Paschen beta emission as a tracer of outflow activity from T-Tauri stars, as compared to Optical Forbidden emission
E. T. Whelan, T. P. Ray, C. J. Davis
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 p…
A survey of SiO 5-4 emission towards outflows from low-luminosity protostellar candidates
Andy G. Gibb, John S. Richer, Claire J. Chandler +1
We have observed the SiO J=5--4 line towards a sample of 25 low-luminosity (L* < 10^3 Lsun) protostellar outflow systems. The line was detected towards 7 of the 25 sources, a detec…
A Ring Shaped Embedded Young Stellar (Proto)Cluster
M. S. Nanda Kumar, D. K. Ojha, C. J. Davis
We present sub-arcsec (FWHM ~ 0.5") J, H, K and L' images of a young stellar cluster associated with a candidate massive protostar IRAS22134+5834. The observations reveal a central…
