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
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
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

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.
