McGroarty, F., Ray, T. P., Froebrich, D.
In a previous paper (McGroarty & Ray 2004, 420, 975) we examined the environment of a number of evolved low-mass young stars, i.e. Classical T Tauri Stars, to see if they are capable of driving...

We present infrared echelle spectroscopy of three Herbig-Haro (HH) driving sources (SVS 13, B5-IRS 1 and HH 34 IRS) using Subaru-IRCS. The large diameter of the telescope and wide spectral coverage...
AO Assisted Near-IR Spectroscopy of SVS 13 and its Jet (2005)
Davis, C. J., Nisini, B., Takami, M., Smith, M. D., Whelan, E., ...
We present long-slit H- and K-band spectroscopy of the low-mass outflow source SVS 13, obtained with the adaptive-optics assisted imager-spectrometer NACO on the VLT. With a spatial resolution of <...
A Galactic Plane Relative Extinction Map from 2MASS (2005)
Froebrich, D., Ray, T. P., Murphy, G. C., Scholz, A.
We present three 14400 square degree relative extinction maps of the Galactic Plane (|b|
Classical T Tauri stars as sources of parsec-scale optical outflows (2004)
Previous studies of young stellar objects (YSOs) have uncovered a number of associated parsec-scale optical outflows, the majority of which are driven by low-mass, embedded Class I sources. Here we...
Detection of a warm molecular wind in DG Tauri (2004)
Takami, M., Chrysostomou, A., Ray, T.P., Davis, C.J., Dent, W.R., Bailey, J., ...
Whelan, E. T., Ray, T. P., Davis, C. J.
The Paschen beta (1.2822 micron) emission line found in the near-infrared spectra of T-Tauri stars (TTSs) is believed to trace the accretion of material onto the central star. We present...
Detection of a warm molecular wind in DG Tauri (2003)
Takami, M., Chrysostomou, A., Ray, T. P., Davis, C., Dent, W. R. F., Bailey, J., ...
We detect near-infrared H2 emission in DG Tau using the Infrared Camera and Spectrograph (IRCS) on the 8.2-m SUBARU telescope. The spectra obtained along the jet axis show that the centroidal...
It is now realised that outows from young stars are an essential part of the star-formation process and may even be necessary for disk accretion to occur. While the ows themselves can stretch for...

RevMexAA (Serie de Conferencias), 13, 83-89 (2002) (2002)
If we are to understand the origins of emission line jets from young stars we have to probe their immediate circumstellar environments on scales of 10 AU or less. Although this is dicult to do in the...
