Abstract of the proposal for the experiment RD001 |
|
We propose first epoch observation of a high-mass young stellar object, which has recently bursted at 6.7 GHz methanol maser line. The aim is to measure the maser position with a few mas accuracy and to explore the spot distribution and velocity structure of the maser emission in an accretion burster candidate at very early stage of flare. The EVN data together with high cadence single dish monitoring at many transitions will allow us to test plausible causes of maser variations including sudden changes in the accretion rate. |
