The Subaru Seminar is
usually held in Room 104 of the Hilo Base Facility, adjacent
to the main lobby. Everyone is welcome to attend. If you are

" Pulsating stars as tracers of the structure and evolution of the Milky Way "
(Univ. of Tokyo)
Pulsating stars are useful tracers of the Milky Way and nearby galaxies.
However, survey of these stars in the Milky Way is far from complete
mainly due to the large extinction towards the Galactic bulge and disk.
We are conducting a photometric survey of pulsating stars
using 1-m class telescopes, and we have discovered the objects
in the obscured regions such as classical Cepheids near the Galactic center.
In order to investigate the kinematics and chemical evolution of
the Galaxy, we are carrying out spectroscopic observations of
these new targets using IRCS and FMOS at SUBARU.
In 2012, we used the IRCS to collect H-band spectra of
the Galactic center Cepheids. I will discuss their kinematics
and the connection to the nuclear stellar disk with
a radius ~200 pc around the Galactic center.
Seminars are also held at JAC,
