Comparison AOLSG vs. HST

• Pro AO
• Higher spatial resolution in JH
• Access to the K band
• Access to thermal IR
• larger field-of-view (for GLAO)
• more suitable for large surveys

• Pro HST
• Deeper in JH
• Access to optical
• stable and simpler PSF
• larger field-of-view (for DL)
• no need for T/T star

Stellar disks and Jets
Disks and Jets extraction of excess angular
moment, efficiency of formation exact nature of
acceleration of the jet is unclear jet rotation
and precession? peculiar velocity fields, bow
shocks
