SPYGLASS. VII-B. Tracing the Fragments of Massive Star Formation Using Low-Mass Associations
Ronan Kerr, Adam L. Kraus, Jonathan C. Tan +6
New observations from the Gaia spacecraft have traced an emerging demographic of low-mass associations disconnected from larger associations or GMCs. The first of these association…
Homogeneous Stellar Parameters from Heterogeneous Spectra with Deep Learning
Jeff Shen, Joshua S. Speagle, Shirley Ho
Large-scale spectroscopic surveys have collectively observed millions of stars across the Milky Way, but each derives stellar labels using independent pipelines with distinct model…
Disk Wind Feedback from High-mass Protostars. V. Application of Multi-Modal Machine Learning to Characterize Outflow Properties
Duo Xu, Ioana A. Stelea, Joshua S. Speagle +2
Characterizing protostellar outflows is fundamental to understanding star formation feedback, yet traditional methods are often hindered by projection effects and complex morpholog…
It's a matter of time: Empirical Constraints on Supernova Yields and Delay Times from Dwarf Spheroidal Galaxies
Mairéad E. Heiger, Alexander P. Ji, Joshua S. Speagle +6
The chemical abundances of a stellar population encode information about nucleosynthesis and its astrophysical sites, but this information is confounded by the specific star format…
Assessing Zeeman Measurements of Magnetic Fields in Synthetic HI Observations
Duo Xu, Peter Martin, Stella Offner +3
Zeeman observations provide the only direct probe of line-of-sight (LOS) magnetic fields in the interstellar medium. To evaluate their accuracy and limitations, we generate synthet…
SPYGLASS. VII-A. The Demographics and Ages of Small Nearby Young Associations
Ronan Kerr, Facundo PeÅez Paolino, Jonathan C. Tan +5
Recent Gaia-based young stellar association surveys have revealed dozens of low-mass populations that have, until recently, been too small or sparse to detect. These populations re…
