A Modified Conveyor Belt Model: Implications for Surface Density Thresholds for Massive Star Formation
Nicholas Larose, C. R. Kerton, Kathryn Devine +1
Recent models and simulations of cluster formation within molecular clumps consider multi-scale, hierarchical accretion, which leads to clump mass growth over time. This mode of ma…
The Milky Way Bulge Extra-Tidal Star Survey: NGC 6569
Joanne Hughes, Andrea Kunder, Kevin Covey +25
We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution (R ~ 11,000) Anglo-Australian Telescope spectra o…
The Milky Way Project: Bridging Intermediate- and High-Mass Star Formation with the MIRION Catalog of Yellowballs
Kathryn Devine, Grace Wolf-Chase, C. R. Kerton +7
We describe the construction and use of the Mid-InfraRed Interstellar Objects and Nebulae (MIRION) catalog, which was compiled from 6176 objects identified as "yellowballs" (YBs) b…
The Galactic Bulge exploration VI.: Gaia Enceladus/Sausage RR Lyrae stars in the inner-central stellar halo of the Milky Way
Andrea Kunder, Zdenek Prudil, Antonela Monachesi +6
We present a view of the stellar halo in the inner-central regions of the Milky Way (R <~ 10 kpc) mapped by RR Lyrae stars. The combined BRAVA-RR/APOGEE RR Lyrae catalog is used to…
The Galactic Bulge exploration III.: Calcium Triplet Metallicities for RR Lyrae Stars
Andrea Kunder, Zdenek Prudil, Claire Skaggs +5
RR Lyrae stars are excellent tracers of stellar populations for old, metal-poor components in the Milky Way Galaxy and the Local Group. Their luminosities have a metallicity-depend…
