Confirming Transiting Neptunes and M Dwarf Planets From HAT

(Abstract)
We propose for two nights on Subaru/HDS to obtain high-precision RV 
observations of four very promising candidate transiting planet systems 
from the HAT ground-based transit surveys. Two of the candidates are potential 
Neptune-mass planets, and two are very short period candidates around M dwarf 
stars. The proposed observations will allow us to confirm these planets, 
measure their masses, and characterize the host stars. If confirmed, these 
planets would represent a valuable addition to the small sample of well-
characterized low-mass planets and planets around M dwarfs. Moreover, several 
of the objects would be planetary systems with unique properties, making them 
of great interest for future follow-up studies.
