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…
The High-resolution Accretion Disks of Embedded protoStars (HADES) simulations. I. Impact of Protostellar Magnetic Fields on the Accretion Modes
Brandt A. L. Gaches, Jonathan C. Tan, Anna L. Rosen +1
How embedded, actively accreting low-mass protostars accrete their mass is still greatly debated. Observations are now piecing together the puzzle of embedded protostellar accretio…
A Massive Star is Born: How Feedback from Stellar Winds, Radiation Pressure, and Collimated Outflows Limits Accretion onto Massive Stars
Anna L. Rosen
Massive protostars attain high luminosities as they are actively accreting and the radiation pressure exerted on the gas in the star's atmosphere may launch isotropic high-velocity…
Blowing Bubbles around Intermediate-Mass Stars: Feedback from Main-Sequence Winds is not Enough
Anna L. Rosen, Stella S. R. Offner, Michael M. Foley +1
Numerous spherical ``shells" have been observed in young star-forming environments that host low- and intermediate-mass stars. These observations suggest that these shells may be p…
The Role of Outflows, Radiation Pressure, and Magnetic Fields in Massive Star Formation
Anna L. Rosen, Mark R. Krumholz
Stellar feedback in the form of radiation pressure and magnetically-driven collimated outflows may limit the maximum mass that a star can achieve and affect the star-formation effi…
Zooming in on Individual Star Formation: Low- and High-mass Stars
Anna L. Rosen, Stella S. R. Offner, Sarah I. Sadavoy +3
Star formation is a multi-scale, multi-physics problem ranging from the size scale of molecular clouds (10s pc) down to the size scales of dense prestellar cores (0.1 p…
Formation and Evolution of Disks around Young Stellar Objects
Bo Zhao, Kengo Tomida, Patrick Hennebelle +9
Recent observations have suggested that circumstellar disks may commonly form around young stellar objects. Although the formation of circumstellar disks can be a natural result of…
Circumbinary Disks: Accretion and Torque as a Function of Mass Ratio and Disk Viscosity
Paul C. Duffell, Daniel D'Orazio, Andrea Derdzinski +4
Using numerical hydrodynamics calculations and a novel method for densely sampling parameter space, we measure the accretion and torque on a binary system from a circumbinary disk.…
Massive Star Formation via the Collapse of Subvirial and Virialized Turbulent Massive Cores
Anna L. Rosen, Pak Shing Li, Qizhou Zhang +1
Similar to their low-mass counterparts, massive stars likely form via the collapse of pre-stellar molecular cores. Recent observations suggest that most massive cores are subvirial…
An Unstable Truth: How Massive Stars get their Mass
Anna L. Rosen, Mark R. Krumholz, Christopher F. McKee +1
The pressure exerted by massive stars' radiation fields is an important mechanism regulating their formation. Detailed simulation of massive star formation therefore requires an ac…
Very Massive Stars in the Local Universe
Jorick S. Vink
Recent studies suggest the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical stel…
Gone With the Wind: Where is the Missing Stellar Wind Energy from Massive Star Clusters?
Anna L. Rosen, Laura A. Lopez, Mark R. Krumholz +1
Star clusters larger than contain multiple hot stars that launch fast stellar winds. The integrated kinetic energy carried by these winds is comparable to t…
Very Massive Stars (VMS) in the Local Universe
Jorick S. Vink, Alexander Heger, Mark R. Krumholz +25
Recent studies have claimed the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical…
What Sets the Initial Rotation Rates of Massive Stars?
Anna L. Rosen, Mark R. Krumholz, Enrico Ramirez-Ruiz
The physical mechanisms that set the initial rotation rates in massive stars are a crucial unknown in current star formation theory. Observations of young, massive stars provide ev…
