We present comprehensive models for the Herbig Ae stars MWC275 and AB Aur that aim to explain their spectral energy distribution (from UV to millimeter) and long baseline interferometry (from...
Tannirkulam, A., Monnier, J. D., Millan-Gabet, R., Harries, T. J., Pedretti, E., Brummelaar, T. A. Ten, ...
Using the longest optical-interferometeric baselines currently available, we have detected strong near-infrared (NIR) emission from inside the dust-destruction radius of Herbig Ae stars MWC275 and AB...
Magnetospheric accretion on the T Tauri star BP Tauri (2008)
Donati, J. F., Jardine, M. M., Gregory, S. G., Petit, P., Paletou, F., Bouvier, J., ...
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisation signatures in...
The Inner Rim of YSO Disks: Effects of dust grain evolution (2007)
Tannirkulam, A., Harries, T. J., Monnier, J. D.
Dust-grain growth and settling are the first steps towards planet formation. An understanding of dust physics is therefore integral to a complete theory of the planet formation process. In this...
Star formation in Perseus: II. SEDs, classification and lifetimes (2006)
Hatchell, J., Fuller, G. A., Richer, J. S., Harries, T. J., Ladd, E. F.
Working with the submillimetre continuum map of the Perseus molecular cloud (Hatchell et al. 2005), we aimed to determine the evolutionary stage of each submm core in Perseus, and investigate the...
The Keck Aperture Masking Experiment: Near-Infrared Sizes of Dusty Wolf-Rayet Stars (2006)
Monnier, J. D., Tuthill, P. G., Danchi, W. C., Murphy, N., Harries, T. J.
We report the results of a high angular resolution near-infrared survey of dusty Wolf-Rayet stars using the Keck-1 Telescope, including new multi-wavelength images of the pinwheel nebulae WR 98a, WR...
Magnetospheric Accretion in Classical T Tauri Stars (2006)
Bouvier, J., Alencar, S. H. P., Harries, T. J., Johns-Krull, C. M., Romanova, M. M.
The inner 0.1 AU around accreting T Tauri stars hold clues to many physical processes that characterize the early evolution of solar-type stars. The accretion-ejection connection takes place at least...
Spectroscopic study of the long-period dust-producing WC7pd+O9 binary HD192641 (2005)
Lefevre, L., Marchenko, S. V., Lepine, S., Moffat, A. F. J., Acker, A., Harries, T. J., ...
We present the results of an optical spectroscopic study of the massive Wolf-Rayet binary WR137. These data cover the dust-formation maximum in 1997. Combining all available measurements of radial...
Linear Spectropolarimetry of Young and Other Emission Line Stars. (2005)

Hilditch, R. W., Howarth, I. D., Harries, T. J.
We have conducted a programme to determine the fundamental parameters of a substantial number of eclipsing binaries of spectral types O and B in the Small Magellanic Cloud. New spectroscopic data,...
A 2dF survey of the Small Magellanic Cloud (2004)
Evans, C. J., Howarth, I. D., Irwin, M. J., Burnley, A. W., Harries, T. J.
We present a catalogue of new spectral types for hot, luminous stars in the Small Magellanic Cloud. The catalogue contains 4161 objects, giving an order of magnitude increase in the number of SMC...
Linear line polarimetry modelling of pre-main sequence stars (2004)
Vink, Jorick S., Drew, J. E., Harries, T. J., Oudmaijer, R. D.
