NICER observations of thermonuclear bursts from 4U 1728-34: Detection of oscillations prior to the onset of two bursts

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Funda Bostanci, Tugba Boztepe, Tolga Guver, Tod E. Strohmayer, Yuri Cavecchi | Summary: We present temporal and time-resolved spectral analyses of all the thermonuclear X-ray bursts observed from the neutron star low-mass X-ray binary (LMXB) 4U 1728-34 with NICER from June 2017 to September 2019. In total, […]

Emergent Chern-Simons Interactions in 3+1 Dimensions

Kavli Affiliate: Frank Wilczek | First 5 Authors: Marcus Stålhammar, Darya Rudneva, Thors Hans Hansson, Frank Wilczek, | Summary: Parity violating superconductors can support a low-dimension local interaction that becomes, upon condensation, a purely spatial Chern-Simons term. Solutions to the resulting generalized London equations can be obtained from solutions of the ordinary London equations with […]

TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b

Kavli Affiliate: Sara Seager | First 5 Authors: Stephanie Yoshida, Shreyas Vissapragada, David W. Latham, Allyson Bieryla, Daniel P. Thorngren | Summary: We present the discovery of TOI-1420b, an exceptionally low-density ($rho = 0.08pm0.02$ g cm$^{-3}$) transiting planet in a $P = 6.96$ day orbit around a late G dwarf star. Using transit observations from […]

Quasi-periodic oscillations during magnetar giant flares in the strangeon star model

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yacheng Kang, Zexin Hu, Lijing Shao, Cheng-Jun Xia | Summary: Soft gamma-ray repeaters (SGRs) are widely understood as slowly rotating isolated neutron stars. Their generally large spin-down rates, high magnetic fields, and strong outburst energies render them different from ordinary pulsars. In a few giant […]

Stability of Taylor-Couette Flow with Odd Viscosity

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Guangle Du, Rudolf Podgornik, , , | Summary: Odd viscosity can emerge in 3D hydrodynamics when the time reversal symmetry is broken and anisotropy is introduced. Its ramifications on the stability of the prototypical Taylor-Couette flow in curved geometries have remained unexplored. Here, we investigate the effects […]
