Raddi, R., Drew, J. E., Steeghs, D., Wright, N. J., Drake, J. J., Barentsen, G., …Sale, S. E. (2015). A deep catalogue of classical Be stars in the direction of the Perseus Arm: spectral types and interstellar reddenings. Monthly Notices of the Royal Astronomical Society, 446(1), 274-298. https://doi.org/10.1093/mnras/stu2090

We present a catalogue of 247 photometrically and spectroscopically confirmed fainter classical Be stars (13 ≲ r ≲ 16) in the direction of the Perseus Arm of the Milky Way (−1° < b < +4°, 120° < ℓ < 140°). The catalogue consists of 181 IPHAS-selected... Read More about A deep catalogue of classical Be stars in the direction of the Perseus Arm: spectral types and interstellar reddenings.

ACCRETION AND OUTFLOW IN THE PROPLYD-LIKE OBJECTS NEAR CYGNUS OB2 (2014)
Journal Article

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
Drake, J. J., Braithwaite, J., Kashyap, V., Günther, H. M., & Wright, N. J. (in press). BURN OUT OR FADE AWAY? ON THE X-RAY AND MAGNETIC DEATH OF INTERMEDIATE MASS STARS. Astrophysical Journal, 786(2), 136. https://doi.org/10.1088/0004-637x/786/2/136

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.
