Abstract:
In order to study the streaming motions of miras in the Solar
neighborhood, we newly surveyed 379 red variables in the SiO maser
lines at 42.821 and 43.122GHz with the Nobeyama 45m radio telescope.
Accurate radial velocities were obtained for 229 (220 new) detected
stars. The sample was selected from optical variables found by new
automated surveys: the Northern Sky Variability Survey and the All Sky
Automated Survey. The new sample consists of "bluer" objects
compared with those observed in the previous SiO surveys. The
distances to the objects were estimated using the period-luminosity
relation, and they are mostly less than 3kpc from the Sun. The
longitude-velocity diagram reveals three prominent groups of stars
deviant from circular galactic rotation with a flat rotation curve. In
addition to the Hercules group of stars, which was studied before, we
found two new deviant groups: one toward the Perseus arm and the other
toward the Sagittarius arm. These two groups both exhibit anomalous
motions toward the galactic center, which seem to be consistent with
the noncircular motions of these spiral arms found in recent VLBI
proper-motion measurements for maser gas clumps.
Description:
The observations were made with the 45m radio telescope at Nobeyama
in 2009 March, 2010 March-May, and 2010 December-2011 January in
the SiO J=1-0 v=1 and 2 transitions at 43.122 and 42.821GHz,
respectively. A few data taken before 2009 were also added for the
present analysis.
