Journal Article
Guarcello, M. G., Drake, J. J., Wright, N. J., García-Alvarez, D., & Kraemer, K. E. (in press). ACCRETION AND OUTFLOW IN THE PROPLYD-LIKE OBJECTS NEAR CYGNUS OB2. Astrophysical Journal, 793(1), Article 56. https://doi.org/10.1088/0004-637x/793/1/56

Cygnus OB2 is the most massive association within 2 kpc from the Sun, hosting hundreds of massive stars, thousands of young low mass members, and some sights of active star formation in the surrounding cloud. Recently, 10 photoevaporating proplyd-lik... Read More about ACCRETION AND OUTFLOW IN THE PROPLYD-LIKE OBJECTS NEAR CYGNUS OB2.

BURN OUT OR FADE AWAY? ON THE X-RAY AND MAGNETIC DEATH OF INTERMEDIATE MASS STARS (2014)
Journal Article

The nature of the mechanisms apparently driving X-rays from intermediate mass stars lacking strong convection zones or massive winds remains poorly understood, and the possible role of hidden, lower mass close companions is still unclear. A 20 ks Cha... Read More about BURN OUT OR FADE AWAY? ON THE X-RAY AND MAGNETIC DEATH OF INTERMEDIATE MASS STARS.

Extreme infrared variables from UKIDSS – I. A concentration in star-forming regions (2014)
Journal Article
Contreras Peña, C., Lucas, P. W., Froebrich, D., Kumar, M. S. N., Goldstein, J., Drew, J. E., …Wright, N. J. (2014). Extreme infrared variables from UKIDSS – I. A concentration in star-forming regions. Monthly Notices of the Royal Astronomical Society, 439(2), 1829-1854. https://doi.org/10.1093/mnras/stu063

We present initial results of the first panoramic search for high-amplitude near-infrared variability in the Galactic plane. We analyse the widely separated two-epoch K-band photometry in the fifth and seventh data releases of the UKIDSS Galactic pla... Read More about Extreme infrared variables from UKIDSS – I.

Constraints on massive star formation: Cygnus OB2 was always an association (2013)
Journal Article
Wright, N. J., Parker, R. J., Goodwin, S. P., & Drake, J. J. (2014). Constraints on massive star formation: Cygnus OB2 was always an association. Monthly Notices of the Royal Astronomical Society, 438(1), 639-646. https://doi.org/10.1093/mnras/stt2232

We examine substructure and mass segregation in the massive OB association Cygnus OB2 to better understand its initial conditions. Using a well-understood Chandra X-ray selected sample of young stars, we find that Cyg OB2 exhibits considerable physic...

THE PROTOPLANETARY DISKS IN THE NEARBY MASSIVE STAR-FORMING REGION CYGNUS OB2 (2013)
Journal Article

The formation of stars in massive clusters is one of the main modes of the star formation process. However, the study of massive star-forming regions is hampered by their typically large distances to the Sun. One exception to this is the massive star...

New Galactic supernova remnants discovered with IPHAS (2013)
Journal Article
Sabin, L., Parker, Q. A., Contreras, M. E., Olguín, L., Frew, D. J., Stupar, M., …Morris, R. A. H. (2013). New Galactic supernova remnants discovered with IPHAS. Monthly Notices of the Royal Astronomical Society, 431(1), 279-291. https://doi.org/10.1093/mnras/stt160

As part of a systematic search programme of a 10° wide strip of the northern Galactic plane, we present preliminary evidence for the discovery of four (and possibly five) new supernova remnants (SNRs). The pilot search area covered the 19–20 h right... Read More about New Galactic supernova remnants discovered with IPHAS.

First results of an Hα based search of classical Be stars in the Perseus Arm and beyond (2013)
Journal Article
Raddi, R., Drew, J. E., Fabregat, J., Steeghs, D., Wright, N. J., Sale, S. E., …Drake, J. J. (2013). First results of an Hα based search of classical Be stars in the Perseus Arm and beyond. Monthly Notices of the Royal Astronomical Society, 430(3), 2169-2187. https://doi.org/10.1093/mnras/stt038

We investigate a region of the Galactic plane, between 120° ≤ ℓ ≤ 140° and −1° ≤ b ≤ +4°, and uncover a population of moderately reddened (E(B − V) ∼ 1) classical Be stars within and beyond the Perseus and Outer Arms. 370 candidate emission-line star...

Using a new catalog of 824 solar and late-type stars with measured X-ray luminosities and rotation periods we have studied the relationship between rotation and stellar activity that is believed to be a probe of the underlying stellar dynamo. Using a... Read More about The stellar activity-rotation relationship: The stellar activity-rotation relationship.

OB Associations
Presentation / Conference
Jeffries, & Wright. OB Associations. Presented at Protostars and Planets VII

OB associations are low-density groups of young stars that are dispersing from their birth environment into the Galactic field. They are important for understanding the star formation process, early stellar evolution, the properties and distribution... Read More about OB Associations.
