Extending asteroseismic magnetometry across the diverse landscape of magnetic structures
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
Magnetic fields have now been asteroseismically measured in the cores of many red giants. However, most interpretations of these measurements assume that the magnetic field is far…
Asteroseismic imprints of strong non-axisymmetric fields in the cores of red giants
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
To date, magnetic fields have been asteroseismically measured in nearly one hundred red giant cores. However, most analyses assume weak magnetic fields and slow rotation so that pe…
Connecting Cores and Black Hole Dynamics Across Scales: From Globular Clusters to Massive Ellipticals
Kyle Kremer, Newlin C. Weatherford, Philip F. Hopkins +2
The centers of massive elliptical galaxies exhibit a wide range in density profiles, from central cusps to resolved cores with order kiloparsec sizes. The cored ellipticals have be…
Structure and Dynamics of the Young Massive Star Cluster Westerlund 1
Lingfeng Wei, Matthew W. Hosek, Jessica R. Lu +8
We present a structural analysis of the young massive star cluster Westerlund 1 (Wd 1). With multi-epoch Hubble Space Telescope (HST) observations, we measure the proper motions of…
Atmospheric heating and magnetism driven by Ne distillation in isolated white dwarfs
A. F. Lanza, N. Z. Rui, J. Farihi +2
The origin of atmospheric heating in the cool, magnetic white dwarf GD 356 remains unsolved nearly 40 years after its discovery. This once idiosyncratic star with $T_{\rm eff}\appr…
Finding the unusual red giant remnants of cataclysmic variable mergers
Nicholas Z. Rui, Jim Fuller
Mergers between helium white dwarfs and main-sequence stars are likely common, producing red giant-like remnants making up roughly a few percent of all low-mass (…
Asteroseismic g-mode period spacings in strongly magnetic rotating stars
Nicholas Z. Rui, J. M. Joel Ong, Stéphane Mathis
Strong magnetic fields are expected to significantly modify the pulsation frequencies of waves propagating in the cores of red giants or in the radiative envelopes of intermediate-…
A close-in giant planet escapes engulfment by its star
Marc Hon, Daniel Huber, Nicholas Z. Rui +39
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, c…
Gravity waves in strong magnetic fields
Nicholas Z. Rui, Jim Fuller
Strong magnetic fields in the cores of stars are expected to significantly modify the behavior of gravity waves: this is likely the origin of suppressed dipole modes observed in ma…
Compact Object Modeling in the Globular Cluster 47 Tucanae
Claire S. Ye, Kyle Kremer, Carl L. Rodriguez +5
The globular cluster 47~Tucanae (47~Tuc) is one of the most massive star clusters in the Milky Way and is exceptionally rich in exotic stellar populations. For several decades it h…
Asteroseismic Fingerprints of Stellar Mergers
Nicholas Z. Rui, Jim Fuller
Stellar mergers are important processes in stellar evolution, dynamics, and transient science. However, it is difficult to identify merger remnant stars because they cannot easily…
Modeling Dense Star Clusters in the Milky Way and Beyond with the Cluster Monte Carlo Code
Carl L. Rodriguez, Newlin C. Weatherford, Scott C. Coughlin +10
We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star -body code for modeling dense star clusters. CMC treats collisional stellar dynamic…
White Dwarf Subsystems in Core-Collapsed Globular Clusters
Kyle Kremer, Nicholas Z. Rui, Newlin C. Weatherford +5
Numerical and observational evidence suggests that massive white dwarfs dominate the innermost regions of core-collapsed globular clusters by both number and total mass. Using NGC…
No Black Holes in NGC 6397
Nicholas Z. Rui, Newlin Weatherford, Kyle Kremer +5
Recently, \citet{vitral2021does} detected a central concentration of dark objects in the core-collapsed globular cluster NGC 6397, which could be interpreted as a subcluster of ste…
Matching Globular Cluster Models to Observations
Nicholas Z. Rui, Kyle Kremer, Newlin C. Weatherford +4
As ancient, gravitationally bound stellar populations, globular clusters are abundant, vibrant laboratories characterized by high frequencies of dynamical interactions coupled to c…
Modeling Dense Star Clusters in the Milky Way and Beyond with the Cluster Catalog
Kyle Kremer, Claire S. Ye, Nicholas Z. Rui +6
We present a set of 148 independent -body simulations of globular clusters (GCs) computed using the code (). At an age of $\sim10-13…
The Quintuplet Cluster: Extended Structure and Tidal Radius
Nicholas Z. Rui, Matthew W. Hosek, Jessica R. Lu +4
The Quintuplet star cluster is one of only three known young ( Myr) massive (M M) clusters within pc of the Galactic Center. In order to explore star…
Star Formation in Different Environments: The Initial Mass Function
M. W. Hosek, J. R. Lu, M. Andersen +7
The stellar initial mass function (IMF) is a fundamental property of star formation, offering key insight into the physics driving the process as well as informing our understandin…
Imaging stress and magnetism at high pressures using a nanoscale quantum sensor
S. Hsieh, P. Bhattacharyya, C. Zu +15
Pressure alters the physical, chemical and electronic properties of matter. The development of the diamond anvil cell (DAC) enables tabletop experiments to investigate a diverse la…
Imaging the local charge environment of nitrogen-vacancy centers in diamond
Thomas Mittiga, Satcher Hsieh, Chong Zu +8
Characterizing the local internal environment surrounding solid-state spin defects is crucial to harnessing them as nanoscale sensors of external fields. This is especially germane…
