| Abstract: |
We present the spatial distribution of the Mira
variable stars (Miras) in the
Galactic halo up to 100 kpc.We make a sample of 196 red stars in the
Galactic latitudes b > 30°,
and perform repeated observations over 3 years by 105-cm telescope at
Kiso Observatory.
We discover 16 Mira variable stars.
We find that many of these Miras are located near the Sagittarius
(Sgr) stream,
as opposed to the spatially unbiased sample.
We also detect one or two Miras toward the metal-poor Sextans dSph. |
