The 2008 Outburst in the Young Stellar System Z CMa: The First Detection of Twin Jets

Redman, Matt P. (2010)

The Z CMa binary is understood to undergo both FU Orionis (FUOR) and EX Orionis (EXOR) type outbursts. While the SE component has been spectro- scopically identified as an FUOR, the NW component, a Herbig Be star, is the ...
CO abundances in a protostellar cloud: freeze-out and desorption in the envelope and outflow of L483

Redman, Matt P. (2007)

CO isotopes are able to probe the different components in protostellar clouds. These components, core, envelope and outflow have distinct physical conditions and sometimes more than one component contributes to the observed ...
Deep optical observations of the interaction of the SS 433 microquasar jet with the W 50 radio continuum shell

Redman, Matt P. (2007)

Four mosaics of deep, continuum-subtracted, CCD images have been obtained over the extensive galactic radio continuum shell, W 50, which surrounds the remarkable stellar system SS 433. Two of these mosaics in the Halpha+[N ...
A high-speed bi-polar outflow from the archetypical pulsating star Mira A

Redman, Matt P. (2009)

Optical images and high-dispersion spectra have been obtained of the ejected material surrounding the pulsating AGB star Mira A. The two streams of knots on either side of the star, found in far ultra-viollet (FUV) GALEX ...
A search for CO+ in planetary nebulae

Redman, Matt P. (2007)

We have carried out a systematic search for the molecular ion CO+ in a sample of 8 protoplanetary and planetary nebulae in order to determine the origin of the unexpectedly strong HCO+ emission previously detected in these ...
Supersonic turbulence in the cold massive core JCMT 18354-0649S

Redman, Matt P. (2009)

An example of a cold massive core, JCMT 18354-0649S, a possible high mass analogue to a low mass star forming core is studied. Line and continuum observations from JCMT, Mopra Telescope and Spitzer are presented and modelled ...
VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula)

Redman, Matt P. (2007)

Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots ...
