J/PASJ/64/4 SiO maser survey of nearby red variables (Deguchi+, 2012) ================================================================================ Kinematics of red variables in the Solar neighborhood. I. Basic data obtained by an SiO maser survey Deguchi S., Sakamoto T., Hasegawa T. =2012PASJ...64....4D ================================================================================ ADC_Keywords: Stars, nearby ; Stars, variable ; Masers ; Radial velocities Keywords: Galaxy: disk - Galaxy: kinematics and dynamics - stars: AGB and post-AGB 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.
