A high-resolution radio study of the L1551 IRS 5 and L1551 NE jets
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +10
Using observations with e-MERLIN and the VLA, together with archival data from ALMA, we obtain high-resolution radio images of two binary YSOs: L1551 IRS 5 and L1551 NE, covering a…
Detection of coherent low-frequency radio bursts from weak-line TTauri stars
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +7
In recent years, thanks to new facilities such as LOFAR capable of sensitive observations, much work has been done on the detection of stellar radio emission at low frequencies. Su…
A Multi-Epoch Study of Radio Continuum Emission from MassiveProtostars
W. O. Obonyo, S. L. Lumsden, M. G. Hoare +2
We report the results of the Jansky Very Large Array (JVLA) observation of five massive protostars at 6 and 22.2 GHz. The aim of the study was to compare their current fluxes and p…
The first detection of a low-frequency turnover in nonthermal emission from the jet of a young star
Anton Feeney-Johansson, Simon J. D. Purser, Tom P. Ray +4
Radio emission in jets from young stellar objects (YSOs) in the form of nonthermal emission has been seen toward several YSOs. Thought to be synchrotron emission from strong shocks…
Measuring the ionisation fraction in a jet from a massive protostar
R. Fedriani, A. Caratti o Garatti, S. J. D. Purser +7
It is important to determine if massive stars form via disc accretion, like their low-mass counterparts. Theory and observation indicate that protostellar jets are a natural conseq…
A search for non-thermal radio emission from jets of massive young stellar objects
W. O. Obonyo, S. L. Lumsden, M. G. Hoare +3
Massive young stellar objects (MYSOs) have recently been shown to drive jets whose particles can interact with either the magnetic fields of the jet or ambient medium to emit non-t…
