Proper Motions of Massive Stars in 30 Doradus
We propose an ambitious proper motion survey of massive stars in the 30 Doradus region of the Large Magellanic Cloud using the unique capabilities of HST. We will derive the directions of motion of massive runaway stars, searching in particular for massive stars which have been ejected from the central very massive cluster R136. These data will be combined with radial velocities from the VLT-FLAMES Survey of the Tarantula Nebula and with atmospheric analyses and stellar evolution models to constrain their origins. We will also search for very young isolated massive stars to test models of single-star formation. This work is highly relevant to star formation, cluster dynamics, the origin of field WR stars and GRBs, the creation of very massive stars by runaway mergers, and the possible formation of intermediate-mass black holes.
This is the first epoch of a two-epoch astrometric program.
Observations of epoch I need to be taken as soon as possible.
All visits will have the same orient of visit01.
The first epoch needs to be taken at an ORIENT angle that will allow a second epoch at ORIENT+180degree
if we want a color information. ...indeed, the GD is going to change anyway. We will perform selfcalibration
within each epoch.
