB2 association (2016)
Journal Article
Wright. (2016). Cygnus OB2 DANCe: A high-precision proper motion study of the Cygnus OB2 association. Monthly Notices of the Royal Astronomical Society, 2593 - 2610. https://doi.org/10.1093/mnras/stw1148

We present a high-precision proper motion study of 873 X-ray and spectroscopically selected stars in the massive OB association Cygnus OB2 as part of the DANCe project. These were calculated from images spanning a 15 yr baseline and have typical prec... Read More about Cygnus OB2 DANCe: A high-precision proper motion study of the Cygnus OB2 association.
