Dual Gauge Theory for Two Dimensional Superfluid Turbulence
Tobias Helbig, Sayak Bhattacharjee, Srinivas Raghu
We describe turbulent hydrodynamics of superfluids in two spatial dimensions via the dynamics of point-like vortices coupled to an emergent 2+1 dimensional gauge field. The…
PANTERA. I. Hunting for the Most Metal-Rich Stars in the Solar Neighborhood with High-Resolution Spectroscopy
Serat M. Saad, D. M. Rowan, K. Z. Stanek +4
The paper presents the PANTERA high‑resolution spectroscopic survey of 56 nearby metal‑rich stars, measuring their iron abundances and finding many ultra‑metal‑rich objects while e…
A Systematic Search for Big Dippers in ASAS-SN
B. JoHantgen, D. M. Rowan, R. Forés-Toribio +6
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplan…
ASASSN-24fw: An 8-month long, 4.1 mag, optically achromatic and polarized dimming event
R. Forés-Toribio, B. JoHantgen, C. S. Kochanek +20
We discuss ASASSN-24fw, a 13th-magnitude star that optically faded by mag starting in September 2024 after over a decade of quiescence in ASAS-SN. The dimmimg…
Astronomical Cardiology: A Search For Heartbeat Stars Using and
Jowen Callahan, D. M. Rowan, C. S. Kochanek +1
Heartbeat stars are a subclass of binary stars with short periods, high eccentricities, and phase-folded light curves that resemble an electrocardiogram. We start from the $\textit…
Precise and Accurate Mass and Radius Measurements of Fifteen Galactic Red Giants in Detached Eclipsing Binaries
D. M. Rowan, K. Z. Stanek, C. S. Kochanek +9
Precise and accurate mass and radius measurements of evolved stars are crucial to calibrating stellar models. Stars in detached eclipsing binaries (EBs) are excellent potential cal…
