X-ray emission from massive stars in CYG OB2 (2015)
Journal Article
Wright. (2015). X-ray emission from massive stars in CYG OB2. Astrophysical Journal Supplement, https://doi.org/10.1088/0067-0049/221/1/1

We report on the analysis of the Chandra-ACIS data of O, B, and WR stars in the young association Cyg OB2. X-ray spectra of 49 O-stars, 54 B-stars, and 3 WR-stars are analyzed and for the brighter sources, the epoch dependence of the X-ray fluxes is...

Classical T Tauri stars with VPHAS+ – I. H α andu-band accretion rates in the Lagoon Nebula M8 (2015)
Journal Article
Kalari, V. M., Vink, J. S., Drew, J. E., Barentsen, G., Drake, J. J., Eislöffel, J., …Wright, N. J. (2015). Classical T Tauri stars with VPHAS+ – I. H α andu-band accretion rates in the Lagoon Nebula M8. Monthly Notices of the Royal Astronomical Society, 453(1), 1026-1046. https://doi.org/10.1093/mnras/stv1676

We estimate the accretion rates of 235 Classical T Tauri star (CTTS) candidates in the Lagoon Nebula using ugri H α photometry from the VST Photometric H α survey+. Our sample consists of stars displaying H α excess, the intensity of which is used to... Read More about Classical T Tauri stars with VPHAS+ – I.

New OB star candidates in the Carina Arm around Westerlund 2 from VPHAS+ (2015)
Journal Article
Wright. (2015). New OB star candidates in the Carina Arm around Westerlund 2 from VPHAS+. Monthly Notices of the Royal Astronomical Society, 3855-3873. https://doi.org/10.1093/mnras/stv843

O and early B stars are at the apex of galactic ecology, but in the Milky Way, only a minority of them may yet have been identified. We present the results of a pilot study to select and parametrize OB star candidates in the Southern Galactic plane,...

The Massive Star Population of Cygnus OB2 (2015)
Journal Article
Wright. (2015). The Massive Star Population of Cygnus OB2. Monthly Notices of the Royal Astronomical Society, 741-760. https://doi.org/10.1093/mnras/stv323

We have compiled a significantly updated and comprehensive census of massive stars in the nearby Cygnus OB2 association by gathering and homogenizing data from across the literature. The census contains 169 primary OB stars, including 52 O-type stars... Read More about The Massive Star Population of Cygnus OB2.
