Abstract:
We report on the first 1432 sources observed using the Atacama Large
Millimeter/submillimeter Array, from the Bulge Asymmetries and
Dynamical Evolution survey, which aims to obtain tens of thousands of
line-of-sight velocities from SiO masers in Asymptotic Giant Branch
(AGB) stars in the Milky Way. A 71% detection rate of 86GHz SiO masers
is obtained from the infrared color-selected sample and increases to
80% when considering the likely oxygen-rich stars using Midcourse
Space Experiment colors isolated in a region where [D]-[E]≤1.38.
Based on Galactic distributions, the presence of extended CS emission,
and likely kinematic associations, the population of sources with
[D]-[E]>1.38 probably consists of young stellar objects, or
alternatively, of planetary nebulae. For the SiO detections, we
examined whether individual SiO transitions provide comparable stellar
line-of-sight velocities and found that any SiO transition is suitable
for determining a stellar AGB line-of-sight velocity. Finally, we
discuss the relative SiO detection rates and line strengths in the
context of current pumping models.
Description:
Observations were made during the Atacama Large Millimeter/submillimeter
Array (ALMA) Cycles 2, 3, and 5 (2014 June through 2018 September).
