Characterizing the Evolved Stellar Population in the Galactic Foreground I: Bolometric Magnitudes, Spatial Distribution and P-L Relations
Luis Henry Quiroga-Nuñez, Huib Jan van Langevelde, Loránt O. Sjouwerman +6
Radio campaigns using maser stellar beacons have provided crucial information to characterize Galactic stellar populations. Currently, the Bulge Asymmetries and Dynamical Evolution…
Infrared color separation between thin-shelled oxygen-rich and carbon-rich AGB stars
Megan O. Lewis, Ylva M. Pihlström, Loránt O. Sjouwerman +1
We present 43 GHz VLA spectra for 51 AGB sources with the goal of verifying an infrared (IR) color cut intended to separate Carbon-rich (C) and Oxygen-rich (O) AGB sources througho…
The Synergy between VLBI and Gaia astrometry
Huib van Langevelde, Luis Henry Quiroga-Nuñez, Wouter Vlemmings +10
With the publication of Gaia DR2, 1.3 billion stars now have public parallax and proper motion measurements. In this contribution, we compare the results for sources that have both…
Maser, infrared and optical emission for late-type stars in the Galactic plane
L. H. Quiroga-Nuñez, H. J. van Langevelde, L. O. Sjouwerman +4
Radio astrometric campaigns using VLBI have provided distances and proper motions for masers associated with young massive stars (BeSSeL survey). The ongoing BAaDE project plans to…
Finding evolved stars in the inner Galactic disk with Gaia
L. H. Quiroga-Nuñez, H. J. van Langevelde, Y. M. Pihlström +2
The Bulge Asymmetries and Dynamical Evolution (BAaDE) survey will provide positions and line-of-sight velocities of ~20,000 evolved, maser bearing stars in the Galactic plane. Alth…
Class I Methanol (CHOH) Maser Conditions near Supernova Remnants
Bridget C. McEwen, Ylva M. Pihlström, Loránt O. Sjouwerman
We present results from calculations of the physical conditions necessary for the occurrence of 36.169 (), 44.070 (), 84.521 ()…
