Membership lists for 431 open clusters in Gaia DR2 using extreme deconvolution gaussian mixture models

Karl Jaehnig, Jonathan Bird, Kelly Holley-Bockelmann

Open clusters are groups of stars that form at the same time, making them an ideal laboratory to test theories of star formation, stellar evolution, and dynamics in the Milky Way d…

Close companions around young stars

Marina Kounkel, Kevin Covey, Maxwell Moe +26

Multiplicity is a fundamental property that is set early during stellar lifetimes, and it is a stringent probe of the physics of star formation. The distribution of close companion…

Radius Inflation at Low Rossby Number in the Hyades Cluster

Karl Jaehnig, Garrett Somers, Keivan Stassun

Radius inflation continues to be explored as a peculiar occurrence among magnetically active, low-mass stars. Recently Somers et. al. 2017 showed that radius inflation among low-ma…

The APOGEE-2 Survey of the Orion Star Forming Complex II: Six-dimensional structure

Marina Kounkel, Kevin Covey, Genaro Suárez +17

We present an analysis of spectrosopic and astrometric data from APOGEE-2 and Gaia DR2 to identify structures towards the Orion Complex. By applying a hierarchical clustering algor…

IN-SYNC. VII. Evidence for a decreasing spectroscopic binary fraction from 1 to 100 Myr within the IN-SYNC sample

Karl Jaehnig, Jonathan C. Bird, Keivan G. Stassun +4

We study the occurrence of spectroscopic binaries in young star-forming regions using the INfrared Spectroscopy of Young Nebulous Clusters(IN-SYNC) survey, carried out in SDSS-III…

The Structural Evolution of Forming and Early Stage Star Clusters

Karl O. Jaehnig, Nicola Da Rio, Jonathan C. Tan

We study the degree of angular substructure in the stellar position distribution of young members of Galactic star-forming regions, looking for correlations with distance from clus…

The Structure, Dynamics and Star Formation Rate of the Orion Nebula Cluster

Nicola Da Rio, Jonathan C. Tan, Karl Jaehnig

The spatial morphology and dynamical status of a young, still-forming stellar cluster provide valuable clues on the conditions during the star formation event and the processes tha…
