Confidently Wrong: Why Ignoring Binaries Biases IMF Inference at Large Sample Sizes
Anna L. Rosen
The stellar initial mass function (IMF) high-mass slope is routinely measured by fitting single-star models to photometric samples that contain unresolved binaries. This practi…
Taming the Tarantula: How Stellar Wind Feedback Shapes Gas and Dust in 30 Doradus

Constraining the Diffusion Coefficient and Cosmic-Ray Acceleration Efficiency using Gamma-ray Emission from the Star-Forming Region RCW 38
Paarmita Pandey, Laura A. Lopez, Anna L. Rosen +3
Stellar winds from massive stars may be significant sources of cosmic rays (CRs). To investigate this connection, we report a detailed study of gamma-ray emission near the young Mi…

Trinity L. Webb, Jennifer A. Rodriguez, Laura A. Lopez +6
We present the first Chandra X-ray observations of H72.97-69.39, a highly-embedded, potential super-star cluster (SSC) in its infancy located in the star-forming complex N79 of the…
Stellar Populations in STARFORGE: The Origin and Evolution of Star Clusters and Associations
Juan P. Farias, Stella S. R. Offner, Michael Y. Grudić +2
Most stars form in highly clustered environments within molecular clouds, but eventually disperse into the distributed stellar field population. Exactly how the stellar distributio…
What Sets the Star Formation Rate of Molecular Clouds? The Density Distribution as a Fingerprint of Compression and Expansion Rates
Sabrina M. Appel, Blakesley Burkhart, Vadim A. Semenov +3
We use a suite of 3D simulations of star-forming molecular clouds, with and without stellar feedback, magnetic fields, and driven turbulence, to study the compression and expansion…
A Multiwavelength Study of the Massive Colliding Wind Binary WR 20a: A Possible Progenitor for Fast-Spinning LIGO Binary Black Hole Mergers
Grace M. Olivier, Laura A. Lopez, Katie Auchettl +7
WR 20a is the most massive close-in binary known in our Galaxy. It is composed of two 80 M Wolf-Rayet stars with a short period of 3.7 days in the open cl…
Effects of the environment on the multiplicity properties of stars in the STARFORGE simulations
Dávid Guszejnov, Aman N. Raju, Stella S. R. Offner +4
Most observed stars are part of a multiple star system, but the formation of such systems and the role of environment and various physical processes is still poorly understood. We…
The TEMPO Survey I: Predicting Yields of the Transiting Exosatellites, Moons, and Planets from a 30-day Survey of Orion with the Nancy Grace Roman Space Telescope
Mary Anne Limbach, Melinda Soares-Furtado, Andrew Vanderburg +12
We present design considerations for the Transiting Exosatellites, Moons, and Planets in Orion (TEMPO) Survey with the Nancy Grace Roman Space Telescope. This proposed 30-day surve…
Effects of the environment and feedback physics on the initial mass function of stars in the STARFORGE simulations
Dávid Guszejnov, Michael Y. Grudić, Stella S. R. Offner +3
One of the key mysteries of star formation is the origin of the stellar initial mass function (IMF). The IMF is observed to be nearly universal in the Milky Way and its satellites,…
A Massive Star is Born: How Feedback from Stellar Winds, Radiation Pressure, and Collimated Outflows Limits Accretion onto Massive Stars
