Kavli Affiliate: Roland Vanderspek | First 5 Authors: Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan, Chenyang Ji, Zitao Lin | Summary: The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 […]

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport, James Munday, Hai-Liang Chen | Summary: We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments the population of mass-transferring binaries at […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Zi-Hang Zhu, Ying Liu, Gianluca Lagnese, Federica Maria Surace, Wei-Yong Zhang | Summary: In the context of quantum electrodynamics, the decay of false vacuum leads to the production of electron-positron pair, a phenomenon known as the Schwinger effect. In practical experimental scenarios, producing a pair requires an […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Xuejian Shen, Mark Vogelsberger, Daniel Gilman, Stephanie O’Neil | Summary: We present a novel density profile for halos in self-interacting dark matter (SIDM) models, which accurately captures the flat- and isothermal-core configurations. We show analytically how our density profile satisfies these conditions, with comparisons to […]

Kavli Affiliate: Moritz Guenther | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón, Dustin K. Swarm, Joy S. Nichols | Summary: We investigated the temporal and spectral features of $gamma$ Cassiopeiae’s X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the X-ray […]
